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 29 | Apr 14 | May 1 | Oct 15 | Oct 27 | Nov 9 | 174 / 196 / 218 |
| 32°F (freeze) | Mar 11 | Mar 31 | Apr 18 | Oct 24 | Nov 5 | Nov 26 | 199 / 221 / 249 |
| 28°F (hard freeze) | Feb 22 | Mar 17 | Apr 6 | Nov 1 | Nov 18 | Dec 8 | 221 / 251 / 281 |
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.
