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 14 | Apr 29 | May 13 | Oct 6 | Oct 17 | Oct 29 | 151 / 171 / 191 |
| 32°F (freeze) | Mar 31 | Apr 15 | May 1 | Oct 14 | Oct 26 | Nov 9 | 173 / 193 / 215 |
| 28°F (hard freeze) | Mar 14 | Apr 2 | Apr 19 | Oct 24 | Nov 5 | Nov 24 | 196 / 217 / 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.
