Climates most like Kelly’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 |
|---|---|---|---|---|
| Kelly, WI | 4° | 79° | 32" | 74" |
| Beekmantown, NY | 9° | 80° | 35" | 80" |
| St. Joseph, MN | 3° | 81° | 30" | 57" |
| Littleton, NH | 6° | 80° | 40" | 68" |
| St. Johnsbury, VT | 5° | 80° | 40" | 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 Kelly averaged 1.6° warmer than the 1900s. The biggest change is in December (+3.4°).
A bigger 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.
