High or low water can alter a river cruise, but major disruptions are uncommon. Here is how often problems occur, where the vulnerable stretches are, what cruise lines do—and whether water levels should stop you from booking.
What today's readings can — and cannot — tell you about an upcoming river cruise.
What the drought revealed about rivers, ships, fleet size and choosing a cruise.
Compare ship swaps, coaches, hotels, refunds, credits and travel-insurance limits.
Rhine, Danube, Elbe, Seine, Rhône, Douro and canals do not respond to low water in the same way.
The bottom line: I would not let water-level concerns stop me from taking a European river cruise.
Conditions can change an itinerary, and occasionally they change a trip substantially. Yet in more than 50 European river cruises, I have never experienced a major disruption caused by either high or low water. Perhaps I have been fortunate, but the available data also indicate that serious problems are the exception—not the normal river-cruise experience. — Ralph Grizzle
Europe’s 2026 drought produced exceptionally low water on parts of the Rhine and Danube and caused ship swaps, changed embarkation points, motorcoach substitutions and some cancellations. Conditions vary greatly by river and can change quickly after rainfall.
What this does not tell us: Today’s river level is not a forecast for a cruise several weeks or months from now. Rainfall, winter snowpack, the timing of snowmelt and short-term weather will determine future conditions. For an upcoming sailing, the most useful information is the condition of the specific river stretch, whether your particular ship can navigate it and what your cruise line plans to do if it cannot.
The numbers below are gauge readings, not the depth of the river and not the amount of water beneath a river ship. Each gauge has its own reference point, so a reading of 223 cm on the Danube cannot be compared directly with 18 cm on the Rhine.
What matters is whether a particular reading creates navigation restrictions for a particular ship. There is no single “normal” or “safe” water level that applies to every river cruise ship.
Important: These classifications describe the gauge reading, not the depth of the river or whether a particular river-cruise ship can pass. Navigability depends on the ship’s draft, available channel depth and current local conditions.
No industry-wide database records every missed port, changed dock, ship swap or cancellation. Cruise lines also use different definitions of “affected,” making precise comparisons impossible.
Source: AmaWaterways COO Jon Burrows, as reported by AFAR. This is one cruise line’s estimate—not a verified industry-wide rate—and includes both high and low water as well as different degrees of itinerary change.
If that 3.5% rate were broadly representative of Europe’s 1.39 million annual river-cruise passengers, it would equate to approximately 49,000 passengers experiencing some type of water-related change in an average year. That is an illustration, not a measured passenger count. No reliable public data separate high-water disruptions from low-water disruptions.
The phrase affected by water levels is also broader than it sounds. It might mean docking in a nearby town instead of the scheduled port. At the other extreme, it could mean completing part of the itinerary by coach or having the cruise cancelled. Those are very different experiences.
My experience: I once felt our ship touching the bottom of the Rhine near Rüdesheim during unusually low water in November 2015, but we continued. I have also completed a ship swap for reasons unrelated to a major water-level disruption. The process was well organized, but it illustrates why the size of a cruise line’s fleet—and the availability of nearly identical sister ships—can matter.
River ships operate within narrow margins. Below the ship is its draft: the distance between the waterline and the bottom of the hull. In shallow conditions there may be very little water beneath the keel. River ships are therefore designed with remarkably shallow drafts.
Above the ship is its air draft: the height between the waterline and the vessel’s highest point. When the river rises, a ship may be unable to fit beneath a bridge. That is why many river ships have collapsible railings, removable sun-deck furniture and navigation bridges that can lower into the deck.
Low water can prevent a ship from crossing a shallow section. High water can close locks, create unsafe currents or make bridge clearance impossible. More water is not necessarily better.
