San Antonio hail storm history
Bexar County·NOAA NCEI Storm Events Database·~75-day publication lag
San Antonio and Bexar County experienced 40 hail events of 1 inch or larger over the past 10 years, with 18 of those classified as significant at 1.5 inches or greater. The city's location at the southern edge of the Texas hail corridor makes it vulnerable to spring thunderstorms, particularly when Gulf moisture moves northward and encounters frontal systems. The largest recorded hailstone in the area reached 3 inches in diameter, documented during a May 2025 event near Culebra Road and Talley Road in northwestern San Antonio.
Hail in San Antonio concentrates heavily between April and June, with secondary activity in March and July. The May 27, 2025 event that produced 3-inch hail near Government Canyon State Natural Area and tennis ball-sized hail in northwestern areas exemplifies the severe thunderstorm potential during these spring months. This seasonal concentration aligns with the interaction of warm Gulf air and spring frontal systems that regularly affect the region.
