Seine water levels in July

July 2027 currently carries a 0% chance of high water trouble on the Seine at its tightest bridges: low risk. Until the live forecast reaches July, about seven months ahead, this is the thirty-year record.

July is the Seine's calmest water. The locks keep depth, and summer rain rarely comes fast enough to threaten clearance.

Across thirty years of records, July brought high water to the Seine in about 0% of years, the calmest of the twelve months. The calmest months here are July and August; the most exposed are March and February.

The last five Julys, from the official record: 2026 clear · 2025 clear · 2024 clear · 2023 clear · 2022 clear. None of the last five Julys hit high water.

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.
