Urania, LA 71480 Frost Dates
Urania, LA: when does the frost end?
Around 03/19 is the usual last spring frost, about 203 days away. Fall's first freeze usually shows up around 11/12, roughly 238 days after the last spring frost.
Zone 8b (15 to 20°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 Urania, not a forecast for this year.
Stretching the season past the first frost
With roughly 11 weeks until Urania's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/19 isn't a guarantee
03/19 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/25 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/09 and only about 1 year in 10 sees frost after that.
