Warmer than it used to be
The last 30 years in Coolidge averaged 1.1° warmer than the 1900s. The biggest change is in March (+2.9°).
A smaller shift than in 72% 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.
