Frequently asked questions

When is the last frost in Atlanta, TX?

The average last spring frost in Atlanta is around Mar 19, based on 1991–2020 climate normals. That's a median — about half of years see a later frost, so tender crops are safest going out a week or two after this date.

When is the first frost in Atlanta, TX?

The average first fall frost in Atlanta arrives around Nov 11. Crops still in the garden need to mature before then, and frost-tender plants need harvesting or protection as the date approaches.

How long is the growing season in Atlanta?

About 237 frost-free days on average, from Mar 19 to Nov 11. That comfortably fits long-season crops like melons and winter squash, plus spring and fall plantings of cool-season vegetables.

What USDA zone is Atlanta in?

USDA zone 8b on the 2023 Plant Hardiness Zone Map. Note that zones describe winter cold, not frost timing — these frost dates are the numbers to plan plantings around.
