Heating and cooling a home in Moscow
98% 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 Long Falls Dam, ME.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Moscow, ME | 6° | 75° | 48" | 109" |
| Harrietstown, NY | 5° | 75° | 46" | 104" |

| Minocqua, WI | 3° | 77° | 33" | 99" |
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 Moscow averaged 1.6° warmer than the 1900s. The biggest change is in December (+4.1°).
A bigger shift than in 65% 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.
