| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Alvin, WI | 3° | 77° | 32" | 67" |
| Cloquet, MN | 0° | 78° | 31" | 71" |

| Littleton, NH | 6° | 80° | 40" | 68" |
| St. Johnsbury, VT | 5° | 79° | 41" | 87" |
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 Alvin averaged 1.7° warmer than the 1900s. The biggest change is in December (+3.3°).
A bigger shift than in 72% 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.
