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 19 | Nov 1 | Nov 16 | 189 / 208 / 230 |
| 32°F (freeze) | Mar 1 | Mar 25 | Apr 11 | Oct 30 | Nov 11 | Dec 1 | 210 / 232 / 259 |
| 28°F (hard freeze) | Feb 14 | Mar 9 | Mar 29 | Nov 7 | Nov 24 | Dec 20 | 232 / 262 / 291 |
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.
