This guide breaks down the weather month by month, helping you decide when to visit for your ideal Hawaiian getaway.

Overview of Honolulu’s Climate

Honolulu enjoys a tropical climate, characterized by relatively consistent temperatures year-round. There are two main seasons: the dry season (Kauwila) from April to October, and the wet season (Hooilo) from November to March. However, even during the wet season, rainfall is often brief and localized, rarely ruining an entire day. Trade winds provide a cooling breeze, making even warm days comfortable. Humidity is generally high throughout the year.
