Hail in Oklahoma, 2014 to June 2026: What Our Data Shows

Oklahoma occupies a distinct position in the hail data: smaller in total event count than Texas or Kansas, but with a trajectory that points upward. The state recorded 6,684 hail events across 77 counties from 2014 to June 2026. Its busiest full year is the most recent one, 2025, with 836 events, and each of the last three full years was higher than the one before it (742, 765, 836). That recency matters for contractors and homeowners assessing where storm risk is currently concentrated.

Year-by-Year Oklahoma Hail Events

* The 2026 row is a half year (January to June, the end of the NOAA file), so it is excluded from the peak-year ranking and from the average per year.

An Unusual Pattern: The Peak Is Recent

Kansas peaked in 2016, Texas and Arkansas in 2023. Oklahoma's pattern is different: its busiest full year is the latest one. The state had a relatively low 2014 entry point (279 events), a strong 2017 (653), then fell back sharply in 2018 (278) and again in 2021 (259, its lowest full year). What followed was a climb: 334 in 2022, 742 in 2023, 765 in 2024 and 836 in 2025. The maximum recorded hail size was 6.00 inches (2024), placing Oklahoma among the high-severity states in our dataset. The 2026 row (511 events through June) is a partial year and is not set against the full years.

Oklahoma County, home to Oklahoma City, appears in our national top-10 hail-heaviest counties list with 427 recorded events and a maximum of 4.00 inches. Cleveland County next door, home to Norman, is on the list too, with 365 events and a maximum of 3.41 inches. In dense urban areas that event frequency creates concentrated demand that rural storms cannot match on a per-household basis.

Oklahoma Contractor Licensing

Unlike Kansas or Texas, Oklahoma has clear statewide licensing requirements. Roofing contractors must be registered with the Oklahoma Construction Industries Board (CIB). The requirement is meaningful for homeowners: the CIB keeps a searchable public record and takes complaints if problems arise after a storm repair. Any contractor claiming to work in Oklahoma who cannot produce a CIB registration number should be treated with caution.

The Oklahoma counts can include hail records below 1.0 inch, because the source enters hail from 3/4 inch up. Details: how we build our storm and hail figures.

Hail counts in this post come from the full NOAA hail table: every county in 50 states and DC, 2014 to June 2026, loaded October 6, 2026. The two sets give different totals because they cover different counties. Dataset versions.
