The most recent quarter-size-or-larger hail storm recorded by NOAA within 25 miles of Brookings was on September 12, 2026. HailCheck refreshes from the NOAA Storm Events database daily, so newer events appear here as they are reported.
Brookings averages roughly 11 reported hail events per year within a 25-mile radius. Significant storms (quarter-size or larger) account for 46 of the 57 events recorded over the last five years.
The largest documented hail near Brookings in the last five years was egg-sized. Most Brookings-area hail falls in the marble-to-quarter range, with destructive storms (egg-size or larger) appearing roughly once every few years.
Most homeowners insurance policies in SD cover hail damage to roofs, siding, and gutters under the dwelling and other-structures coverage. Coverage typically requires the damage to be tied to a verifiable storm date — which is where the NOAA hail history above (and a HAAG-style test square validation) becomes important for the claim file.
Use the HailCheck address search to enter any street address in or near Brookings. HailCheck returns every NOAA hail event within a configurable radius, along with severity bands, dates, and storm narratives for Pro members.
If your property in or near Brookings took on hail during one of the storms above, the standard process for documenting damage is a 10×10 foot test square inspection. A HAAG-trained reviewer counts impact indicators — granule displacement, mat fractures, and bruising — within the marked square and produces a PASS or FAIL document for the claim file.
HailCheck offers a $99 photo-based HAAG-style test square validation. You submit photos from the field, our reviewer evaluates the impact indicators and cross-references the NOAA storm dates listed above, and a written PASS/FAIL determination is returned within one business day. We do not send anyone to the roof — the validation is built around the photos you submit.
Learn About $99 HAAG-Style ValidationBrookings sits inside the central United States hail belt, where warm Gulf moisture collides with cold continental air to produce supercell thunderstorms capable of dropping the hail documented above. Properties in this zone typically see at least one significant hail event every two to four years.
