Thomson, GA frost dates
From NOAA weather station Thomson 1.5SE (USC00098677), elevation 542 ft. The station is named for Thomson, and its coordinates are 1.5 miles from the Census Bureau’s internal point for Thomson city.
Summary
In the 1991–2020 record, the median last spring freeze (32°F) at Thomson 1.5SE is Mar 14 and the median first fall freeze is Nov 17, for a typical freeze-free season of 252 days. In about 1 year in 10 the last spring freeze comes after Mar 31, and in about 1 year in 10 the first fall freeze arrives by Nov 3. The station averages 30 nights per year with a low of 32°F or colder.
Compared with the median of 126 Georgia stations in this dataset, the median last freeze here is 7 days earlier than the state median (Mar 21), the median first freeze is 5 days later than the state median (Nov 12), and the growing season ranks #39 of 126 by length (longest = #1). The spread between the 90% and 10% spring dates is 38 days, a measure of how variable spring is here.
Freeze probability table
| Threshold | Last spring occurrence | First fall occurrence | Season length (days) 90% / 50% / 10% | ||||
|---|---|---|---|---|---|---|---|
| Early (90% chance of a later freeze) | Median (50%) | Cautious (10% chance of a later freeze) | Early (10% chance by then) | Median (50%) | Late (90% chance by then) | ||
| 36°F (light frost possible) | Mar 9 | Mar 27 | Apr 12 | Oct 25 | Nov 6 | Nov 21 | 203 / 225 / 249 |
| 32°F (freeze) | Feb 21 | Mar 14 | Mar 31 | Nov 3 | Nov 17 | Dec 8 | 227 / 252 / 281 |
| 28°F (hard freeze) | Jan 31 | Feb 26 | Mar 19 | Nov 14 | Dec 4 | Jan 5 | 251 / 284 / 319 |
Read the spring “Cautious” column as the safer planting date: only about 1 year in 10 has a freeze after it. NOAA computes these from daily minimum temperatures at the station; your yard can differ, especially in low spots or at a different elevation.

Fall estimates count back from the median first fall freeze (32°F for tender crops, 28°F hard freeze for cool-season crops) by the longer days-to-harvest figure. These are rough planning aids, not recommendations for any specific variety; check seed packets and your county extension office.
