Houston, MS: when does the frost end?

Zone 8a

Around 03/28 is the usual last spring frost, about 212 days away. Fall's first freeze usually shows up around 11/01, roughly 220 days after the last spring frost.

Houston sits in USDA Zone 8a (10 to 15°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 9 weeks until Houston's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

How much risk comes with planting early here

03/28 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/15 and only about 1 year in 10 sees frost after that.

Houston against the rest of the dataset
