This overview was written April 23, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
Wilton, Connecticut has experienced 32 documented tornadoes within a 25-mile radius since 1950, according to the NOAA Storm Prediction Center. This relatively modest total reflects the region's position in the Northeast, where tornadoes occur less frequently than in the central United States but remain a periodic weather hazard. The distribution across decades shows notable variation, with the 1990s recording the highest activity at 8 events, followed by 7 tornadoes each in the 2000s and 2010s. The 1950s and 1980s each saw minimal activity with just 2 and 1 tornadoes respectively.
The intensity distribution of these tornadoes has remained generally modest. Of the 32 recorded events, 10 were rated EF0 on the Enhanced Fujita scale, representing the weakest category with winds below 85 mph. The majority—16 tornadoes—reached EF1 intensity with winds between 86 and 110 mph, capable of causing moderate damage to structures and vegetation. Only 6 tornadoes achieved EF2 status, with winds between 111 and 135 mph that can cause considerable damage to well-constructed buildings.
July stands out as the peak month for tornado activity in the area, accounting for 9 of the 32 recorded events. This summer maximum aligns with the season when atmospheric instability and moisture levels in the Northeast are most conducive to severe thunderstorm development. The costliest tornado on record occurred on July 10, 1989, when an F2-rated storm carved a half-mile path with a maximum width of 100 yards, causing $27.5 million in property damage. The area's only tornado-related fatality occurred during a much weaker F0 tornado on June 12, 1991, which caused $27,500 in damage along a 0.7-mile track.
Other notable events include the longest-tracked tornado, an F0 that traveled 12 miles on September 3, 1992, and the widest, an EF1 storm on May 15, 2018, that reached 400 yards across during its 3.7-mile path. The most recent tornado struck on August 13, 2023, a brief EF0 event that traveled 0.8 miles with a maximum width of 30 yards and caused no damage or injuries.
