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 21 | May 8 | Oct 11 | Oct 23 | Nov 2 | 165 / 184 / 201 |
| 32°F (freeze) | Mar 25 | Apr 9 | Apr 23 | Oct 20 | Oct 31 | Nov 11 | 185 / 204 / 224 |

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.
