The hottest, coldest, wettest and snowiest days Sunyani 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 Sunyani station 2 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
The hottest, coldest, wettest and snowiest single days Sunyani

looks like.

In plain terms
Across the record, Sunyani has reached as high as 111°F and as low as 48°F. A single day has delivered over 17 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
