Hawaii Island Weather
Weather on all of the Hawaiian Islands is consistent, offering only minor changes in temperature throughout the year. There are really only two seasons: the summer months that extend from May to October and the winter months that run from November to April. The average daytime summer temperature at sea level is 85 degrees F. (29.4 C), while the average daytime winter temperature is 78 degrees (25.6 C). Temperatures at night are approximately 10 degrees F. lower. However, at higher elevations, temperatures can drop dramatically.
Hawaii Island is an incredible collection of many diverse micro-environments, each with its own weather. You can travel through all but two of the world’s different climate zones on Hawaii ranging from Wet Tropical to Polar Tundra, a result of the shielding effect and elevations of the massive volcanoes Maunakea and Maunaloa. Experience this for yourself as you explore Hawaii Island by car or helicopter. See the tropical rainforests in the Hamakua Coast, the cool uplands of Waimea, the volcanic deserts of Kau and the sunny beaches of Kona, all within the span of a day’s drive.
