Hawaii Weather by Month
Hawaii, located in the central Pacific Ocean, is known for its tropical climate, stunning landscapes, and year-round warm weather. The state’s climate is primarily influenced by its latitude near the equator, the surrounding ocean, and the trade winds that blow from the northeast. Hawaii experiences two main seasons: the dry season (kau) from May to October and the wet season (hooilo) from November to April. Temperatures are relatively consistent throughout the year, typically ranging from the mid-70s°F to mid-80s°F (24°C to 30°C) along the coast, with cooler temperatures at higher elevations. The islands receive varying amounts of rainfall depending on location, with windward sides (facing the trade winds) generally wetter and leeward sides drier. The diverse geography of Hawaii, including volcanic mountains, lush rainforests, and pristine beaches, offers a wide range of outdoor activities, making it a popular destination for visitors all year long. Whether you’re hiking through lush valleys, relaxing on sandy beaches, or exploring volcanic craters, Hawaii’s climate provides the perfect backdrop for your adventures.
