Heating and cooling a home in Experiment
59% of the work is heating. Months averaging under 55° run from November through March.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Experiment, GA.
Living with Experiment’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
239 frost-free days in zone 8b. The last frost comes by Mar 20 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 13.
Months with highs of 62–84° and lows of 40° or more: March, April, May, September, October and November. 2.4 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Experiment from natural hazards, river flooding is the largest share (50%); heat waves, cold waves, winter storms and ice storms together are 8%. Normals are averages; the hazards page covers the extremes.

Warmer than it used to be
The last 30 years in Experiment averaged 0.6° warmer than the 1900s. The biggest change is in December (+1.8°).
A smaller shift than in 97% 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 Experiment compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Experiment’s place among Georgia’s.
