Hamilton, VA 20129 Frost Dates
Hamilton, VA: when does the frost end?
The last spring frost here typically falls around 04/16, about 231 days from today. Fall's first freeze usually shows up around 10/25, roughly 189 days after the last spring frost.
Zone 7a (0 to 5°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Hamilton, not a forecast for this year.
Stretching the season past the first frost
With roughly 8 weeks until Hamilton's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/16 isn't a guarantee
04/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/07 and only about 1 year in 10 sees frost after that.
