Grussaí (São João da Barra)

Grussaí in São João da Barra is a sandy, beach-break setup where surf is described as regular and fun, starting from small swells (below 1 m) and holding into larger surf (around 2 m+). Wave quality is generally considered good, and typical rides are often short to normal length (commonly in the 50–150 m range on better days), with both left and right breaking reported. For wind, providers describe trade-wind influence, and surfing-specific optimal wind directions are consistent: NW, West, and Southwest. In the wider São João da Barra (Grussaí / Atafona) region, conditions are also described as more dependable in the afternoon thanks to a thermal sea-breeze window, roughly 1:00 PM to 5:30 PM during the listed months. Winds are reported as regular, with gusts noted (up to around the mid-teens mph in one dataset). Crowd and comfort-wise, weekday sessions are commonly reported as empty, while weekend crowds are described as few. On busier days the beach can feel noisy (e.g., music and car noise), and the area can get crowded during Brazilian summer holidays in January and February. Safety considerations for this beach include potentially reduced visibility when the water is turbid/brownish from river sediment, plus hazards such as rip currents and fishing nets/debris near the river-mouth area. Lifeguard presence is reported as seasonal, while regional emergency response is available via local services (with emergency numbers provided in the safety baseline).
