| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Washington, VT | 6° | 76° | 47" | 89" |
| Belfast, ME | 12° | 76° | 48" | 72" |

| Bradford, PA | 15° | 80° | 44" | 75" |
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 Washington averaged 1.6° warmer than the 1900s. The biggest change is in December (+3.9°).
A bigger shift than in 67% 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 Washington compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Washington’s place among Vermont’s.
