70125, near Westwego, LA: the frost window

Zone 9b

Typically, the last spring freeze lands around 01/24, roughly 149 days out. Fall's first freeze usually shows up around 01/02, roughly 341 days after the last spring frost.

Westwego sits in USDA Zone 9b (25 to 30°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

Westwego's growing season runs out in roughly 18 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 01/24 isn't a guarantee

01/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/23 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/28 and only about 1 year in 10 sees frost after that.
