Looking Ahead

Winds are forecast to gradually weaken and become light to moderate this weekend. Clouds and showers will favor our usual windward and mauka spots mainly in the morning and evening hours. An increase in trade wind showers is possible early next week, with potential for a few afternoon leeward showers as winds diminish.
