Tornadoes in California by the numbers
The archive contains 480 tornado records, 97 injuries, and 0 fatalities for California. These totals describe documented events rather than the probability at a particular address.
The longest path recorded in the state dataset is 26.4 miles on May 25, 2011. Path length can cross county or state lines and does not describe width or intensity.
When California tornadoes happen
March leads the historical monthly count with 85 records. June has the smallest count, at 13. Seasonal peaks reflect recurring weather patterns, but every year evolves differently.
Use the monthly chart as climatology, not a calendar guarantee. Tornadoes can occur whenever sufficient instability, moisture, lift, and wind shear overlap.
How residents should use the history
Know the safest room in every building you use, enable more than one warning source, and check the local forecast when severe weather is possible. During a warning, the current polygon matters more than the historical average.
Mobile homes and vehicles are especially vulnerable. Plans for those locations should identify sturdy shelter that can be reached before a warning.

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.
