Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Apr 21 |
| 50% (the "average" last frost) | May 4 |
| 10% (cautious: only 1 year in 10 freezes later) | May 20 |

| 10% (early: 1 year in 10 freezes this soon) | Sep 23 |
| 50% (the "average" first frost) | Oct 7 |
| 90% (late: most years have frozen by now) | Oct 21 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
