Heating and cooling a home in Laramie
99% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from September 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 Laramie Rgnl Airport.
Living with Laramie’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
102 frost-free days in zone 4a. The last frost comes by Jun 2 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 15.

Warmer than it used to be
The last 30 years in Laramie averaged 1.9° warmer than the 1900s. The biggest change is in March (+4.0°).
A bigger shift than in 85% 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.
