Union, WV: when does the frost end?

Zone 7a

Around 04/30 is the usual last spring frost, about 245 days away. Fall's first freeze usually shows up around 10/12, roughly 165 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Union 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 6 weeks until Union'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

04/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/17 and only about 1 year in 10 sees frost after that.

Union against the rest of the dataset
