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 |
|---|---|---|---|---|
| Gainesville, VA | 25° | 87° | 43" | 20" |
| Overland, MO | 23° | 88° | 42" | 17" |

| Cincinnati, OH | 23° | 87° | 44" | 16" |
| Palmyra, NJ | 25° | 88° | 47" | 22" |
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 Gainesville averaged 1.8° warmer than the 1900s. The biggest change is in December (+3.1°).
A bigger shift than in 77% 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 Gainesville compares