A report that “the Danube is low” does not mean the entire 1,770-mile river is unnavigable. Problems are normally concentrated at particular shallow passages, bridges, locks or ports.
| River or route | Pressure points | What travelers should know |
|---|---|---|
| Upper Danube | Shallow stretches between Regensburg and Passau/Vilshofen; bridges and locks during high water | Amsterdam–Budapest and Nuremberg–Budapest itineraries cross several potential bottlenecks. |
| Middle and Lower Danube | Extended summer heat and drought; shallow approaches to certain ports | A ship may dock outside the scheduled city or require a coach transfer even when other sections remain open. |
| Rhine | The shallow passage around Kaub and the Rhine Gorge | Low water can affect through-cruises between Amsterdam and Basel; large fleets may use ship swaps. |
| Main–Danube Canal | Low bridges and lock restrictions | High water can be as disruptive as low water because ships may not clear bridges. |
| Elbe | Naturally shallow and highly variable conditions | The Elbe is among Europe’s most water-level-sensitive cruise rivers. |
| Po | Drought and low flow | Few companies operate conventional cruises because navigation can be unreliable. |
| Seine | High water and bridge clearance near Paris | Sailings may operate while using an alternative docking point outside central Paris. |
| Rhône and Saône | Heavy rain, high water and strong currents | Closures tend to be localized and dependent on short-term weather. |
| Douro | Locks, dams and occasional operational restrictions | Regulation by dams generally makes levels more manageable, though no river is disruption-proof. |
There is no risk-free month. These are broad seasonal tendencies—not forecasts or guarantees.
These seasonal patterns describe common tendencies only. High and low water can occur outside these periods.
Current river levels have little predictive value for a cruise several months away. A dry August does not tell us what the Danube will look like the following April. Winter precipitation and snowpack, followed by the timing of spring rainfall and snowmelt, can completely reset conditions.
Because conditions can change after a single period of rain, cruise lines usually try to preserve the trip rather than cancel it prematurely. Their options include:
Companies with large European fleets and nearly identical sister ships may have more options for ship swaps. A shallow-draft vessel may be able to continue after a deeper-draft ship has stopped. Smaller companies can deliver outstanding cruises, but may have fewer replacement vessels available when a route becomes impassable.
The response varies considerably by company. Some lines rely heavily on sister-ship swaps, while others publish specific limits on motorcoach substitutions or compensation. We compare AmaWaterways, Avalon Waterways, CroisiEurope, Emerald Cruises, Riviera Travel, Riverside Luxury Cruises, Scenic, Uniworld and Viking in our cruise-line low-water protection guide .
Before booking, ask:
A 2026 example: how AmaWaterways responded. During the historically low water of summer 2026, AmaWaterways reported making operational adjustments on portions of the Danube, Rhine and Main without cancelling a departure because of the conditions. Its responses included rerouting ships, reversing itineraries, adding time in certain cities, substituting motorcoach transportation and performing sister-ship swaps.
During a ship swap, guests typically leave for a scheduled excursion while their luggage is transferred to a corresponding cabin aboard a sister ship on the other side of the unnavigable stretch. This can preserve much of the cruise experience, although it should still be regarded as an itinerary change rather than an entirely unaffected sailing.
Source: AmaWaterways, July 2026 . These are the cruise line’s own reported results and operational descriptions.
We compared the published low-water policies and operating practices of AmaWaterways, Avalon Waterways, CroisiEurope, Emerald Cruises, Riviera Travel, Riverside Luxury Cruises, Scenic, Uniworld and Viking.
Our comparison chart looks at sister-ship swaps, motorcoach substitutions, hotels, refunds and credits, notification policies and what happens when an embarkation point changes. Riviera Travel, for example, publishes unusually specific limits on coach travel and ship-swap transfers.
See The Cruise-Line Comparison Chart →If you cancel voluntarily, ordinary cancellation penalties may apply. Wait for the cruise line to explain whether the sailing will operate and what alternatives, credits or refunds it is offering. Review your booking contract and travel-insurance policy carefully; standard insurance does not necessarily cover a voluntary cancellation prompted by concern about river levels.
If your cruise is still months away, monitoring today’s gauge readings is unlikely to help. If departure is within a week or two, ask your cruise line or advisor about the specific ship and itinerary—not simply whether the river as a whole is “high” or “low.”
A reader recently asked whether, given the low water in August 2026, I would proceed with a Danube cruise in April 2027. Our answer is yes.
The broader principle will remain true after those dates have passed: current conditions cannot predict the Danube many months from now. Low water is generally less likely to be the principal concern in April than after a long, hot summer. High water is possible during spring, but a major disruption remains uncommon and cannot be forecast that far ahead.
No river cruise is entirely without risk. I would choose a company with a strong operational record, understand its policies, consider suitable travel insurance—and go.
