Boyce, LA 71431 Frost Dates
Boyce, LA: when does the frost end?
Around 03/02 is the usual last spring frost, about 186 days away. Fall's first freeze usually shows up around 11/17, roughly 260 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Boyce 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 12 weeks until Boyce's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/02 isn't a guarantee
03/02 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/25 and only about 1 year in 10 sees frost after that.
