How extreme does Koronadal's weather get?

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

Based on 50+ years of daily weather observations (1971–present), from the Gen. Santos station 57 km away. Updated through June 2026 — 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 Koronadal has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day

102°F Apr 15, 1988

That is about 8°F hotter than a normal April afternoon in Koronadal (typical high near 94°F).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Koronadal's record heat sits well above even a hot day for the season — April's 102°F is about 8°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Koronadal's warmest days reach the mid-90s°F and its coldest nights drop to the low 70s°F. But across the record it has gone as high as 102°F and as low as 28°F. A single day has delivered over 7 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.

Methodology & sources

Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 11 years of daily observations at Gen. Santos, a weather station, about 57 km from the city centre. The underlying daily records come from NOAA's global station network.
