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) | Apr 8 | Apr 22 | May 8 | Oct 9 | Oct 22 | Nov 3 | 161 / 183 / 201 |
| 32°F (freeze) | Mar 25 | Apr 11 | Apr 29 | Oct 18 | Oct 30 | Nov 12 | 180 / 202 / 223 |
| 28°F (hard freeze) | Mar 7 | Mar 27 | Apr 12 | Oct 26 | Nov 9 | Nov 26 | 206 / 227 / 251 |
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.
