About Barra do sai mirim
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces E (96°), so it takes swell from the E. The wind blows offshore from the W (276°). It is exposed to the open swell. It suits intermediate surfers and up. It works in 2–8 ft of swell. The sea floor shelves moderately: 10 m deep about 300 m out (1 in 30). On a typical 5 ft, 11 s swell the waves here would crumble. The sea is about 19°C in July, its coldest month (2 mm shorty), and 28°C in February, its warmest (no wetsuit). The town to stay in is Guaratuba. Within 5 km we also list 1 surf spot.
Water about 24°C: no wetsuit. Typical sea temperature for the time of year, not a forecast.
