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 24 | Apr 9 | Apr 25 | Oct 16 | Oct 29 | Nov 11 | 182 / 201 / 222 |
| 32°F (freeze) | Mar 10 | Mar 28 | Apr 14 | Oct 26 | Nov 7 | Nov 24 | 203 / 224 / 248 |
| 28°F (hard freeze) | Feb 22 | Mar 15 | Apr 3 | Nov 3 | Nov 20 | Dec 11 | 226 / 251 / 278 |
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.
