When Is Tornado Season in Vermont?
Vermont tornado season by month, based on 49 SPC records from 1953 through 2023. See the peak and year-round safety context.
July is the leading month in Vermont’s historical record, but “tornado season” is a peak rather than a boundary. Tornadoes have been documented outside the busiest period.
The peak in Vermont
July accounts for 17 of the state’s 49 archived tornado records. The surrounding months may also be active, and a quiet peak month in one year does not change the long-term pattern.
Seasonality reflects the shifting overlap of warm, humid air, storm-producing lift, and winds that change speed or direction with height.
The quieter part of the calendar
January has the fewest records in this archive, with 0. A lower climatological count means lower frequency, not zero risk.
Cool-season tornadoes can be fast-moving and may occur after dark. Keep alerts enabled throughout the year rather than switching them on only in the peak month.
Prepare before the active months
Choose a shelter, test alerts, fit helmets, update medication and pet supplies, and practice a household drill before the climatological peak.
On any specific day, use the Storm Prediction Center outlook and local National Weather Service forecast. Historical season charts cannot identify today’s risk.

Data source and limits
Counts on this page come from the NOAA Storm Prediction Center historical tornado archive for 1953–2023. Older records are less complete, weaker tornado reporting increased with population and technology, and ratings changed from the Fujita scale to the Enhanced Fujita scale in 2007. A record is not a forecast.
