Seine water levels in March

For March 2027 the Seine stands at 40% high water risk at its tightest bridges: elevated. It reflects the thirty-year record for March; the live forecast reaches this month about seven months out.

March is historically the Seine's most exposed month: winter's accumulated rain meets spring storms, and clearance under the Paris bridges gets tightest.

The long record puts March at high water in about 40% of years, the riskiest of the twelve months on the Seine. Book July or August for the calmest water; March and February carry the most risk.

The last five Marchs, from the official record: 2026 3 high water days · 2025 clear · 2024 21 high water days · 2023 clear · 2022 clear. 2025, 2023 and 2022 came through March clear; 2026 and 2024 did not.

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.
