The hottest, coldest, wettest and snowiest days Bissau has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 32 years of daily weather observations (1993–present), from the Bissau Oswaldo Vieira Intl station 7 km away. Updated through August 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

In plain terms
Across the record, Bissau has reached as high as 111°F and as low as 50°F. A single day has delivered over 11 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
