About Oshima - Sunanohama
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces SW (206°), so it takes swell from the SW. The wind blows offshore from the NE (26°). It is sheltered to the open swell. It suits intermediate surfers and up, because of a steep sea floor. It works in 3–13 ft of swell. The sea floor shelves very steeply: 10 m deep about 100 m out (1 in 10). On a typical 5 ft, 11 s swell the waves here would break hollow. The sea is about 18°C in February, its coldest month (2 mm shorty), and 27°C in August, its warmest (no wetsuit). The town to stay in is Ōshima, 6.3 km away (about 15 min by car).
Water about 23°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
