About Kaifu Rivermouth
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces SE (113°), so it takes swell from the SE. The wind blows offshore from the NW (293°). 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 moderately: 10 m deep about 350 m out (1 in 33). On a typical 5 ft, 11 s swell the waves here would crumble. The sea is about 17°C in February, its coldest month (3/2 wetsuit), and 28°C in August, its warmest (no wetsuit). The town to stay in is Tomoura, 0.6 km away (about 5 min by car).
Water about 23°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
