How extreme does Magdalena Contreras's weather get?

The hottest, coldest, wettest and snowiest days Magdalena Contreras has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1973–present), from the Mexico City station 8 km away. Updated through May 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.
