Perdido Beach, AL: when does the frost end?

Zone 9a

The last spring frost here typically falls around 02/28, about 184 days from today. Fall's first freeze usually shows up around 11/29, roughly 277 days after the last spring frost.

Zone 9a (20 to 25°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 Perdido Beach, not a forecast for this year.

Stretching the season past the first frost

With roughly 13 weeks until Perdido Beach's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 02/28 isn't a guarantee

02/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/20 and only about 1 year in 10 sees frost after that.

Perdido Beach against the rest of the dataset
