Compared with towns across the U.S., with Gantt’s place in South Carolina beside it.
What a year in Gantt feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 250 frost-free days a year
In half of years the last 32° night comes by March 16 and the first by November 20. Day counts come from NOAA’s station at Greenville, SC, 4 miles from the town’s center, at about the same height; frost dates and degree days from Greenville Dwtn Airport, 5 miles away.
The 2023 USDA map puts Gantt’s center in zone 8a: the coldest night of a typical winter, averaged over 1991–2020, reaches about 14°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Gantt
57% of the work is heating. Months averaging under 55° run from November through March.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Greenville Dwtn Airport.
Living with Gantt’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
250 frost-free days in zone 8a. The last frost comes by Mar 16 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 20.
Months with highs of 62–84° and lows of 40° or more: March, April, May, September, October and November. 1.6 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Gantt from natural hazards, river flooding is the largest share (51%); heat waves, cold waves, winter storms and ice storms together are 16%. Normals are averages; the hazards page covers the extremes.

Climates most like Gantt’s, farther away
TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Gantt, SC | 33° | 90° | 50" | 3.9" |
| Dallas, GA | 32° | 89° | 51" | 3.8" |
| Tarboro, NC | 31° | 90° | 49" | 4.8" |
| Carrollton, VA | 32° | 89° | 49" | 2.7" |
| Blytheville, AR | 31° | 90° | 50" | 2.9" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Gantt averaged 1.3° warmer than the 1900s. The biggest change is in December (+2.4°).
A smaller shift than in 56% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
How Gantt compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Gantt’s place among South Carolina’s.
