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 Glendale averaged 2.6° warmer than the 1900s. The biggest change is in January (+3.5°).
A bigger shift than in all but 32 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. In a city of 187,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
