Weather extremes

How extreme does Greenville's weather get?

The hottest, coldest, wettest and snowiest days Greenville 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 (1971–2024), from the Greenville Kgvl Radio station 3 km away. Updated through October 2024 — 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 Greenville has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
115°F Aug 20, 2006

That is about 17°F hotter than a normal August afternoon in Greenville (typical high near 98°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.

Greenville's record heat sits well above even a hot day for the season — August's 115°F is about 17°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, Greenville's warmest days reach the high 90s°F and its coldest nights drop to the low 30s°F. But across the record it has gone as high as 115°F and as low as −3°F. A single day has delivered over 7 inches of rain or close to 5 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
