Georgetown, TX 78628 Frost Dates

When can you plant in Georgetown, TX?

Zone 9a

The last spring frost here typically falls around 03/06, about 190 days from today. The first fall frost typically arrives around 11/24, about 259 frost-free days later.

Zone 9a (20 to 25°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 Georgetown, not a forecast for this year.

What to do before the first frost

About 13 weeks of growing season left in Georgetown before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 03/06 isn't a guarantee

03/06 is the middle of 30 years of NOAA records, not a promise. Plant by 02/13 and you're betting against frost in roughly 9 years out of 10. 03/30 is the safer bet, historically only a 1-in-10 chance of frost that late.
