The study ranked every one of 528 different beaches across the United States based on the total number of three potentially perilous phenomena: shark attacks, hurricane landfalls, and surf zone fatalities (taking into consideration dangers such as rip tides and sneaker waves). These factors were used to assign each beach an overall score out of 100—the higher the score, the higher potential risk to life.

Incredibly, the entire top 10 in the study is located in a single state: With just over one-tenth (1350 miles) of all of America’s coastline, Florida was found to be home to all 10 of the United States’ most dangerous beaches. Here they are in order, starting with the most dangerous.
