Houma, LA 70397 Frost Dates
Houma, LA: when does the frost end?
Around 02/05 is the usual last spring frost, about 161 days away. Fall's first freeze usually shows up around 12/17, roughly 312 days after the last spring frost.
Houma sits in USDA Zone 9b (25 to 30°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 16 weeks until Houma's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/05 isn't a guarantee
02/05 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/07 and only about 1 year in 10 sees frost after that.
Houma against the rest of the dataset
