Graph showing how much cooler or warmer than average it was in Charlotte, NC in February 2025. The graph also marks the date when the first signs of spring appear (also known as 'first leaf' or 'leaf out') on average (February 16), as well as when it occurred this year (February 11). Warmer than average temperatures led to spring leaf out arriving as much as five days early.
