Port Vincent, LA 70769 Frost Dates
Port Vincent, LA: when does the frost end?
Typically, the last spring freeze lands around 02/09, roughly 165 days out. Fall's first freeze usually shows up around 12/13, roughly 308 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Port Vincent in Zone 9a (20 to 25°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 15 weeks until Port Vincent's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/09 isn't a guarantee
02/09 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/12 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/10 and only about 1 year in 10 sees frost after that.
