Frost dates for Sandy Springs, Georgia
Georgia · first & last freeze, from NOAA 1991–2020 climate normals
In a typical year, the last spring freeze around Sandy Springs comes near March 25 and the first fall freeze near November 9. One year in ten, a freeze still arrives after April 12 in spring — and one year in ten, the first fall freeze has already landed by October 26. NCEI's own growing-season statistic (days between freezes, percentiled per year) puts the median at 228 days.
Freeze-date probabilities, three thresholds
| Threshold | Last spring — 9 in 10 years past by | Last spring — typical (median) | Last spring — 1 in 10 years later than | First fall — 1 in 10 years by | First fall — typical (median) | First fall — 9 in 10 years by |
|---|---|---|---|---|---|---|
| 36°F — near-freezing (frost can occur) | March 21 | April 7 | April 22 | October 17 | October 29 | November 12 |
| 32°F — freezing | March 5 | March 25 | April 12 | October 26 | November 9 | November 27 |
| 28°F — hard freeze | February 18 | March 12 | March 31 | November 4 | November 22 | December 14 |
Measured at Atlanta Peachtree Ap, GA (USW00053863), 5.5 mi from the city's census reference point, elev. 1,002 ft. NOAA/NCEI 1991–2020 normals. Read each date column as odds over the 30-year record — e.g. "9 in 10 years past by" means only one spring in ten saw a later freeze than that date.
Frost-free windows (computed)
| Window (32°F ends) | Opens | Closes | Length |
|---|---|---|---|
| Cautious (1-in-10 freeze risk at each end) | April 12 | October 26 | 197 days |
| Typical (median freeze dates) | March 25 | November 9 | 229 days |
| Gambler's (9-in-10 freeze risk at each end) | March 5 | November 27 | 267 days |
Pure arithmetic on the freeze-date percentiles above — the "cautious" window opens on the date only 1 year in 10 still sees a later spring freeze, and closes on the date by which only 1 year in 10 has already frozen.
