Danube and Rhine Water Levels Today: Which River Cruises Are Cancelled?

Danube and Rhine Water Levels

Live status for the 2026 low water season on Europe's rivers, updated as conditions change.

Last updated: 30 August 2026. Water levels, cruise line alerts and forecasts checked against sources dated 26 to 28 August.

No, Danube and Rhine river cruises have not stopped. As of 30 August 2026 most lines are still sailing, but with changes: ship swaps, coach transfers, moved embarkation ports and hotel nights. Outright cancellation is the exception, not the rule. Riviera Travel, Avalon Waterways, Tauck, Nicko Cruises and Viva Cruises have cancelled selected departures. Viking, AmaWaterways, Scenic, Emerald and Uniworld are mostly rerouting instead.

So the honest answer to "is my cruise cancelled" is almost certainly no. The harder question is whether the holiday you booked is the holiday you'll get, and that one depends entirely on which stretch of river your ship needs to pass.

Current status at a glance

• Rhine at Kaub: about 66cm on 26 August, recovered from a record 6cm on 17 August. The official low water reference at Kaub is 77cm.

• Upper Danube at Pfelling: about 237cm on 26 August, up from 194cm on 17 August. The regulated low water reference is 290cm. Navigation between Regensburg and Passau remains closed.

• Danube at Budapest: 59cm on the evening of 25 August, forecast to fall to roughly 37 to 41cm by 30 August. The Danube Commission low water reference is 93cm.

• Reopened: stretches near Dürnstein and Vienna, after rain around 22 to 23 August.

• Still closed or affected: Regensburg to Passau, Bratislava to Budapest, Cologne to Koblenz, Rüdesheim to Mainz, the Mannheim area.

• Rainfall outlook to about 10 September: roughly 72 per cent below normal in the Rhine's Alpine headwaters, roughly 60 per cent below normal in the Inn valley and Bavarian Danube.

  
  

Is my Danube or Rhine cruise cancelled right now?

Probably not, but your itinerary may well have changed.

The industry's clear preference this summer has been to operate an altered holiday rather than cancel one. Viking, AmaWaterways, Scenic, Emerald, Uniworld and APT are all still running large parts of their programmes with modifications. The lines that have shown most willingness to cancel outright are Riviera Travel, Avalon Waterways and Tauck.

Two identical departures a week apart can end up completely different, because what matters is where your specific ship happens to be when a shallow reach closes. That's why lines are leaving final decisions until close to sailing date, and why a company wide statement on a website only tells you so much.

If you're sailing in the next fortnight, expect a call or an email in the seven days before departure. If you haven't had one and you're inside a week, chase it.

What are the water levels today?

Gauge readings are the number everyone quotes, so it's worth knowing what they actually are. A gauge height is a measurement at one fixed point, not the depth of water under your ship, and readings from different gauges cannot be compared with each other. Whether a vessel can pass depends on its draft, how heavily it's loaded, the navigable channel and the captain's judgement on the day.

Gauge	Latest reading	Reference level	What it means
Rhine at Kaub	About 66cm, 26 Aug	77cm low water reference	Big recovery from 6cm on 17 Aug, still below reference. Forecast flat in the low 60s to 28 Aug.
Rhine at Cologne	1.14m, 26 Aug	n/a	Major improvement on the 46 to 47cm readings around 17 Aug. Cologne to Koblenz still listed as affected.
Upper Danube at Pfelling	About 237cm, 26 Aug	290cm regulated low water	Peaked near 287cm on 22 to 23 Aug then slipped back. Regensburg to Passau closed.
Danube at Budapest	59cm, 25 Aug	93cm low water reference	Forecast falling to 37 to 41cm by 29 to 30 Aug. Bratislava to Budapest closed.
Main and Main to Danube Canal	Controlled, but approaches restricted	n/a	The canal itself is lock managed. The problem is reaching it, or continuing past it.
Seine, Rhône, Saône, Douro	Normal operations	n/a	No widespread low water disruption reported on the main cruise programmes.

Kaub is the number the trade watches because it's the first place a shallow water limit gets hit. It sits in the Middle Rhine Gorge between Rüdesheim and Koblenz, the castle stretch everyone books the cruise for. When people say "the Rhine is closed," they nearly always mean Kaub.

For context on how far outside normal this year is: Bloomberg reported that Kaub's 6cm reading on 17 August was the lowest since record keeping began in 1880. The previous low in German government reference data was 25cm, set in October 2018. At Pfelling, the 194cm reading on 17 August went below the previous benchmark low of 221cm from August 2022.

