San Antonio hail map & storm history
San Antonio owns one of the most infamous entries in U.S. hail history: the April 12, 2016 storm that dropped grapefruit-sized hail across the north side and caused roughly $1.4 billion in insured losses — the costliest hailstorm in Texas history at the time.
The city sits at the southern edge of the spring supercell corridor, and its biggest events tend to be exactly that shape: rare, massive, and concentrated — the kind of storm that defines a roofing company’s year.

The San Antonio hailstorm

Texas record hailstone at Hondo
A storm just west of San Antonio produced a hailstone measured at roughly 6.4 inches near Hondo — recognized as the Texas state record — underlining how violent the hail environment on the Edwards Plateau fringe can get.
Working the San Antonio hail market
San Antonio’s market runs on those landmark events: the 2016 storm re-roofed entire quadrants of the city, which means a large share of the housing stock now carries same-age shingles that will all take the next storm together.
Local crews that track swath history — not just the newest storm, but which neighborhoods’ roofs date to the last one — canvass with a story that opens doors: "your roof went on after the 2016 storm; here’s what Tuesday’s hail means for it."
Frequently asked questions
March through June, with April and May the peak months — both of San Antonio’s benchmark events (April 2016, and the April 2021 Hondo record stone nearby) fit that window. Fall events happen but are typically smaller.
