Seine water levels in August

Right now a Seine cruise in August 2026 has a 1% chance of running into high water at the tightest bridges: low risk. This comes from the live forecast and is updated every morning.

August stays benign on the Seine; the river is at its lowest and the locks keep it navigable. Cruise disruption is close to unheard of.

August has hit high water in roughly 0% of the past thirty years on this river, 2th calmest of the twelve months. July and August run calmest on the Seine, March and February riskiest.

The last five Augusts, from the official record: 2025 clear · 2024 clear · 2023 clear · 2022 clear · 2021 clear. All five recent Augusts came through clear.

On the Seine the risk runs the other way: high water. Too little clearance under the Paris bridges pauses sailings and closes moorings. The river never dries out. It rises.
