Houston hail storm history
Harris County·NOAA NCEI Storm Events Database·~75-day publication lag
Houston and Harris County experience hail events at a rate of 1.6 per year, with 16 documented hail events of 1 inch or larger recorded over the past 10 years. The city's position along the Gulf Coast creates atmospheric conditions favorable for hail development when spring storm systems move through the region. The largest hailstone on record in the Houston area measured 1.75 inches in diameter, reported during a 2025 event in the Champions Forest area of Fort Bend County.
Houston's hail season peaks during spring months—April, May, and June—when atmospheric instability and moisture from the Gulf of Mexico combine to fuel supercell thunderstorm development. Secondary hail activity occurs in March and October as transitional weather patterns bring organized storm systems through Harris County. The Gulf's persistent moisture supply contributes to rapid hailstone growth during favorable severe weather events, extending Houston's exposure period compared to inland Texas locations.
