For more than three decades, travelers have looked to one coastal scientist's annual rankings when planning their summer getaways. Dr. Stephen Leatherman, better known as "Dr. Beach," has spent his career studying America's shorelines, evaluating everything from beach erosion and water quality to public safety and coastal conservation.

Since 1991, Leatherman has released his annual ranking of America's Best Beaches. Each year, he evaluates roughly 650 public beaches across the country using a scientific scoring system based on 50 criteria, but only 10 make the list.