Gauge readings are useful only when interpreted in relation to a particular ship, route and critical passage. A number that is navigable for one vessel may be too low—or too high—for another.
Europe’s rivers have always risen and fallen. River cruises have dealt with significant low-water years including 2003, 2015, 2018, 2022 and 2026, while high water has caused major disruptions in other years.
What has changed is the industry’s ability to adapt. Larger fleets, more nearly identical sister ships, shallower-draft vessels and better logistics can allow many cruises to continue even when a particular stretch becomes unnavigable.
That history is worth keeping in perspective: water-level disruption is a real risk, but it is not a new one — and it remains the exception rather than the normal river-cruise experience.
No. Seasonal patterns can describe general tendencies, but useful operational forecasts are short term. Conditions months ahead depend on weather that has not yet occurred.
No dependable industry-wide figures divide disruptions between the two. Low water receives more attention during severe summer droughts, but high water can also stop ships from passing beneath bridges or through locks.
Not necessarily. On lines with nearly identical sister ships, guests may return to the same cabin layout after transferring around the blocked stretch. It is inconvenient, but considerably less disruptive than converting the remainder of the cruise into a hotel-and-coach tour.
Coverage varies. A policy may cover certain delays, interruptions or supplier cancellations, but concern about possible low water is generally not by itself a covered reason to cancel. Read the policy rather than relying on a general assurance that the trip is “insured.”
No European river is completely immune. The Elbe and Po are especially sensitive, while regulated waterways may be more manageable. The itinerary, ship design, fleet size and cruise line’s contingency planning are often as important as the river itself.
Compare itineraries, cruise lines, inclusions and real-world pricing on Europe’s most popular rivers.

Please keep the comments in perspective: Travelers whose cruises are disrupted are understandably more likely to post than those whose trips operate normally. The reports below are valuable eyewitness accounts, but they are not a representative sample of all European river cruises.
If you are currently cruising—or have recently returned—please share the river, route, cruise line, sailing date and what actually changed. That information is far more useful to other travelers than a river-level number by itself.
About the figures: The 2024 European passenger total comes from the Central Commission for the Navigation of the Rhine’s 2025 Annual Market Observation. The 3.5% figure is AmaWaterways’ estimate of the average share of its European departures affected by high or low water, reported by AFAR in 2026. Applying that percentage to all European passengers produces an illustrative estimate, not an audited industry total.

I’m currently on the Viking Vili halfway into our trip travelling Budapest to Amsterdam. We have been very fortunate as we will make it the whole way on the same boat. Though the water levels are very high so we are not allowed on the top deck (all the railings have been removed) because the bridges are low. There isn’t a way to predict what it will be like on your trips as the weather makes the determination and conditions can change quickly. We have been lucky, sunny weather every day but hot.
Yes, what can you tell me? Thanks………Nick who is scheduled to depart Basel on Sept. 1st
We’re boarding the Viking Atla on 9/3 for the cruise to Budapest. I don’t think that low water will be a problem. I’ve been keeping an eye on the water levels using this site… https://www.pegelonline.wsv.de/gast/karte/standard
You can check the Regensburg, Bavaria, Germany 10-Day Weather Forecast here… https://www.wunderground.com/forecast/de/regensburg
Do you do the Danube? We are going 9/3. We are worried about low water
Hi Joy – yes I am wondering too. We are travelling Budapest to Amsterdam in September so, I have everything crossed that the levels will be perfect 🙂
Anyone on a Viking River Cruise Basel to Amsterdam? Wondering about the water levels?
Is there anyone on the Basel to Amsterdam VIking now that can tell me how the water levels are?
We took the Amsterdam to Basel cruise July 12-19 and water levels were normal. They told us as water levels sink, certain areas of the Rhine will be impassible as soon as the following week. All in all great cruise and breathtaking scenery through the middle Rhine valley.
Travelled from Amsterdam to Budapest leaving Amsterdam 15th May on Emerald and completed the whole trip without issue. It was amazing, weather was about mid 20’s most days, pleasant to walk about and enjoy the lovely villages.
I decided that May would be the best time to travel as the river levels would be quite good after the winter and it proved correct.
