Houston hail storm history
Harris County·NOAA NCEI Storm Events Database·~75-day publication lag
Houston and Harris County sit in a corridor where Gulf moisture, atmospheric instability, and upper-level wind shear converge to create favorable conditions for hail-producing thunderstorms. The National Weather Service and NOAA Storm Events Database document a consistent history of hail events in this region, ranging from small pellets to damaging stones capable of affecting roofs, vehicles, and property. Understanding this local hail climatology helps homeowners prepare for storm season and evaluate repair costs when damage occurs.
Check if your roof was damaged by recent hail
Houston's hail season peaks in April, May, and June, when warm Gulf air masses collide with cool upper-level systems to trigger organized supercell thunderstorms. Secondary activity occurs in March and October as transitional patterns occasionally favor hail development. The Gulf's moisture supply in this region allows hailstones to grow larger than in inland areas with the same atmospheric dynamics, meaning storms that produce hail here often generate stones large enough to cause functional damage to standard asphalt shingles and other building materials.
