Ranked by deaths, injuries, damage and size together.
- Tornadoes and Flash Flood in Florida, June 23 to 24, 2009A frontal boundary gradually settled across the area on the 23rd and 24th. The energy associated with the boundary combined with warm afternoon temperatures to produce scattered thunderstorms mainly along and ahead of the boundary.
- Heat in Florida, October 7, 2023Southerly winds across the area ahead of a cold front over North Florida caused temperatures to be above normal across SE Florida, with high temperatures in the lower 90s and heat index values around 100 degrees.
- Heat and Lightning Strike in Florida, September 11 to 12, 2010A very warm and moist airmass in place across the area allowed for heat indices to reach 100 to 105 degrees and an afternoon seabreeze to develop each day. Scattered thunderstorms developed each afternoon along the boundary and a girl was injured by lightning in one storm.
- Heat in Florida, June 1 to 30, 1998A deep high pressure ridge persisted across the Gulf of Mexico and Florida throughout most of the June and into early July. It resulted in several long stretches of record breaking high temperatures.
- Heat and Damaging Wind in Florida, July 19, 2023A heat advisory was in effect for heat index values of 108-112F. Sea breeze storms across north-central Florida produced localized wet downbursts.
- Heat in Florida, July 3, 1997A high temperature of 97 degrees was recorded at Orlando International Airport. This was only six degrees above normal, but the heat claimed one life. A 22 year old man was found unconscious a parking lot laying on the hot asphalt.

- Heat in Florida, September 2, 2010A 6 month old child was left in a car for approximately 2 hours as afternoon temperatures reached the lower 90s in the Tallahassee area. The child eventually succumbed to injuries believed to be related to prolonged heat exposure.
- Heat in Florida, July 11, 2022Temperatures across South Florida were in the lower 90s with relative humidity values over 50%. This led to high heat index values and contributed to the death of a child who was left in a car during the afternoon.
- Heat in Florida, July 6, 2023Hot and very moist southerly winds across South Florida led to heat index values in the 105 to 109 range across the area.
- Heat in Florida, July 25, 2017High pressure in place with abundant moisture led to high temperatures and dewpoints. This led to the heat index reaching 108-110 degrees. With these high heat indices many people were treated for heat related illness at Miami Beach.
- Heat in Florida, July 25, 2017Deep layer high pressure remained over central Florida with a low-level ridge axis positioned over Lake Okeechobee, and a mid-level ridge axis across central Florida.
- Heat in Florida, June 15, 2012Typically high heat and humidity levels lead to reports of heat exhaustion at a summer camp in Davie.
- Excessive Heat and Heat in Florida, July 28 to 31, 2010Above normal temperatures and high humidity combined to produce heat index values above 110 degrees across parts of the Florida panhandle at the end of the month. Heat index values even exceeded 115 degrees in a few locations on occasion.
