How extreme does Sumbawanga's weather get?

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

Based on 34 years of daily weather observations (1991–present), from the Sumbawanga station 1 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.
