With summer just around the corner, beach lovers are eager to find the best sandy spots in the U.S. The person with the answers: Dr. Stephen P. Leatherman, also known as Dr. Beach.

Every year, Leatherman ranks the top U.S. beaches along the Atlantic, Gulf, and Pacific coasts. He uses 50 criteria scored on a five-point scale, including sand softness, number of sunny days, cleanliness, and more.

A geoscientist and coastal ecologist, Leatherman earned his nickname while teaching a course on waves and beaches at the University of Maryland. His students began calling him “Dr. Beach.”

This year, Duke Kahanamoku Beach in Hawaii has been named the number one beach in the United States in Dr. Beach’s annual Best Beaches awards, published just in time for Memorial Day Weekend.

What Leatherman loves about Duke Kahanamoku Beach: “It has the finest white coral sand and clear water, with the iconic Diamondhead volcano in the distance,” he said in a statement. “Its location at the west end of Waikiki Beach means it’s far from the large crowds, making it the widest beach on this world-famous stretch of sand.”

The winning beach is protected by an offshore coral reef, which makes it an ideal spot for families with children. The nearby Duke Kahanamoku Lagoon is also a favorite for bathing and swimming. “Hawaii’s smoking ban on all beaches enhances public health and protects marine life, earning extra points in my ranking,” said Leatherman.

Unfortunately, North Carolina’s Lighthouse Beach, a long-time favorite, is absent from this year’s list due to severe erosion and environmental contamination from an old U.S. Navy submarine spy station revealed by coastal storms. “Lighthouse Beach is an erosion hotspot and currently caught in an environmental and bureaucratic mess,” said Leatherman.

From Hawaii to Florida, here are Dr. Beach’s 10 best beaches for 2024.

1. Duke Kahanamoku Beach – Oahu, Hawaii

Why it made the list: “Kahanamoku Beach is located on the west end of Waikiki Beach, far from the large crowds elsewhere,” says Leatherman. “It is the widest beach on this world-famous stretch of sand and protected by an offshore coral reef, making it a good beach for families with children.”

A tip: Check out the Duke Kahanamoku Lagoon, which is protected by an offshore coral reef—“ideal for families with children,” says Leatherman. The iconic Diamond Head volcano adds to its picturesque beauty.

2. Coopers Beach – Southampton, New York

Why it made the list: “Coopers Beach is located on the south shore of Long Island, shielded from the cold Labrador currents in the beautiful village of Southampton,” says Leatherman. “This first Gold Coast in the country is hundreds of yards wide, made of grainy white quartz sand, and backed by large sand dunes and extravagant mansions.”

A tip: “Some of the best beach access in the Hamptons exists on Coopers Beach; a snack bar serving lunch and drinks can be found here as well,” says Leatherman.

3. Wailea Beach – Maui, Hawaii

Why it made the list: “Wailea Beach is a series of five pocket beaches that are part of the Wailea resort complex, which provides public right-of-way for visitors,” says Leatherman. “The white coral sand beach gently slopes offshore and is great for snorkeling when the ocean is calm.”

A tip: “The beautifully landscaped park, adorned with tropical vegetation and flowering bushes and trees, makes this beach even more special,” says Leatherman.

4. Caladesi Island State Park – Dunedin/Clearwater, Florida

Why it made the list: “Caladesi is accessed via pedestrian ferry boat, private boats, or a long walk north from Clearwater Beach,” says Leatherman. “The white beach, composed of crystalline quartz sand, is soft and cushy at the water’s edge, inviting one to take a dip in the sparkling clear waters.”

A tip: “Leatherman recommends taking a kayak or canoe trip through the mangroves to see large blue herons and other birds that frequent this wonderful natural area.”

5. Beachwalker Park – Kiawah Island, South Carolina

Why it made the list: “Beachwalker Park is the public beach on the southern end of Kiawah Island, a nature-lovers coast where visitors can bring their canoes and kayaks to paddle through the tidal inlets,” says Leatherman.

A tip: “It’s fun to walk or bicycle down the fine-grained sand beach to Captain Sam’s Inlet to see thousands of birds,” says Leatherman. “The water isn’t clear, but it is clean and provides fantastic seafood.”

6. Main Beach – East Hampton, New York

Why it made the list: “Main Beach blends nature and built environment perfectly,” says Leatherman. “Wealthy summertime residents flock to the beaches protected by a conservation easement dating back over 300 years.”

A tip: “Main Beach is great for star-spotting as many actors and actresses visit for its peaceful, countryside setting,” says Leatherman. “The best way to get around is by bicycling to avoid parking issues.”

7. Poipu Beach – Kauai, Hawaii

Why it made the list: “Located on the sunny, dry side of this island, Poipu Beach is actually two beaches in one,” says Leatherman. “A tombolo, a narrow sand spit, separates the two pocket beaches, with the offshore island knocking down the big waves.”

A tip: “Small waves break gently on the shallow sandbar, creating a fun area for children to play,” says Leatherman. “As you move along the crescent-shaped beach, the waves vary in size.”

8. Delnor-Wiggins Pass State Park – Naples, Florida

Why it made the list: “This barrier island beach boasts beautiful white sand beaches and crystal-clear Gulf waters,” says Leatherman. “Activities include swimming, snorkeling, paddleboarding, shelling and fishing.”

A tip: “Pine trees provide welcome shade,” says Leatherman. “The park is still recovering from Hurricane Ian in 2022, so some areas remain closed.”

9. Coast Guard Beach – Cape Cod, Massachusetts

Why it made the list: “Accessible by bicycle from the Salt Pond Visitor’s Center or shuttle bus, Coast Guard Beach offers a spectacular view of the Nauset Spit barrier system and bay,” says Leatherman. “The picturesque old Coast Guard station still sits atop the glacial bluffs.”

A tip: “During the summer, beachgoers take quick, refreshing dips in the ocean as the water is chilly,” says Leatherman. “Always swim near a lifeguard and heed the red flags with shark images if present.”

10. Coronado Beach – San Diego, California

Why it made the list: “Coronado Beach is the toast of Southern California with its unique Mediterranean climate and fine sparkling sands containing mica,” says Leatherman. “The local landmark Hotel del Coronado has hosted kings, sheiks and celebrities for over a hundred years.”

A tip: “The beach is great for ship-watching and summer’s warm and mild surf,” says Leatherman. “Check online for water quality before swimming and surfing.”
