Heating and cooling a home in Orange
97% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through May.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Grafton, NH.

Climates most like Orange’s, farther away
TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Orange, NH | 8° | 75° | 52" | 68" |
| Belfast, ME | 12° | 76° | 48" | 72" |
| Liberty, NY | 14° | 78° | 53" | 70" |
| Hazleton, PA | 16° | 78° | 51" | 42" |
| Sault Ste. Marie, MI | 8° | 76° | 37" | 120" |
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 Orange averaged 1.8° warmer than the 1900s. The biggest change is in December (+3.7°).
A bigger shift than in 79% 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 Orange compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Orange’s place among New Hampshire’s.
