Lockport, LA 70030 Frost Dates

Lockport, LA: when does the frost end?

Zone 9b

Around 01/30 is the usual last spring frost, about 155 days away. Fall's first freeze usually shows up around 12/31, roughly 333 days after the last spring frost.

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 Lockport, not a forecast for this year.

Stretching the season past the first frost

With roughly 18 weeks until Lockport's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 01/30 isn't a guarantee

01/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/29 and only about 1 year in 10 sees frost after that.
