São Lourenco is located between Bertioga and Maresia, offering a 60km (40mi) stretch of surf along the SP055. This spot features small rivermouth formed sandbars that create deeper channels. It's generally a nice place for surfers looking for manageable waves, especially those who are improving their skills. The vibe here can get a bit crowded, particularly at the corners, but there are plenty of peaks to catch, especially when you put in the effort to paddle out when conditions get bigger.

The optimal swell direction for São Lourenco is Southeast, but you can also catch waves coming from the East and South. The spot can handle swell sizes around 2ft (0.6m), with both left and right wave directions. It’s mostly a beach break, which means the waves come in over sand, making it a bit more forgiving. For the best experience, you’ll want to hit it with a Northwest wind and aim for low to mid tide. It's a decent spot for intermediate surfers looking to refine their skills.

Keep in mind that currents can be strong, particularly with East swells. Make sure to pay attention to the conditions, especially in front of the large condo development nearby. Overall, São Lourenco provides a solid surf experience, but you should be prepared for the challenges that come with crowded peaks.
