Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Apr 23 |
| 50% (the "average" last frost) | May 6 |
| 10% (cautious: only 1 year in 10 freezes later) | May 21 |

| 50% (the "average" first frost) | Oct 11 |
| 90% (late: most years have frozen by now) | Oct 26 |
