Washington, VA 22749 Frost Dates
Washington, VA: when does the frost end?
Around 04/16 is the usual last spring frost, about 231 days away. Fall's first freeze usually shows up around 10/27, roughly 192 days after the last spring frost.
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.
Stretching the season past the first frost
With roughly 9 weeks until Washington's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/06 and only about 1 year in 10 sees frost after that.
