Maresias

Maresias is São Sebastião's marquee break — a fast, powerful beach break on the São Paulo north coast that peaks into punchy, sometimes hollow a-frames over a sand bottom with rock at each end. It lights up on S/SE groundswells with N/NW offshores and is the competitive home beach of Brazil's pro scene, so the lineup is crowded and the standard is high. Best from autumn into winter (roughly April–September), with summer bringing smaller, more inconsistent pulses.
