About Flags - aliomanu reef
Facing, offshore wind, exposure, level and swell range are estimated.
The spot faces NE (66°), so it takes swell from the NE. The wind blows offshore from the SW (246°). 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 450 m out (1 in 44). On a typical 5 ft, 11 s swell the waves here would crumble. The sea is about 24°C in February, its coldest month (no wetsuit), and 27°C in August, its warmest (no wetsuit). For intermediate surfers the best month is usually March, with about 1 good days in 7. From the weather of past years. The town to stay in is Kapaa, 10 km away (about 20 min by car). Within 5 km we also list 2 surf spots.
Water about 26°C: no wetsuit. Typical sea temperature for the time of year, not a forecast.
