Climate & Weather in Greenville
Greenville has a genuine, real four-season humid subtropical climate distinct from coastal South Carolina: hot, humid summers averaging around 86°F, mild (not cold) winters ranging roughly 33-53°F, only about 3 inches of snow a year, and roughly 220 sunny days annually -- shaped by the city's Blue Ridge-foothills elevation and inland position.

Greenville summers average around 86°F for daily highs, with real humidity consistent with its humid subtropical classification -- broadly similar to much of the Southeast, though the city's foothills elevation offers some real, if modest, relief compared to lower-elevation Piedmont or coastal SC cities.
Winters: Genuinely Mild, Not Cold
December-through-February temperatures range roughly 33.3°F to 52.7°F -- mild winters with occasional nights near or just below freezing, but nothing resembling the cold winters of this dataset's Northern or mountain-West markets. Snowfall averages only about 3 inches a year, rare and mostly confined to December and January -- a real, genuine four-season climate, but one where snow is an occasional event rather than a seasonal expectation.
Rainfall: A Real, Distributed Annual Total
Greenville receives about 46 inches of rain annually, ranging from a September low of about 1.57 inches to a December high of about 4.06 inches -- rainfall is distributed across the year rather than concentrated in one narrow wet season, feeding the region's real flash-flood risk along local waterways discussed on the flood-hurricane-risk page.
A Genuinely Distinct Climate from Coastal South Carolina
Greenville's Blue Ridge-foothills elevation and inland position give it a real four-season climate genuinely distinct from Charleston's or Myrtle Beach's coastal, hurricane-exposed subtropical climate -- more seasonal temperature variation, real (if light) winter snow, and no hurricane season to plan around, at the cost of somewhat less mild winter and somewhat more humid summer weather than the immediate coast.
Key takeaways
- Humid subtropical climate: summer highs average around 86°F, with real, seasonal humidity.
- Winters are genuinely mild (33-53°F range, Dec-Feb) rather than cold, with only about 3 inches of snow a year, mostly December-January.
- Annual rainfall averages about 46 inches, distributed across the year (September low ~1.57", December high ~4.06").
- About 220 sunny days per year.
- Greenville's Blue Ridge-foothills climate is genuinely distinct from coastal South Carolina's -- more seasonal variation and no hurricane season, in exchange for less coastal mildness.
