Oklahoma City hail storm history
Oklahoma County·NOAA NCEI Storm Events Database·~75-day publication lag
Oklahoma City, located in Oklahoma County, has experienced 9 documented hail events of 1 inch or larger over the past 10 years, with 3 of those events reaching the significant 1.5-inch threshold. The city sits in the heart of Tornado Alley, where the dryline, jet stream, and Gulf moisture converge to produce some of the most intense supercell thunderstorms in North America.
Hail season in Oklahoma City peaks from April through June, with May historically producing the most damaging large-hail events. The city's geographic position makes it vulnerable to rapid supercell development during spring months, when atmospheric conditions align to generate large hail capable of functional damage to standard roofing materials.

Oklahoma City's hail event count is based on NOAA Storm Events Database records, which rely on trained spotters, emergency management reports, and mobile phone observations submitted through mPING (Meteorological Phenomena Identification Network). The most recent documented event on November 20, 2025, produced 1.5-inch hail—the largest on record for Oklahoma County. Current-year data is excluded from the annual frequency table until October, when NOAA's Storm Events Database has processed the full hail season accounting for the standard 75-day reporting lag.
