About Oshima
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces N (342°), so it takes swell from the N. The wind blows offshore from the S (162°). It is exposed to the open swell. It suits intermediate surfers and up. It works in 2–9 ft of swell. The sea floor shelves very gently: 10 m deep about 1.4 km out (1 in 145). On a typical 5 ft, 11 s swell the waves here would spill softly. The sea is about 11°C in March, its coldest month (4/3 or 5/4, boots and gloves), and 27°C in August, its warmest (no wetsuit). For intermediate surfers the best months are usually February, April, November and December, with about 1 good days in 7. From the weather of past years. The town to stay in is Mikuni, 4.8 km away (about 10 min by car). Within 5 km we also list 1 surf spot.
Water about 19°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
