Warmer than it used to be
The last 30 years in Boca Raton averaged 1.8° warmer than the 1900s. The biggest change is in February (+2.4°).
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. In a city of 102,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
