Beaumont, TX Frost Dates
Average frost dates, USDA hardiness zone, and growing season length for Beaumont, Texas.
Gardening in Beaumont
Southeast Texas where the Gulf Coast meets the Piney Woods. Beaumont's gardens inherit both traditions — Gulf subtropical conditions with East Texas forest cover and acidic soil.
Zone 9a with extreme humidity — Beaumont is one of the wettest cities in Texas, averaging 60+ inches of rain annually. Your 278-day growing season is generous but the moisture promotes every fungal disease in the Southeast playbook. The acidic sandy loam soil is well-suited to blueberries and azaleas.
Beaumont's Cajun-influenced food culture means backyard gardens grow the holy trinity (onions, celery, bell peppers) as a civic duty. The proximity to Louisiana shows up in both the cooking and the growing.
What This Means for Beaumont Gardeners
The average last spring frost in Beaumont is around February 20, and the average first fall frost arrives around November 25. That gives you approximately 278 frost-free days to work with.
278 days is a long, productive season that supports two full rounds of warm-season crops plus continuous cool-season production through your mild winter. Most frost-sensitive crops can be transplanted by February 20, giving them months to produce before fall. Your winter garden is the real advantage — growing fresh vegetables in December and January while northern gardeners browse seed catalogs.
These dates are based on NOAA 30-year Climate Normal data for the Beaumont area. Your actual frost dates could shift 2-3 weeks in either direction in any given year. Learn more about our data sources.
