Seine water levels in August

Right now a Seine cruise in August 2027 has a 100% chance of sailing as planned past the tightest bridges: low risk. It reflects the thirty-year record for August; the live forecast reaches this month about seven months out.

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.

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 gone without high water in roughly 100% of the past thirty years on this river, 3th calmest of the twelve months. September and July run calmest on the Seine; March and February reward flexible plans.

The last five Augusts, from the official record: 2026 clear · 2025 clear · 2024 clear · 2023 clear · 2022 clear. All five recent Augusts came through clear.
