Danube water levels in March

The current figure for March 2027 on the Danube is 71%: the chance a sailing goes ahead as planned, without low water interfering. In short, elevated. It comes from the live forecast, which updates each 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.

March opens the melt. The first warm spells send Alpine water down and levels start to climb; an early wet spring can briefly push the other way, toward high water.

The long record has March running as planned in about 47% of years, 6th calmest of the twelve months on the Danube. Book May or April for the calmest water; September and October are the months to check before you commit.

The last five Marchs, from the official record: 2026 6 low water days · 2025 10 low water days · 2024 clear · 2023 6 low water days · 2022 13 low water days. Year to year it swings: 2026, 2025, 2023 and 2022 met low water in March, and 2024 stayed clear.
