Barra do Una (Peruíbe)

Barra do Una (Peruíbe) is a remote, exposed surf destination inside the Juréia-Itatins Ecological Station area, centered on beach-break waves that are heavily influenced by the Una River’s sandbars near the river mouth. The spot is known for clean groundswells and intermittent surf, meaning the best sessions are very dependent on getting the right swell angle and conditions. In winter, the swell and wind setup tends to come together more often. The ideal swell direction is southeast, and spot-level guidance highlights that the beach works best with offshore winds from the north-northeast (offshore). When the river-mouth sandbars are properly formed, peaks can produce longer, more rideable waves compared with the open beach. Safety-wise, conditions can be hazardous even in “small shore break” setups. Expect loose medium-to-large stones in parts of the beach, plus river-mouth currents and the possibility of rip currents. Sandbars may shift, and after heavy rains there can be occasional debris/logs near the river mouth. With no rescue/lifeguard coverage at the spot, it’s important to plan carefully and avoid going unprepared. Logistically, the area is very rustic: access involves a long dirt-road approach that can become difficult after heavy rainfall, and there is limited infrastructure once you’re there. For most visitors, bringing everything needed for the full session (and planning for weather/road limitations) is essential.
