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 27 | Apr 11 | Apr 23 | Oct 16 | Oct 30 | Nov 11 | 183 / 200 / 218 |
| 32°F (freeze) | Mar 14 | Mar 31 | Apr 15 | Oct 25 | Nov 7 | Nov 23 | 201 / 221 / 245 |

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.
