Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Jun 8 |
| 50% (the "average" last frost) | Jun 24 |
| 10% (cautious: only 1 year in 10 freezes later) | Jul 11 |
Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.
First fall frost odds
| Chance the first 32°F freeze has happened by this date | Date |
|---|---|
| 10% (early: 1 year in 10 freezes this soon) | Aug 8 |
| 50% (the "average" first frost) | Aug 28 |
| 90% (late: most years have frozen by now) | Sep 12 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | n/a | n/a |
| 32°F (freeze) | Jun 24 | Aug 28 |
| 28°F (hard freeze) | Jun 7 | Sep 12 |
n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
Vegetable planting calendar for 83012
Dates count from your average last spring frost (Jun 24) and first fall frost (Aug 28). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
