| Littleton, NH | 6° | 80° | 40" | 68" |
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 Washburn averaged 1.6° warmer than the 1900s. The biggest change is in January (+3.4°).
A bigger shift than in 65% of U.S. towns.
