Heating and cooling a home in Antwerp
96% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through April.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Gouverneur 3 Nw, NY.

| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Antwerp, NY | 9° | 80° | 41" | 92" |
| Winslow, ME | 9° | 80° | 44" | 86" |

| Adams, MA | 13° | 81° | 45" | 77" |
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 Antwerp averaged 1.8° warmer than the 1900s. The biggest change is in December (+4.0°).
A bigger shift than in 77% 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 Antwerp compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Antwerp’s place among New York’s.
