Danube water levels in April

For April 2027 the Danube shows a 87% chance a cruise runs as planned: moderate. This comes from the live forecast and is updated every morning.

Affected rarely means canceled. On the Danube it means ship swaps or bus days on the shallow reach between Straubing and Vilshofen and through the Wachau valley.

April rides the strengthening snowmelt. The mountains release winter's storage week by week, and levels build toward their early-summer best.

Across thirty years of records, April ran as planned on the Danube in about 93% of years, 2th calmest of the twelve months. The calmest months here are May and April; December and January lean hardest on the rain.

The last five Aprils, from the official record: 2026 clear · 2025 2 low water days · 2024 clear · 2023 clear · 2022 clear. 2026, 2024, 2023 and 2022 came through April clear; 2025 did not.
