The hottest, coldest, wettest and snowiest days Grenoble 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 12 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.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Grenoble
has recorded — each shown against what a normal day that time of year
looks like.

In plain terms
Across the record, Grenoble has reached as high as 102°F and as low as 2°F. A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
