About Koudono
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces SE (151°), so it takes swell from the SE. The wind blows offshore from the NW (331°). 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 gently: 10 m deep about 750 m out (1 in 73). 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 29°C in August, its warmest (no wetsuit). For intermediate surfers the best months are usually September and October, with about 2 good days in 7; in January and December, about 0. From the weather of past years. The town to stay in is Tosa, 7.8 km away (about 15 min by car). Within 5 km we also list 1 surf spot.
Water about 23°C: 2 mm shorty. Typical sea temperature for the time of year, not a forecast.
