Santo António's weather extremes

The hottest, coldest, wettest and snowiest days Santo António has recorded — the outer limits of what its weather can do. This station's daily record ended in 2022, so these are historical extremes from that period, not records updated to today.

Based on 31 years of daily weather observations (1991–2022), from the Principe station 3 km away. Updated through October 2022 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.
