Some beaches are just better than others.

And if you’re looking to celebrate Memorial Day weekend at one, the Associated Press recently uncovered which U.S. beaches are top-tier, according to coastal scientist Stephen Leatherman.

The Florida International University professor has ranked beaches in the last 30 years and he just updated his annual "top 10" list for 2021, which was published on his website Dr. Beach.

Leatherman ranks beaches with a rigorous criteria that includes 50 physical factors, such as sand softness, water temperature and number of sunny days. Each of these factors receive a numeric score on a five-point scale, and the beaches with the highest scores overall end up being added to Leatherman's top 10 list.

If you're planning to travel to a beach that's been hand-selected by a meticulous expert this holiday weekend, here are the ones that are going to make your beach trip count.

The U.S. beach that landed the top spot on Leatherman's list is Hāpuna Beach State Park, a recreation area that is located in Waimea. a county on the Big Island of Hawaii. It is more than 200 feet wide and is considered the biggest on the island.

"This white coral sand beach resides in a landscape dominated by black lava flows," Leatherman wrote in a statement to Fox News. "During the summer months, Hāpuna is a perfect place to swim, snorkel or scuba dive in the crystal clear and clean waters, but big waves during the winter can generate powerful rip currents. Fortunately, there are well-trained lifeguards at this state park."

While the U.S. Centers for Disease Control and Prevention is urging unvaccinated people to avoid non-essential travel during the pandemic, the health agency is not against beach visits.

Instead, the CDC is advising Americans who have yet to receive their COVID-19 vaccines to make cautious considerations before they visit a public beach. Safety protocols the agency recommends include wearing face masks, sanitizing hands regularly and making an effort to social distance while avoiding large gatherings.

For people who are fully vaccinated though, the CDC says these groups can go outside without a mask or physical distancing in most settings two weeks after their last dose. Some exceptions may apply depending on local mandates.

According to an updated Memorial Day travel forecast from the AAA, more than 37 million Americans will hit the road for the holiday weekend – and a good portion of these travelers are going to stop at beach destinations.
