Baton Rouge, LA 70815 Frost Dates
Baton Rouge, LA: when does the frost end?
The last spring frost here typically falls around 02/25, about 181 days from today. Fall's first freeze usually shows up around 11/26, roughly 276 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 Baton Rouge, not a forecast for this year.
Stretching the season past the first frost
With roughly 13 weeks until Baton Rouge's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/25 isn't a guarantee
02/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/29 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/19 and only about 1 year in 10 sees frost after that.
