Heating and cooling a home in Aneta
96% 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 Larimore 4sw, ND.

What the numbers mean for a garden, a free afternoon and a bad-weather day.

| Aneta, ND | −2° | 79° | 21" | 42" |
| Alexandria, MN | 1° | 80° | 27" | 46" |

| Kingsford, MI | 5° | 80° | 29" | 61" |
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 Aneta averaged 1.0° warmer than the 1900s. The biggest change is in January (+3.5°).
A smaller shift than in 75% 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 Aneta compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Aneta’s place among North Dakota’s.
