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 19 | Apr 4 | Apr 19 | Oct 20 | Nov 1 | Nov 14 | 191 / 212 / 232 |
| 32°F (freeze) | Mar 3 | Mar 23 | Apr 6 | Oct 31 | Nov 11 | Dec 1 | 214 / 234 / 259 |
| 28°F (hard freeze) | Feb 15 | Mar 11 | Mar 30 | Nov 9 | Nov 26 | Dec 20 | 232 / 260 / 290 |
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.
