Washington, VA 22740 Frost Dates

When can you plant in Washington, VA?

Zone 7a

The last spring frost here typically falls around 04/16, about 231 days from today. The first fall frost typically arrives around 10/27, about 192 frost-free days later.

Washington sits in USDA Zone 7a (0 to 5°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 9 weeks of growing season left in Washington before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/16 isn't a guarantee

04/16 is the middle of 30 years of NOAA records, not a promise. Plant by 04/01 and you're betting against frost in roughly 9 years out of 10. 05/06 is the safer bet, historically only a 1-in-10 chance of frost that late.