Which stretches are actually closed?

Scenic has published the clearest operating map of any line, and as of 26 August it listed navigation as closed between Regensburg and Passau near Pfelling, and between Bratislava and Budapest. On the Rhine, it listed Cologne to Koblenz, Rüdesheim to Mainz and the Mannheim area as affected, with some sections unsuitable for navigation.

The practical read on that: a classic Amsterdam to Basel Rhine itinerary is possible but not guaranteed end to end. A Danube itinerary that runs the full Nuremberg or Passau to Budapest route has two separate problem reaches to clear, which is why so many Danube guests this summer have ended up on coaches.

Further downstream, Romania has had its own version of this. The Danube there fell to roughly 1,500 cubic metres per second in early August, around a third of a typical July flow, which forced authorities to shut a reactor unit at the Cernavoda nuclear plant. That's outside the main cruise programmes but it tells you the scale of the drought.

What is each cruise line doing?

Line	Current approach
Viking	Sister ship swaps are the main tool. Guests go off on an excursion, luggage moves to an identical ship on the other side of the shallow reach, often into the same numbered stateroom. Long coach transfers still reported on some departures.
AmaWaterways	Rerouting rather than cancelling. Changed ports, altered embarkation and disembarkation, motorcoach transfers, reversed itineraries. One recent AmaSofia sailing stopped at Melk with guests continuing by coach.
Scenic	Sister ships, changed embarkation points, coaches and hotel nights. Guests on affected departures through 10 September should have had an initial notice, with a further update about a week before sailing.
Emerald Cruises	Same Scenic Group contingency system. Options can include an altered itinerary, rebooking or future travel arrangements depending on the departure.
Riviera Travel	The most conservative move so far. On 25 August it paused new sales of Rhine and Danube cruises through 13 September. Existing departures are not blanket cancelled. It had previously reported 10 cancellations and six materially changed departures.
Avalon Waterways	Affected guests get a choice: move to another Avalon cruise, apply the value to a Globus or Cosmos land tour, or take a full refund. At least three named Danube departures cancelled.
Tauck	Has cancelled selected departures where it judged conditions too disruptive. One passenger with a cancelled Rhine and Moselle sailing reported a full refund within two days.
Uniworld	Says the large majority of sailings operate as planned, but its port pages show heavy tactical changes: a 23 August embarkation moved from Nuremberg to Passau, another sailing starting in a Budapest hotel, and the S.S. Antoinette and S.S. Elisabeth swapped for 30 August Rhine departures.
APT and Travelmarvel	Continuing to operate with adjustments. Guests advised to expect direct contact about a week before departure.
Nicko Cruises and Viva Cruises	The largest cancellation numbers reported. According to a Cleveland Research note covered by Seatrade Cruise News, Nicko has cancelled around 20 sailings, with some cancellations at Viva too.

Riviera's stop sale is the one worth paying attention to, because it's a commercial signal rather than an operational one.

When an operator would rather stop taking money than risk delivering a coach tour, that tells you how uncertain the next fortnight looks.

Will the rivers recover in September?

Partly, and not reliably.

Rain did arrive around 22 to 23 August and it made a real difference on the Rhine. Kaub climbing roughly 60cm in nine days genuinely improved operating margins. But the underlying catchments are still dry, and the forecast rainfall through to about 10 September is far below normal in both the Rhine's Alpine headwaters and the Bavarian Danube.

Budapest is the clearest warning. It's forecast to keep falling through 30 August, and any recovery there depends on new rain upstream in Austria and Slovakia working its way down, which lags the rainfall itself by several days.

One analyst view, from Cleveland Research's is that the worst may be over by mid September. That's a reasonable read, but it's a forecast, not a guarantee. The honest position is that conditions have eased in places rather than ended.

If you're booked for late September or October, the picture genuinely is better than August. If you're booked for the next two weeks, plan for a changed holiday.

What are you owed if your itinerary changes?

This is where most people get a nasty surprise, so read this bit properly.

If the cruise still operates and the line changes the route, almost every operator treats that as an itinerary modification rather than a cancellation. That usually means no refund. Most travel insurance policies take the same view, because the holiday went ahead. Some lines offer onboard credit or partial goodwill compensation, but it is discretionary and varies wildly between operators and even between departures.

If the line cancels, you get a refund or the choice of an alternative. Tauck and Avalon have both been paying out on cancelled sailings.

