How extreme does Saint-Martin-d'Hères's weather get?

The hottest, coldest, wettest and snowiest days Saint-Martin-d'Hères has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 20 years of daily weather observations (2005–present), from the Grenonble Lvd station 8 km away. Updated through January 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.