Thank you Roberta for your updates on the water levels. We are cruising Budapest on Amsterdam the end of August so keeping a close eye on how the levels are affecting cruising. It does seem to be a day by day thing though.
Where did you swap ships. We are doing the same trip late August
The Viking Lif (Amsterdam to Bucharest) has had no problems with the water levels as the rains have been daily – light showers to 15-min downpours. We are approaching Budapest today (Aug 1) and the crew does not anticipate any trouble to the end. But then again, we are past the crucial Regensberg-Passau stretch.
We just did Budapest to Amsterdam and there was a stretch that too low so it impacted several days of our trip, we were bussed (5hours on bus) and had to switch boats. Still had a good vacation and they really worked hard to make it smooth, but that part wasn’t ideal.
Update – Sun July 30 – Vienna Austria
We made it past the point of no return – Regensburg to Passau. More water in the river than just the minimum depth needed. Melk and Krems were a breeze and we had good docking locations in both, with Viking offering several shuttles to City Center in Krems.
Today in Vienna – We docked a full 2 hours ahead of schedule. So far (1723 Vienna time) we have had two HUGE rain storms. Came down in buckets for a good 15 minutes each time. I think we will be alright for the rest of the trip to Bucharest, and anyone who started a cruise in Amsterdam or Bucharest in the last 7 days should have more than enough river depth to cruise through easily. If the rains do not keep up their daily appearance, no matter the volume, then it might be back to touch and go. I’d teach you all my rain dance if this was a video. Of course, you would also need Meg as a good luck charm.
Thanks for the update. Please keep us posted on the water levels when you are onboard the river cruise ship.
Our neighbors just got back from a Viking Danube cruise and had to disembark at Passau. They were then bused to another ship to continue. The passengers on the other ship did the same, basically just swapping ships.
Roberta,
I’m so glad it has rained for you. Hopefully by the time you get to Regensburg, the sky will be blue and you can wander around the town, as I think the cruise ships dock very close to the centre. Hopefully all good till you get to Passau.
CD – guess I am finding out that my friend was correct in a way, and that you are correct in a way. Viking does NOT always supply hourly buses from docking to city center. I contacted Viking time and time again asking for specifics. In Cologne. We were 1st docked a 45-min bus ride to town. The ship moved while we were in town on tours or doing your own thing, but you still needed to catch one of the buses to return to the new docking area which was still a good 15-min bus ride away from city center, in the middle of an industrial area, and not ON the Rhine or Main River itself. And we only learned of the docking locations the night before we hit Cologne.
For the Miltenberg docking, we docked in Freudenberg, a 15-min bus ride north, and there was only one bus to go there and one bus to return to the ship.
Bamberg – docked a 25-min bus ride away with only one bus to go back to the new docking location 10-mins away. Most of the passengers were at the bus pickup point 1 to 2 hours earlier than the scheduled pick up time – not convenient at all. Because the ship was on the move between the docking times, there could be no other shuttle buses arranged.
So if this is complaining, I am of that group. If Viking had been honest and forthcoming in answering my scheduling questions, I would not be AS upset. I could have planned my time accordingly, rather than be shocked that instead of being in Regensberg at 8:30a with time to do a self-tour in the morning after breakfast and then joining the included tour at 2p after lunch, with free time in Regensberg until 6p,.But we did not dock there until 12;30p – only finding that out the night before. It was a waste of my time to research things to do, to plan and print a routing, only to be disappointed.
I’m just stating the obvious. Viking should be upfront with a paying customer before a trip when asked a direct question.
Meg! You must have been our good luck charm.
Our Viking Program Director told us yesterday, that with the rains the area has been having, the home office has cleared us for a direct sailing – NO BUS TRANSFER! Yeaaaaaaaa!
And with the rains we had in Bamberg yesterday, all day, the rivers must be even higher.
GREAT NEWS! Our Viking Program Director told us yesterday, that with the rains the area has been having, the home office has cleared us for a direct sailing – NO BUS TRANSFER! Yeaaaaaaaa!
And with the rains we had in Bamberg yesterday, all day, the rivers must be even higher.
Viking needs to get their act together, it’s Americans who keep those River cruises floating. We have done several
Hi Roberta
Hopefully as you weren’t able to dock at Miltenberg, you maybe able to dock in Bamberg close to town and enjoy a bit of a walk around and not have 5 hours docked in middle of “nowhere”.
