| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Byron, GA | 35° | 92° | 48" | 0.0" |
| Darlington, SC | 34° | 92° | 47" | 0.0" |

| Helena-West Helena, AR | 33° | 91° | 52" | 0.3" |
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 Byron averaged 0.7° warmer than the 1900s. The biggest change is in December (+1.7°).
A smaller shift than in 92% 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.
