Climates most like Austin’s, farther away
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 |
|---|---|---|---|---|
| Austin, IN | 23° | 87° | 48" | 12" |
| Hockessin, DE | 24° | 86° | 48" | 12" |
| Kennett Square, PA | 23° | 86° | 48" | 12" |
| Mount Vernon, IL | 23° | 87° | 46" | 10" |
| Millville, NJ | 25° | 87° | 46" | 12" |
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 1.2° warmer than the 1900s. The biggest change is in December (+2.2°).
A smaller shift than in 64% 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 Indiana’s.
