Falfurrias, TX: when does the frost end?

Zone 9b

Around 02/25 is the usual last spring frost, about 181 days away. Fall's first freeze usually shows up around 12/01, roughly 285 days after the last spring frost.

The USDA Plant Hardiness Zone Map puts Falfurrias in Zone 9b (25 to 30°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 14 weeks until Falfurrias'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 01/19 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/18 and only about 1 year in 10 sees frost after that.

Falfurrias's growing season runs about 285 days, ranking 4,633 of 40,283 US ZIP codes measured here, longest to shortest. Within TX, it ranks 697 of 2,558.
