Climates most like Geneva’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 |
|---|---|---|---|---|
| Geneva, WA | 34° | 72° | 57" | 3.4" |
| Fortuna, CA | 42° | 70° | 55" | 0.7" |

| Nantucket, MA | 26° | 76° | 44" | 25" |
| Boone, NC | 24° | 79° | 58" | 26" |
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 Geneva averaged 1.4° warmer than the 1900s. The biggest change is in January (+2.9°).
A bigger shift than in 53% 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.
