Climates most like Kohler’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 |
|---|---|---|---|---|
| Kohler, WI | 14° | 80° | 32" | 45" |
| Le Roy, NY | 17° | 80° | 35" | 52" |
| Alpena, MI | 14° | 78° | 31" | 59" |
| Colchester, VT | 10° | 81° | 38" | 50" |
| Lakeville, MN | 7° | 82° | 33" | 41" |
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 Kohler averaged 1.6° warmer than the 1900s. The biggest change is in December (+3.3°).
A bigger shift than in 63% 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.
