Rhine water levels in October

October 2026 currently carries a 66% chance of low water trouble on the Rhine at its shallowest stretch: high risk. It comes from the live forecast, which updates each morning.

October swings widest: if autumn rain arrives, the rivers recover fast; if it holds off, the summer drawdown deepens. The gap between good and bad Octobers is the largest of the year.

Across thirty years of records, October brought low water to the Rhine in about 47% of years, 10th calmest of the twelve months. The calmest months here are June and May; the most exposed are August and September.

The last five Octobers, from the official record: 2025 3 low water days · 2024 clear · 2023 15 low water days · 2022 clear · 2021 4 low water days. Of the last five, 2025, 2023 and 2021 hit low water; 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.
