About Sakawa Rivermouth
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces SE (137°), so it takes swell from the SE. The wind blows offshore from the NW (317°). It is sheltered to the open swell. It suits beginners and up. It works in 2–9 ft of swell. The sea floor shelves steeply: 10 m deep about 150 m out (1 in 14). On a typical 5 ft, 11 s swell the waves here would break hollow. The sea is about 16°C in February, its coldest month (3/2 wetsuit), and 27°C in August, its warmest (no wetsuit). The town to stay in is Odawara, 2.2 km away (about 5 min by car).
Water about 22°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
The score is the conditions only: the journey, the price and the partners never change it (how we score, how we earn).
