Frost Dates in Georgia
First and last frost dates across Georgia, computed from 62 NOAA weather stations (1991–2020 climate normals). Your exact date depends on your city and microclimate — use the ZIP lookup on the main tool for a station-specific answer.

Frost dates by city
Median dates from the nearest NOAA station to each city. The "cautious" date is the 10% spring value — planting after it means only a ~10% chance of a later frost.
| City | Nearest station | Last spring frost | First fall frost | Growing season | Safe transplant |
|---|---|---|---|---|---|
| Atlanta | Atlanta Hartsfield-Jackson Int · 9 mi | Mar 15 (cautious: Apr 4) | Nov 20 | 252 days | Mar 29 |
| Savannah | Savannah Intl Ap · 7 mi | Mar 2 (cautious: Mar 25) | Nov 30 | 270 days | Mar 16 |
| Augusta | Augusta Bush Fld Ap · 7 mi | Mar 23 (cautious: Apr 9) | Nov 9 | 232 days | Apr 6 |
How frost varies across Georgia
Spring frost timing spans about 77 days across the state. Brunswick in southeastern Georgia typically sees its last spring frost around February 8, while Blairsville Exp Stn in northern Georgia doesn't clear frost until about April 26. Within any city, low spots and valleys run colder than the station average; areas near buildings and pavement run warmer.
When to plant in Georgia
As a rule of thumb, cool-season crops (lettuce, peas, spinach) can go in 2–4 weeks before your last spring frost; warm-season transplants (tomatoes, peppers) should wait about 2 weeks after it — around April 4 for the statewide median. Check your city's row above rather than the statewide median: a 77-day statewide spread makes the city-level date the one that matters.
These are climate normals (what's typical), not forecasts. For the current year, watch the 10-day forecast around your planting date.
How this is computed
Statewide medians are the median of the 62 NOAA stations' median frost dates — half the stations run earlier, half later. City rows use the nearest station with 30-year freeze records. Dates are 32°F freeze probabilities from NOAA NCEI 1991–2020 U.S. Climate Normals; nothing is estimated or interpolated.

Frequently asked questions
When is the last frost date in Georgia?
The statewide median last spring frost is March 21, but it ranges from February 8 to April 26 depending on where in the state you are. Use your city's row in the table above, or the ZIP lookup on the main tool, for a station-specific date.
When can I plant tomatoes outside in Georgia?
Warm-season transplants like tomatoes should wait about two weeks after your last spring frost — around April 4 for the statewide median. Your city may differ by weeks; check the "safe transplant" column in the city table.
How long is the growing season in Georgia?
The median growing season across 62 NOAA stations is 237 days, ranging from 176 to 314 days by location.
Why do frost dates vary so much within Georgia?
Frost timing follows latitude, elevation, and local terrain. Across Georgia, last spring frost dates span about 77 days — from around February 8 near Brunswick to April 26 near Blairsville Exp Stn. Microclimates (low spots, valleys, urban heat) shift dates further at the garden level.
Where does this data come from?
All frost dates are computed from the NOAA National Centers for Environmental Information 1991–2020 U.S. Climate Normals freeze data (public domain), using each station's 32°F freeze probability statistics. No dates are estimated or interpolated.
