Riviera de São Lourenço (Bertioga)

Riviera de São Lourenço (Bertioga) is a wide sandy beach spot known for clean water and easy access for both wind and wave sports. For kitesurfing, sources emphasize shallow, flat-to-small/medium wave conditions that work well for freeride, freestyle, and foil riding, with straightforward launching and landing space. Wind activity is most commonly associated with a thermal/sea-breeze pattern in the afternoons during warmer months. Several months in the late dry-to-spring stretch (July through December) are repeatedly highlighted for wind, with typical reported ranges around the low-to-mid teens up to the low 20s knots. One source also notes a specific afternoon window (about 13:00 to 18:00). Wind reliability is described as moderate overall, with stronger odds in spring. For surfing, it’s described as a consistent beach-break with waves breaking both left and right. The wave action typically starts below ~1m and can build to around 2m+ depending on swell, with good overall quality and normal rides commonly in the 50–150m range (with longer runs on better days). The most favorable swell directions reported are South to Southeast, and the wind effect is noted: Northwest/West winds can make surfing conditions cleaner. Safety-wise, the main cautions are crowds, swimmers, and rip currents, especially around busier periods. Mild localism is also reported. Riders are advised to avoid dense swimmer areas; during peak summer hours, kitesurfing may be restricted in designated swimmer zones. Using the northern end (near the Itaguaré river) is suggested for a quieter kitesurfing setup, while surfers often congregate toward the southern corner for more structured waves.
