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 18 | Apr 4 | Apr 20 | Oct 23 | Nov 3 | Nov 17 | 194 / 213 / 235 |
| 32°F (freeze) | Mar 2 | Mar 22 | Apr 8 | Nov 1 | Nov 13 | Dec 1 | 214 / 236 / 263 |

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.
