Months with highs of 62–84° and lows of 40° or more: February, March, April, October and November. 20 miles of trails are waiting.

| Canutillo, TX | 32° | 96° | 9" | 0.0" |
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 Rosedale averaged 2.0° warmer than the 1900s. The biggest change is in January (+2.7°).
A bigger shift than in 88% 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.
