Danube water levels in June

Right now a Danube cruise in June 2027 has a 17% chance of running into low water at the shallowest stretch: moderate. It reflects the thirty-year record for June; the live forecast reaches this month about seven months out.

June still runs on melt from the high Alps, and the rivers stay full. Historically it is the most dependable month of the cruise year.

The long record puts June at low water in about 17% of years, 3th 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 Junes, from the official record: 2026 11 low water days · 2025 clear · 2024 clear · 2023 4 low water days · 2022 clear. Recent Junes split: 2025, 2024 and 2022 stayed clear, while 2026 and 2023 hit low water.

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.
