Rhine water levels in June

June 2027 currently carries a 13% chance of low water trouble on the Rhine at its shallowest stretch: moderate. Until the live forecast reaches June, about seven months ahead, this is the thirty-year record.

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.

Across thirty years of records, June brought low water to the Rhine in about 13% of years, the calmest of the twelve months. The calmest months here are June and May; the most exposed are August and September.

The last five Junes, from the official record: 2026 13 low water days · 2025 clear · 2024 clear · 2023 3 low water days · 2022 clear. Of the last five, 2026 and 2023 hit low water; 2025, 2024 and 2022 sailed clear.

Affected rarely means canceled. On the Rhine it usually means a ship swap, a rerouted day, or a stretch covered by bus, almost always at the gorge between Rüdesheim and Koblenz. That shallow reach decides every Amsterdam to Basel itinerary.
