Lafayette, LA 70505 Frost Dates
Lafayette, LA: when does the frost end?
The last spring frost here typically falls around 02/13, about 169 days from today. Fall's first freeze usually shows up around 12/04, roughly 299 days after the last spring frost.
Lafayette sits in USDA Zone 9a (20 to 25°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 14 weeks until Lafayette's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/13 isn't a guarantee
02/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/13 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.
