95% 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 Saint Johnsbury, VT.

Climates most like Concord’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 |
|---|---|---|---|---|
| Concord, VT | 5° | 79° | 42" | 68" |
| Old Town, ME | 9° | 80° | 43" | 75" |
| Canton, NY | 8° | 80° | 39" | 77" |
| Stewartville, MN | 6° | 81° | 36" | 53" |
| Rib Mountain, WI | 6° | 80° | 33" | 64" |
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 Concord averaged 1.5° warmer than the 1900s. The biggest change is in December (+3.8°).
A bigger shift than in 60% 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.
