Virginia's Peak Storm Months: Spring Start, Summer Surge
By StormAuditor Editorial Team · Published 2026-09-25 · Updated 2026-09-25
Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.
Damage-threshold ranges in this article are general guidance synthesized from industry and federal research — IBHS building-performance research, NWS severe criteria, and product standards such as UL 2218 (hail impact resistance) and ASTM D3161/D7158 (shingle wind ratings). Actual performance depends on product rating, age, installation quality, exposure, and impact characteristics — thresholds describe when damage becomes possible, not when it occurs.
Virginia's busiest storm day in the 12 months through September 24, 2026 came on March 16, with 622 events. The busiest stretch ran from June into early September, when eight of the ten busiest days fell.
On March 16, 2026, StormAuditor's public-record tally logged 622 Virginia storm events in one day, spanning flood, hail, tornado, and wind. It was the busiest single day in the 12 months through September 24, 2026. Virginia's peak storm months came later, though: eight of the ten busiest days in that window fell between June and early September 2026.
That split, one big early-spring outbreak followed by a long, dense summer, is the clearest pattern in the Virginia record. Here is what the data shows, month by month, and what it means for anyone lining up a storm date against a property.
The 12-month picture
In the 12 months through September 24, 2026, StormAuditor's public-record tally counts 8,802 storm events in Virginia, touching 129 of the state's 133 counties and independent cities. Wind accounts for 4,699 entries, hail for 3,268, flood for 774, and tornado for 87. The type counts are tallied separately and add up to slightly more than the headline total.
Warnings dominate. In the same window, 7,947 entries sit at the warning level, with 357 "reported," 330 from official backfill, and 194 "observed." A warning covers an area and a time window, so a property inside one was under the warning without necessarily seeing the storm's peak.
Month by month: when Virginia storms peak
March: one early outbreak
March 16, 2026 stands alone on the spring side of the calendar. At 622 events, it tops every summer day in the window. NCEI's Storm Events Database, in records available through June 2026, lists 90 Virginia entries for March 2026.
April and May: a slower build
NCEI lists 29 entries for April 2026 and 71 for May 2026. Only one spring day besides March 16 reached StormAuditor's top ten for the 12 months through September 24, 2026: May 27, 2026, with 245 events.
June through early September: the core of the season
This is where the volume sits. The busiest summer days in the 12 months through September 24, 2026 were:
- August 10, 2026: 566 events
- June 12, 2026: 417
- July 4, 2026: 411
- September 4, 2026: 389
- June 22, 2026: 368
- July 18, 2026: 363
- July 28, 2026: 356
- August 14, 2026: 266
NCEI records available through June 2026 point the same way, with 252 Virginia entries for June 2026, the highest month in that series. NCEI has not yet released July onward, so those months are missing from its data rather than quiet.
Winter: strong wind days
No winter day made the top ten by event count, but December brought strong wind. On December 29, 2025, NOAA's gridded analysis estimated gusts to 76 mph, a measured gust report near Linden reached 69 mph, and the highest measured station gust was 55 mph. On December 19, 2025, the analysis estimated 72 mph and a measured report reached 64 mph.
Hail and wind peaks by season
Virginia's largest hail arrived in mid-summer. On August 14, 2026, radar (NOAA MRMS MESH) estimated hail to 3.15 inches statewide, and 13 ground hail reports came in. The largest was 3.5 inches at Union Mills, from a storm chaser; reports of 2.75 inches near Lake Monticello and 2.5 inches near Charlottesville followed that same day. That 3.5-inch report was the largest ground hail report in the 12 months through September 24, 2026.
Other summer hail days paired radar with ground reports:
- July 26, 2026: radar 2.52 inches, 9 ground reports, largest 2.5 inches at Bumpass
- July 4, 2026: radar 2.28 inches, 14 ground reports, largest 1.5 inches
- June 23, 2026: radar 2.31 inches, 5 ground reports, largest 1.75 inches
- July 28, 2026: radar 1.93 inches, 7 ground reports, largest 2.5 inches near Mustoe
That last day is a useful reminder that ground reports can run above the radar estimate, not only below it. September 26, 2025 carries a 3.21-inch value, a radar estimate with no ground reports that day.
Wind peaks followed the same summer pattern. The strongest measured gust report in the window was 81 mph near Wise on August 11, 2026, from a member of the public. A ship near Raleigh Terrace reported 78 mph on June 14, 2026, and Richmond International measured 71 mph on July 18, 2026. On that July day, NOAA's gridded analysis estimated 77 mph, its highest Virginia value in the 12 months through September 24, 2026. All of those measured values top the NWS severe-gust criterion of 58 mph.
Where the counts cluster
Chesterfield County led Virginia in the 12 months through September 24, 2026 with 160 events in StormAuditor's tally. Fauquier and Loudoun followed at 159 each, then Hanover at 140 and Culpeper at 130. NCEI's county ranking, from records available through June 2026, orders things differently: Bedford 23, Loudoun 15, and Prince William and Fauquier at 14 each.
Where StormAuditor fits
StormAuditor's Virginia storm data page collects the statewide view. For a single property, Address Lookup shows NWS warnings, storm reports, and NOAA station observations for the address, free with an account. The Free Report Snapshot answers yes or no: did estimated wind reach StormAuditor's 45 mph screening level, or estimated hail its 0.75-inch screening level, at the address in the window checked. Those screening levels sit below the NWS severe criteria of 58 mph and 1.00 inch.
For seasonal planning, the Storm Calendar lays storm dates out over time (a Pro feature). When a date needs detail, the Weather Report lists every qualifying storm date with estimated peak gust and estimated maximum hail size from SAWE-2 and SAHE-2, the nearest measured evidence with distances, and NWS warnings.
Limitations
- Counts reflect the public record, and most Virginia entries are NWS warnings covering areas and time windows. A county total is not a count of storms that reached homes.
- MRMS MESH can underestimate wet hail and overestimate in very high reflectivity cores, so radar and ground sizes differ in both directions.
- Stations are spaced apart; peak gusts between them can exceed reported values.
- NCEI data lags by months and covers only records available through June 2026 here.
- Everything StormAuditor publishes is an estimate, not an on-site measurement, a damage determination, or evidence of cause. See the limitations page.
