| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Austin, PA | 16° | 81° | 44" | 39" |
| Durham, NH | 16° | 81° | 47" | 39" |

| Aurora, OH | 19° | 82° | 42" | 45" |
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 Austin averaged 0.7° warmer than the 1900s. The biggest change is in December (+2.2°).
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.
How Austin compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Austin’s place among Pennsylvania’s.
