How it is computed
Hourly Open-Meteo Marine forecast (wave height, peak period and direction, swell) at a point just off Hanalei Bay, and the Open-Meteo wind at 10 m. Size: flat under 0.3 m, small under 0.8 m, fun under 1.5 m, good under 2.5 m (with a period of 8 s or more), big above. Wind: under 8 km/h light; otherwise offshore, cross-shore or onshore from its angle to the direction the beach faces. The best window is the 3 daylight hours with the best mix of size, period and wind. Rebuilt every 3 hours. Live map.
