Weather in Oahu

Weather in Oahu, as other Hawaiian Island is very consistent, with only minor changes in temperature throughout the year. This is due to the prominent influence of the prevailing northeasterly trade winds that lent Oahu its pleasant climate. With the constant flow of trade winds over the landmass, there are steady winds in summer months, which are the idle period for sailing as the warm seawater temperatures are an added benefit at that time of the year, especially in the Kenwood Cup. The moderating trade winds make even the warmest months bearable.
