Plan winter squash, fall tomatoes, and pumpkin harvests against the conservative fall frost date.
Frost Dates & Planting Timing
When is the first fall frost in my county?
First fall frost dates range from late August in the Northern Rockies to mid-December in the Deep South. Look up your county's frost-date page for the full probability distribution. The conservative bound (10% probability, 9 of 10 years not yet frosted) is your harvest deadline for sensitive crops.