UK bookings have a stronger position than most people realise. Under the Package Travel and Linked Travel Arrangements Regulations 2018, if an organiser makes a significant change to a main element of your package before departure, you can accept it, take an alternative, or cancel for a full refund. What counts as "significant" is the argument, and swapping three ports for coach days is exactly the kind of change that gets contested. I'm not a lawyer and this isn't legal advice, but if you're UK booked and your itinerary has been substantially rewritten, it is worth putting that question to your operator in writing rather than accepting a hundred pounds of onboard credit.

Three practical things worth doing:

1. Get every change in writing. Verbal notice from a cruise director is not a record.

2. Flag mobility, dietary or independently booked flight issues immediately. Ask specifically how a ship swap or a coach day would work for you. Lines can accommodate this if they know early.

3. Do not cancel yourself before asking. Cancelling voluntarily usually forfeits your money. Making the operator declare the change is what protects you.

   
   

How do I check the water level myself before I sail?

You don't need a cruise line to tell you what the river is doing. The gauges are public.

• Rhine at Kaub and Cologne: Germany's PEGELONLINE service, run by the federal waterways administration, publishes live readings every 30 minutes.

• Upper Danube at Pfelling: Germany's ELWIS system, which also holds the historic low water records.

• Danube at Budapest and downstream: the Danube FIS portal.

• 14 day outlook: the BfG ensemble forecast for the Rhine. Treat anything beyond about seven days as a rough steer rather than a plan.

Two rules for reading them. First, compare a gauge only against its own reference level, never against another gauge. Second, a rising number does not mean your ship can pass. A gauge is a height at a point, and the channel your ship needs is a different thing entirely.

Frequently asked questions

Are Danube river cruises cancelled today?

Not as a whole. As of 30 August 2026 most operators are still sailing the Danube with modified itineraries. Riviera Travel, Avalon Waterways, Tauck, Nicko Cruises and Viva Cruises have cancelled selected individual departures. Navigation is closed between Regensburg and Passau and between Bratislava and Budapest, so itineraries crossing those reaches are the most likely to change.

What is the Rhine water level today for cruise ships?

The Kaub gauge, the Middle Rhine bottleneck the industry watches, read about 66cm on 26 August 2026, recovered from a record 6cm on 17 August but still below the 77cm low water reference. Cologne was at 1.14m. Both readings improved substantially through late August.

Will I get a refund if my river cruise itinerary changes?

Usually not a full one. Most lines treat a changed route as an itinerary modification rather than a cancellation, and most travel insurance follows the same logic. If the line cancels the sailing outright you get a refund or an alternative. UK bookings may have additional rights under the Package Travel Regulations if the change is significant.

Does low water mean I'll be on a bus all week?

Not usually, but it happens. The most common outcome is a ship swap, where you move to an identical sister ship on the other side of the shallow section, often into the same cabin number. Coach transfers tend to bridge a single stretch. Some passengers this summer have reported much heavier coach itineraries, including one 12 hour transfer.

Which cruise line handles low water best?

Viking and AmaWaterways have the strongest positions structurally, because large fleets of near identical sister ships make swaps straightforward. Scenic publishes the clearest information on which stretches are closed. Riviera and Tauck are more likely to cancel rather than deliver a compromised holiday, which some guests prefer.

Should I book a Rhine or Danube cruise for 2027?

Yes, if you want one. Current conditions tell you nothing about a sailing 12 months out. Spring and early summer are historically the most reliable window because Alpine snowmelt keeps the upper rivers topped up, while late summer and autumn carry the most low water risk. 2026 has been an unusually dry year, not a new permanent state.

Can my travel insurance cover a low water itinerary change?

Rarely. Standard policies cover cancellation and curtailment, not a holiday that went ahead in altered form. Some premium or specialist river cruise policies include disruption cover. Check the wording for "itinerary change" specifically before you assume you're covered.

When will the Rhine and Danube go back to normal?

No firm date. The Rhine has recovered significantly from its mid August record low, and the Vienna area of the Danube has reopened, but rainfall forecasts through early September are well below normal in both catchments. One industry analyst expects the worst to be over by mid September. Recovery depends on sustained rain, not a single storm.

So where does that leave you? If you're booked in the next two weeks, assume something will change and get it in writing when it does. If you're booked for October or later, the trend is going your way. And if you're thinking about 2027, book it, because this summer says nothing about next spring.

I'll keep this page updated as the gauges move and the lines announce changes. If your own sailing has been altered, drop a comment below with the line and the date, because those real reports are more useful to the next person reading this than any press release.
