Rhine water levels in July

The current figure for July 2027 on the Rhine is 20%: the chance a sailing runs into low water at the shallowest stretch. In short, moderate. Until the live forecast reaches July, about seven months ahead, this is the thirty-year record.

By July the melt is tapering and the rivers begin their slow summer decline. Most years hold up; a hot, dry early summer shows first in the shallow reaches.

The long record puts July at low water in about 20% of years, 3th calmest of the twelve months on the Rhine. Book June or May for the calmest water; August and September carry the most risk.

The last five Julys, from the official record: 2026 31 low water days · 2025 clear · 2024 clear · 2023 3 low water days · 2022 16 low water days. Year to year it swings: 2026, 2023 and 2022 met low water in July, and 2025 and 2024 stayed 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.
