23873, near Alberta, VA: the frost window

Zone 7b

Typically, the last spring freeze lands around 03/31, roughly 215 days out. Fall's first freeze usually shows up around 11/06, roughly 221 days after the last spring frost.

Alberta sits in USDA Zone 7b (5 to 10°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.

Stretching the season past the first frost

Alberta's growing season runs out in roughly 10 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 03/31 isn't a guarantee

03/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/14 and only about 1 year in 10 sees frost after that.

Alberta against the rest of the dataset
