I, the WeatherTiger, am a Floridaman.
This must be distinctly understood, or nothing can come of the hurricane history I am going to relate.
While I have never dialed 911 because a Taco Bell line was moving too slowly or been attacked by a trunkful of thawed iguanas, I am a third-generation Floridian with a record of zany antics, such as trying out for the US national team handball program despite having zero experience with or understanding of team handball.
I also forecast hurricanes for a living. It doesn’t get much more Florida than that.
July’s report: The science behind the hurricane season short | WeatherTiger
Storm tracker: Keep up with all active storms
All clear in the Atlantic for the next ten days means we can analyze threats on the horizon
Like all Floridamen, I know that Florida contains the multitudes. This is true of the wild variance in the meaning of “barbeque” between the northwestern and southeastern corners of Florida.
It is also true of hurricane season, with unique fingerprints of tropical risks between various parts of the state.
With no tropical activity in the Atlantic and none on the horizon for the next 10 days, let’s take a regional look at Florida hurricane climatology. While the hurricane season is one-third complete on the calendar, unfortunately it is only around 10% done in terms of Florida landfall activity, and much less than that for some.
In this column, I’ll examine when Central Florida, Southwest Florida, Southeast Florida, and the Panhandle experience peak hurricane risks, and when those threats arise.
Methodological note: I define the Panhandle as west of Lake City, Central Florida as east of Lake City and north of the Bradenton-Vero Beach line, and Southeast and Southwest Florida as south of that line and east and west of Lake Okeechobee, respectively. As storms have no respect for lines on a map, counts reflect that one hurricane may impact multiple regions.
The Panhandle: An early draw for storms with a 25% chance of late bloomers
Depending on the source, the National Magnet Lab in Tallahassee either attracts hurricanes, keeps them away, or emits 5G signals heralding a third non-consecutive term for Grover Cleveland.
While the truth remains out there, it is a fact that the Panhandle gets off to the fastest start of any part of the state, as “Steinhatchee Season” delivers a pipeline of mostly weak but wet tropical storms to the Big Bend in June.
Early hurricane landfalls, like 2005’s Category 3 Dennis, are possible in the first third of the season as well, mostly originating in the Caribbean; 9 of the 53 Panhandle hurricane strikes since 1851 have occurred prior to August (17%).
The August and September peak months of hurricane season see 58% of historical hits, split between direct landfalls out of the Gulf and Caribbean, like Hermine, and storms that continued into North Florida after initially striking Florida’s East Coast, like 1995’s Erin.

The final 13 historical hits (25%) come in October and November — mostly, like Michael, in the first half of October, with a steep drop-off in Panhandle landfall rates thereafter as the action shifts south.
Central Florida: Hurricane season starts later here with August, September to fear
Central Florida’s hurricane history reflects the broader identity crisis of the region, haphazardly mixing the tropical flavor of South Florida’s climatology with the “Boiled K-jun P-nuts” oeuvre of the northern Gulf Coast. Hurricane season gets off to a slower start here, with three historic landfalls in June and July.
Central Florida’s risks are the most sharply focused of any region on the peak season, with 25 of 40 (62%) of historical strikes occurring in August and September. Most of these storms are Southeast Florida landfalls that continued northwest into Central Florida, like 2004’s Frances and Jeanne, while a comparatively few are landfalls on the northeast Florida coast like 1964’s Dora.
The final 30% of activity occurs after September, divided between Southwest Florida landfalls moving inland, and direct hits like 1921’s Category 3 Tampa Bay hurricane, a storm that keeps hurricane climatologists awake at night as a very dangerous scenario if repeated.
Southwest Florida: Two times to cross your fingers
The final redoubt of the Florida panther, the Bubble Room, and the skunkape, North America’s southernmost native Sasquatch, Southwest Florida has a seasonal distribution of hurricane risks all its own.
June and July are quiet, with only one landfall since 1851, and August and September bring around half of all hurricane strikes.
The majority of those storms make initial landfall in Southeast Florida and continue west, with a handful like 2004’s Charley looping north out of the Caribbean.
After a late September lull, mid-October brings the highest frequency of direct landfalls to Southwest Florida, with 19 cases representing almost half of all historical hurricane strikes. Category 3 Wilma in 2005 is a classic example of this archetype, developing in the western Caribbean before launching northeast across South Florida.
Southeast Florida and the Keys: Two months have drawn the most devastating storms
Will Smith describes the climate of Southeast Florida as “five-hundred degrees in the Caribbean seas” where “the rainstorms ain’t nothin’ to mess with,” later adding “haha, na na na, woo!”
While Mr. Smith’s assessment of average summer high temperature misses the mark by around 407°F (193 Kelvin), he is correct that Southeast Florida has a different Köppen climate zone classification than the rest of the state — tropical monsoon, rather than humid subtropical.
This distinction influences Southeast Florida’s substantial hurricane risk profile, with direct landfalls usually originating from tropical waves out of the eastern Atlantic’s Main Development Region. June and July, before the African wave train cranks up, have only two hurricane landfalls to their account.
Twenty-six landfalls, including devastating hurricanes in 1926, 1928, 1935, 1945, plus 1992’s Andrew and 2017’s Irma, slot into the August and September peak months of the season and account for most historical direct landfalls.
Another 20 hurricanes, about 40% of the total, occur after September, and are a mix of Southwest Florida landfalls racing northeast and Caribbean-originating direct hits on the Keys.
The moral of this story? We’re just getting started, folks
In summary, history shows that Florida’s hurricane season has barely begun, and for some it will not peak for another two and a half months.
