Brevard County, Florida
The state of Florida has so many shark attacks -- 244 from 2007 to 2017 alone — it warrants two spots on this list [source: ISAF]. Our first entry is Brevard County, where 144 attacks have occurred since 1882 [source: ISAF].
One reason Florida has a lot of shark attacks is that it has a lot of tourists eager to get into the water, and Brevard County is an easy hour-long drive for those already in the area to see Mickey at Disney World in Orlando. The county is home to the famed "Space Coast," 70 miles (113 kilometers) of coastline named for the space center at Cape Canaveral. In addition to the Canaveral National Seashore, visitors can also enjoy Cocoa Beach and Melbourne Beach.
While the number of shark attacks is nothing to sneeze at, Brevard County is dangerous for a few other reasons as well. In 2008, Forbes named Brevard County beaches the most dangerous places for rip current drowning. Between 1995 and 2017, 27 people drowned from rip currents in Brevard, a rate that's higher than any other county in the United States but Volusia in Florida (which we'll meet later) [source: Weather.gov]. Parts of this coastline also fall into Florida's "Lightning Alley," an area that has the most lightning in the United States. So when you're not worrying about sharks, worry about the forecast.
