About Tornadoes in New London
This overview was written July 29, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.
New London occupies the point where the Thames River empties into Long Island Sound, on Connecticut's southeastern coast, and the tornadoes documented around the city have tended to strike in the heart of the warm season. An F0 tornado touched down in the area on September 8, 1958, and an F1 followed on July 19, 1963. Later midsummer events included an F1 on June 27, 1974, and an F0 on August 1, 1983. On July 1, 1998, tornadoes rated F1 and F0 struck the area on a single active day.
That midsummer pattern has carried into recent decades. An EF1 tornado touched down on July 31, 2009, and August 18, 2023, brought another EF1 to the vicinity. The area has also seen tornadoes well outside the usual season: on October 29, 2018, tornadoes rated EF1 and EF0 occurred, and an EF1 struck on November 13, 2021, deep into the fall.
For a coastal community in New London County, the takeaway from these events is straightforward: southern New England's tornadoes typically ride summer heat and humidity, but the late-October 2018 and November 2021 touchdowns show that the risk near the Sound does not end when summer does.
