About Onjuku
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces S (159°), so it takes swell from the S. The wind blows offshore from the N (339°). It is exposed to the open swell. It suits intermediate surfers and up. It works in 3–12 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 17°C in February, its coldest month (3/2 wetsuit), and 27°C in August, its warmest (no wetsuit). The town to stay in is Shinmachi, 0 km away (about 5 min by car). Within 5 km we also list 1 surf spot.
Water about 22°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
