Rhine water levels in March

Right now a Rhine cruise in March 2027 has a 50% chance of running into low water at the shallowest stretch: high risk. It reflects the thirty-year record for March; the live forecast reaches this month about seven months out.

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.

Across thirty years of records, March brought low water to the Rhine in about 50% of years, 9th calmest of the twelve months. The calmest months here are June and May; the most exposed are August and September.

The last five Marchs, from the official record: 2026 clear · 2025 18 low water days · 2024 clear · 2023 10 low water days · 2022 24 low water days. Recent Marchs split: 2026 and 2024 stayed clear, while 2025, 2023 and 2022 hit low water.

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.