I guess the big test is coming up soon when you arrive in Passau.
Thanks for all your reporting. I’m very interested in how your cruise is going.
Have been watching the European weather and have my fingers crossed for you.
We did a trip from Amsterdam touring through the Netherlands and into Belgium with Avalon Waterways. It included a tour to Kuekenhof Gardens. It was excellent although be prepared as our weather was fairly cool. I think there’s less chance of low water levels in the spring.
In 2022 we did a river cruise in July with Scenic. It was exceptional with a number of excellent Signature experiences but we did have to change boats due to low water levels. However, the experience was painless . We were bused between ships and the crew handled the luggage transfer. Slightly disappointing not to cruise into Budapest, but we were bused in from where we’d docked, about an hour on the bus.
That was our first river cruise and it was a first rate experience.
Water levels have been good, but we are still on the Rhein. Yesterday, instead of being docked in Miltenberg, we were docked in Freudenberg – a 15-min bus ride away. Again, no explanation and there were no other Viking and/or other cruise ships docked in Miltenberg.
Today, unless you take one of their optional pay excursions, you are stuck on the ship a full 5-hours longer than those who took an optional tour, even the one that is IN Wurzburg. A total rip-off.
Bernard – I was sure hoping that this would not be the case, but you are correct. The lies, misinformation, concealment of information has really saddened this trip. I inquired numerous times to different Viking Reps – when and where do we dock so I can plan my day accordingly. Although I knew times would be approximate, I was NEVER told that unless you take one of their optional pay excursions, you would not be getting off the ship until hours later, thus eating up the time you have in a particular city. Also, chances are you will not dock close enough to walk to-and-from the ship to break up the time there, use the restroom, rest your tired feet and legs, etc. I have already commented on the Cologne disaster and today’s visit to Wurzburg had me in tears. If you took the Hiking the Hills PAID excursion, you were off and exploring at 8:30am and getting into Wurzburg a full 5 hours before the rest of us. I asked if I could hitch a ride to the starting point and NOT go on the tour – NO!
I guess the biggest disappointment is being LIED to. Do not lie to me and do not ignore me are my only two rules. I can handle NO and I can always work around what I find out. Also, it would have influenced my decision of what shore excursions to take and IF I would take Viking AT ALL. Maybe that’s their point – hide the bad. So sad. If you are booked for a Viking cruise, get out now. Rebook with River Cruise Advisors and DO take their advise, their suggested cruises, and more importantly, maybe ones that they will be on themselves.
new update – according to my fantastic cabin lady (housekeeper) Eva, they reported light rains in Amsterdam and parts of Germany. She said the crew has been told that this might be enough to keep us from changing ships. They are monitoring it daily. Fingers, toes and eyes are crossed.
Well here’s an interesting development. This was one of the news feeds that came up today and caught my attention – https://www.msn.com/en-us/travel/news/amsterdam-bans-cruise-ships-to-limit-visitors/ar-AA1e8Krs?ocid=msedgntp&cvid=37edc269667b4fc4823ec99f5a8ef33f&ei=8
Looks like Amsterdam is going to close their cruise port. The article did not clarify if this was only to LARGE ships, or ALL ships. The only thing I can say or add is the pot smoking is really prevalent and if you don’t like the smell, it’s sometimes overpowering. And it was wall-to-wall tourists until you got off the main streets.
As far as the cruise goes, it’s only day 3 and we hit Cologne today. Unfortunately, the Viking Lif had to dock a 45-min bus ride from the City Center. No real explanation was given. And when the ship caught up to us IN Cologne, it was not a walkable distance from CC to the ship, but Viking arranged bus shuttles – on the hour going INTO Cologne, on the half for the return to ship, from 2p until 5:30p being the last shuttle back.
Then we set sail again around 6:30p and not the expected 10p, but docking once again in Wesseling to pick up the folks who took the Optional Dinner w/Beer Excursion, who were bused from dinner to Wesseling.
All-in-all, I think this is going to be a “go-with-the-flow” trip because there’s not much you can do about it.
We’re planning a trip from Budapest to Amsterdam next May (2024). Does anyone have any reliable forecasting tools so we can make a decision this month, before we finalize our trip?
