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 29 | Apr 12 | Apr 30 | Oct 15 | Oct 28 | Nov 9 | 175 / 199 / 221 |
| 32°F (freeze) | Mar 12 | Mar 30 | Apr 14 | Oct 24 | Nov 6 | Nov 25 | 201 / 222 / 248 |
| 28°F (hard freeze) | Feb 23 | Mar 18 | Apr 4 | Nov 2 | Nov 18 | Dec 10 | 221 / 248 / 278 |
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.
