A Bay / Big Island kitesurf, wingfoil and windsurf spot

United States · Hawaï

Spot currently openBeginner level 19.91 | -155.89

Overview

A Bay (Anaehoomalu Bay) is a kitesurfing spot located on the west coast of Big Island (Hawaii). This bay protected by a reef offers flat water conditions ideal for learning and progression. The northeast trade winds accelerate as they wrap around Mauna Kea, creating a Venturi effect that generates regular and sustained wind in the afternoon. The sandy bottom and shallow waters make it an excellent spot for beginners and intermediates.
