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 1 | Apr 16 | Apr 30 | Oct 11 | Oct 25 | Nov 7 | 171 / 191 / 212 |
| 32°F (freeze) | Mar 16 | Apr 4 | Apr 19 | Oct 23 | Nov 4 | Nov 23 | 194 / 214 / 241 |

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.
