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 30 | Apr 12 | Apr 27 | Oct 14 | Oct 27 | Nov 8 | 178 / 197 / 215 |
| 32°F (freeze) | Mar 18 | Apr 1 | Apr 14 | Oct 23 | Nov 4 | Nov 19 | 197 / 217 / 239 |
| 28°F (hard freeze) | Mar 3 | Mar 22 | Apr 5 | Nov 1 | Nov 15 | Dec 2 | 219 / 242 / 266 |
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.
