Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Dec 26 (prior Dec) |
| 50% (the "average" last frost) | Jan 22 |
| 10% (cautious: only 1 year in 10 freezes later) | Feb 27 |
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) | Dec 20 |
| 50% (the "average" first frost) | Jan 12 (next year) |
| 90% (late: most years have frozen by now) | Feb 12 (next year) |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Jan 31 | Jan 8 (next year) |
| 32°F (freeze) | Jan 22 | Jan 12 (next year) |
| 28°F (hard freeze) | n/a | n/a |
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 34949
Dates count from your average last spring frost (Jan 22) and first fall frost (Jan 12). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
