| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Chaplin, CT | 18° | 83° | 49" | 39" |
| Stroudsburg, PA | 18° | 84° | 50" | 42" |

| Manchester, MD | 22° | 84° | 47" | 34" |
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 Chaplin averaged 1.9° warmer than the 1900s. The biggest change is in December (+3.7°).
A bigger shift than in 83% 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.