Hi Roberta
I have been monitoring your blogs for some months now and you always offer ideas and sound advice, for which I am very grateful.
Although this year I won’t be travelling till November and on the Seine, I am always interested on how the water levels are on the Amsterdam to Budapest trip, which is my favourite
Thank you again Roberta for your reports. I’d be very interested to see how your cruise goes.
Will also be cruising in July. Was scheduled to board the Viking Vidar on July 19th in Amsterdam. Just received an email from Viking – we will be boarding the Viking Lif instead. I have been tracking the Vidar for 2 months now and it looks like they can’t get past Passau. There’s a post below that mentioned they had to leave the ship Regensberg and bus to Passau. Looks like this is what will probably happen unless some of you know a good rain dance.
Viking Var June 30 docked at Passau. Next day 90 mins Bus to Regensburg for the day trip. Smooth cruise from there to Budapest. Lots of ships in Passau waiting it out. Levels varied day by day
Hi, Just finished a cruise with Travelmarvel from Amsterdam to Budapest. Low Water passed Nuremberg so we had our tours of Nuremberg and then carried on by coach to Passau and joined a sister ship, completely identical, we had the same cabin number etc. A very smooth transition and carried on to Budapest.
If you’re up to it, a lot of ships have bicycles you can take.
Hi Ray. Thanks for the update. Were water levels too low? Which cruise line? Did they do a ship swap?
We leave cruise on July 13 Amsterdam to Budapest on Viking. Any updates would be appreciated!
Could not cruise from
Passau to Regensburg
at very end of June 2023.
Thanks for that great up-to-the minute news. I sure hope things stay this way throughout the summer.
We just completed a Viking Budapest to Amsterdam cruise and water levels were perfect. No delays, no ship changes, no bussing! All was perfect.
Thx for sharing Mike!
We are on a Basel to Amsterdam Viking cruise right now. We did the Lake Como pre trip which was terrific and enjoyed a spectacular ride over the Alps to Basel on Friday, with a lunch stop in Lucerne. The Rhine water level is fine and the ship and crew are amazing! We dock in Strasbourg tomorrow and the only glitch is we can’t dock downtown due to construction on a pier or bridge, can’t remember which but I guess it’s going to be that way all season. Viking will be running shuttles all day to accommodate the passengers.
Hi
Just returned (27 may) from Amsterdam Budapest cruise with Amadeus. No water level problems or any “talk” of problems. Water levels in all rivers look to be “high” we had one small scrape under a bridge on the Main but that’s all. Weather brilliant with both warm (24) afternoons and cold mornings/nights (10).
Hope you enjoy your trip

Hi
Had dreadful experience. 2018 October (early). Amsterdam to Budapest with AP.
Glorified bus trip and 2 boats used, many alternative last minutes hotel stays, and long bus trips to new desitnations/hotel accom. Very little river cruising.
With great difficulty finally got a 30% refund. Crew did their very best, it was dealing with the company that left its mark, a traumatising and difficult time which we will never forget!
Thanks Sylvia! Good to hear! I was worried the water levels were dropping more quickly than last year. I realize a lot can change between now and mid July but hopeful our timing is right!
Exactly!
It is difficult to say! We did the same last year & although people on river cruises were complaining about hotels & being buses, Viking spoke person always said there were no problems… when there is outright lying it makes it difficult to make a sensible decision… as it turned out, if we had gone last year we probably would have changed ship once and bused for a few hours….. but with the misinformation we could not trust Viking… the sad part, practically criminal is they keep your money for a year, then increase the cost of the trip by 50% for the next year…
That is it, blame the customer!
We just returned from a Viking cruise Amsterdam to Budapest May 5-22, 2023. There were showers most days and water levels were high. We had to swap ships in Regensburg but Viking made the swap very easy. All in all a great cruise.
That’s Budapest, not Bucharest…
It’s a bit strange that we’re not seeing a lot of response by this time in the season! I’m hoping that rivers are flowing well!
Hi Craig,
Not travelling until November on the Seine, but nevertheless very interested in all rivers levels. Last year travelled from Budapest to Amsterdam in mid October and had no problems with water levels.
What have you found out, we are doing the same cruise Sept 12. Craig N
