Tornados

When is Florida's Tornado Season?

Florida has two Tornado Seasons.

The Summer Season, from June until September has the highest frequencies with usual intensities of F0 or F1 on the Fujita Scale. This includes those tornadoes that form from landfalling Tropical Cyclones.

The Deadly Spring Season, from February through April is characterized by more powerful tornadoes because of the presence of the jet stream. When the jet stream digs south into Florida and is accompanied by a strong cold front and a strong squall line of thunderstorms, the jet stream’s high level winds of 100 to 200 mph often strengthen a thunderstorm into what meteorologists call a supercell or mesocyclone. These powerful storms can move at speeds of 30 to 50 mph, produce dangerous downburst winds, large hail and the most deadly tornadoes.

What Time Are Florida's Tornadoes Likely to Strike?
Florida tornado climatology shows us that strong to violent tornadoes are just as likely to occur after midnight as they are in the afternoon. This unique feature makes these tornadoes more dangerous, because most people are asleep after midnight and cannot receive weather warnings relayed by commercial radio or television stations.


The solution to this is to have a NOAA Weather Radio in your home with a tone alert feature. This will allow you to receive warnings issued by your local National Weather Service office.
