“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Gantt
Gantt gets 50 inches of rain and melted snow a year. August is the wettest month and October the driest. Rain or snow falls on about 117 days a year.
About 250 frost-free days a year
In half of years the last 32° night comes by March 16 and the first one by November 20. That leaves about 250 frost-free days for gardens, longer than 90% of U.S. towns.
Heating and cooling a home in Gantt
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Gantt, 57% of that work is heating and 43% is cooling.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
Gantt and its neighbors
Gantt borders 2 towns with climate data. January nights across them vary by 0.0°. Greenville has the coldest January nights (33°) and Dunean the hottest July afternoons (89°). Gantt’s January low is 33° and its July high 90°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Gantt compares
Compared with every U.S. town and city on TownTapestry, each counted once.
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°). The shift is larger than in 54% of U.S. towns.

How much a month can swing
A normal is an average, and real years wander around it. December swings the most: between 1991 and 2020 its average temperature ranged from 36° to 55°. July is the most reliable, staying within 7°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Gantt itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Greer, SC (12 mi, snow) and Greenville Dwtn Airport, SC (5 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
