| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Whitney, NV | 38° | 107° | 4" | 0.2" |
| Maricopa, AZ | 39° | 106° | 7" | 0.0" |

| Monahans, TX | 30° | 98° | 12" | 0.7" |
| Carlsbad, NM | 29° | 97° | 13" | 2.7" |
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 Whitney averaged 1.8° warmer than the 1900s. The biggest change is in January (+2.8°).
A bigger shift than in 80% 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.
