As the weather gets warmer, swimmers and sunbathers will flock to some of the world's most beautiful beaches to cool off. Unfortunately, thousands of other beach-goers will have the same idea, making it difficult to enjoy the sun-drenched stretches of sand or the refreshing, turquoise waters.

Many of the beaches featured in the slideshow above are located in or near big and populous cities so it won't be surprising that these summer getaways will be congested during weekends or hot-weather days. And there are others, like Haad Rin beach in Koh Pha Ngan, Thailand, that are especially congested during specific times of the month—such as on world-famous, all-night parties.

But just because they are crowded during peak season doesn't mean these beaches are not worth a visit (they're popular for a reason). But if you don't like crowds, it might be wise to go earlier in the day or during the week.

1. Dalian, China

Located in northeast China's Liaoning province, Dalian's beaches are packed with crowds of thousands in the summer.

2. Dameisha Bathing Beach, Shenzhen, China

In the summer, China's numerous bathing beaches become major attractions. Dameisha Beach, a free-to-the-public beach located in Shenzhen, is the city's most popular, and draws thousands of sun-seekers each season. "Overcrowded would be an understatement," said Greg R., a TripAdvisor reviewer . "Bumper-to-bumper traffic with no parking, absolutely no space on the beach." Dameisha, however, could be a totally different experience off-season, or during the week. "Go mid-week to avoid the crowds," said William D., another TripAdvisor member. "It's like going to a different place."

3. Ipanema Beach, Rio de Janeiro, Brazil

Made world-famous by a bossa nova song, "The Girl from Ipanema," Ipanema Beach in Rio de Janeiro is perhaps, next to Copacabana, Brazil's most popular beach.

There are volleyball and soccer games, and windsurfing and wakeboarding in the water, while vendors stroll the stretch of sand to sell everything from beach towels and swimsuits to drinks and coconuts. If you want to relax, Ipanema Beach may not be for you, but if you're up for some people-watching, this beach will not bore.

5. Plage de Rabat, Morocco

7. Brighton Beach, England
