Heating and cooling a home in Atlanta
88% 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 Holdrege, NE.
Living with Atlanta’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
162 frost-free days in zone 6a. The last frost comes by May 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 Oct 11.
Months with highs of 62–84° and lows of 40° or more: May, June and September.

Warmer than it used to be
The last 30 years in Atlanta averaged 0.7° warmer than the 1900s. The biggest change is in January (+2.5°).
A smaller shift than in 94% 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 Atlanta compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Atlanta’s place among Nebraska’s.
