The hottest, coldest, wettest and snowiest days Suncheon has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 16 years of daily weather observations (2009–present), from the Suncheon station 13 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 Suncheon

looks like.

In plain terms
Across the record, Suncheon has reached as high as 100°F and as low as 3°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.
