About Keta Reef - Oshima
Facing, offshore wind, exposure, level and swell range are estimated. Facts: verified, surf details estimated.
The spot faces W (259°), so it takes swell from the W. The wind blows offshore from the E (79°). It is sheltered to the open swell. It suits intermediate surfers and up. It works in 4–15 ft of swell. The sea floor shelves moderately: 10 m deep about 200 m out (1 in 21). On a typical 5 ft, 11 s swell the waves here would break hollow. The sea is about 18°C in February, its coldest month (2 mm shorty), and 27°C in August, its warmest (no wetsuit). No town nearby. No bookable town within 50 km: the nearest, Funabashi, is 121 km away. Nearest airport: OIM (OIM), 5 km.
Water about 25°C: no wetsuit. Typical sea temperature for the time of year, not a forecast.

Day scores here are the conditions out of 80; a trip's score on the results is the same conditions out of 100. The journey never scores. The forecast reaches about 10 days. Energy is the swell's power in kJ per metre of wave, from its height and interval: it grows with the square of each, so a long-period swell hits far harder than a short one the same size. The word under the swell is the wave's shape, our estimate from the sea floor. Wind is in knots: 10 kn is about 19 km/h. The arrow points where the wind blows to; offshore wind, blowing from the land out to sea, is green and says so.
