About Tyoushi River Mouth
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces SE (138°), so it takes swell from the SE. The wind blows offshore from the NW (318°). It is sheltered to the open swell. It suits beginners and up. It works in 3–11 ft of swell. The sea floor shelves moderately: 10 m deep about 250 m out (1 in 24). 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). For beginners the best month is usually November, with about 1 good days in 7. From the weather of past years. The town to stay in is Owase, 5.1 km away (about 10 min by car).
Water about 22°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
