Mocambique Beach is the biggest beach on the island, stretching about 8.5 miles along the northeast coast. You can easily access the beach from the paved highway at various points, making it convenient to pull over and check the surf. The beach has a shifting sand bottom that can produce some hollow peaks when conditions are right, often reaching up to head high. With plenty of space, it’s usually not too crowded, which is great if you're looking for some waves to ride.

The surf here can handle swell sizes from about 2 feet (0.6 meters) to 8 feet (2.4 meters). It typically breaks left and right over sand, making it suitable for different wave riding styles. Your best chances for good waves are with northeast and east-northeast swells, and the ideal wind direction is from the southwest to west-southwest. Low to medium tides are preferred, and the waves can be good for beginners, intermediates, and even some experts. The middle stretch of the beach is generally the go-to spot, but keep an eye on the north end, known as Ponta das Aranhas or Praia Grande, especially when solid east swells are rolling in. There, you can find some nice lefts thanks to the small islets offshore.

Access to Mocambique is easy, and the beach tends to stay less crowded compared to other spots in Brazil, especially on school days. The vibe here is friendly, making it a chill place for surfers to hang out. While it's a fun spot for a variety of surfers, just be mindful of the conditions on bigger days, as there's no channel, and it can get tricky. Fall and winter bring the best surf, but you can find waves here year-round.
