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 Berlin averaged 1.7° warmer than the 1900s. The biggest change is in December (+4.1°).
A bigger shift than in 73% 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.
How Berlin compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Berlin’s place among New Hampshire’s.
