Frost dates for Washington, VA, ZIP 22746

Zone 7a

Around 04/16 is the usual last spring frost, about 231 days away. The first fall frost typically arrives around 10/27, about 192 frost-free days later.

The USDA Plant Hardiness Zone Map puts Washington in Zone 7a (0 to 5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

Zone 7a around Washington has about 9 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.

How much risk comes with planting early here

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.
