Heating and cooling a home in Bisbee
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 Rolette 3se, ND.
Living with Bisbee’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
120 frost-free days in zone 3b. The last frost comes by May 22 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Sep 20.
Months with highs of 62–84° and lows of 40° or more: June, July, August and September.

Every town next door is within a degree of Bisbee in January and July, closer than the 5 km grid can tell apart. Tap a town to see its climate.
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 Bisbee averaged 1.6° warmer than the 1900s. The biggest change is in January (+4.5°).
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.
How Bisbee compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Bisbee’s place among North Dakota’s.
