Michigan Tornadoes by Month
Monthly Michigan tornado counts from the SPC historical archive, with a chart, peak month, quietest month, and interpretation notes.
June has the most Michigan tornado records in the archive (250); the full chart shows how all 12 months compare. Counts are historical observations, not a prediction for the next year.
Read the monthly chart
Michigan’s distribution is built from 1,106 records spanning 1951–2024. June ranks first and January ranks last in raw count.
Because the period covers many decades, the chart smooths out unusually active and quiet years. It cannot show whether a particular upcoming month will follow the average.
Why monthly counts change
The position of the jet stream, moisture return, frontal boundaries, storm tracks, and local terrain all help shape seasonal opportunities for rotating thunderstorms. Those ingredients do not arrive on a fixed schedule.
Population growth, radar coverage, survey practices, and public reporting also affect the database, especially for brief and weak tornadoes.
Use climatology with current forecasts
Climatology answers when tornadoes have been more common. An outlook answers where severe storms may develop in the coming days, and a warning identifies an immediate threat.
Use each product for its intended timescale. If your location enters a warning polygon, shelter regardless of whether the date falls inside the traditional season.

Data source and limits
Counts on this page come from the NOAA Storm Prediction Center historical tornado archive for 1951–2024. 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.
