Danube water levels in March
The current figure for March 2027 on the Danube is 53%: the chance a sailing runs into low water at the shallowest stretch. In short, high risk. Until the live forecast reaches March, about seven months ahead, this is the thirty-year record.
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 puts March at low water in about 53% of years, 9th calmest of the twelve months on the Danube. Book May or April for the calmest water; August and September carry the most risk.
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.
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.
