Summary
In the 1991–2020 record, the median last spring freeze (32°F) at Florence 8 NE is Mar 22 and the median first fall freeze is Nov 10, for a typical freeze-free season of 235 days. In about 1 year in 10 the last spring freeze comes after Apr 8, and in about 1 year in 10 the first fall freeze arrives by Oct 31.

Compared with the median of 103 South Carolina stations in this dataset, the median last freeze here is 4 days earlier than the state median (Mar 26), the median first freeze is 1 day later than the state median (Nov 9), and the growing season ranks #42 of 103 by length (longest = #1). The spread between the 90% and 10% spring dates is 39 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 18 | Apr 4 | Apr 18 | Oct 21 | Nov 1 | Nov 14 | 193 / 213 / 235 |
| 32°F (freeze) | Feb 28 | Mar 22 | Apr 8 | Oct 31 | Nov 10 | Dec 1 | 213 / 235 / 263 |
| 28°F (hard freeze) | Feb 10 | Mar 6 | Mar 29 | Nov 6 | Nov 24 | Dec 19 | 234 / 262 / 295 |
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.
