Jean Lafitte, LA 70183 Frost Dates

When can you plant in Jean Lafitte, LA?

Zone 9b

Typically, the last spring freeze lands around 02/10, roughly 166 days out. The first fall frost typically arrives around 12/12, about 306 frost-free days later.

Zone 9b (25 to 30°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 Jean Lafitte, not a forecast for this year.

What to do before the first frost

About 15 weeks of growing season left in Jean Lafitte before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 02/10 isn't a guarantee

02/10 is the middle of 30 years of NOAA records, not a promise. Plant by 01/09 and you're betting against frost in roughly 9 years out of 10. 03/10 is the safer bet, historically only a 1-in-10 chance of frost that late.
