Weather in The Hawaiian Islands is very consistent, with only minor changes in temperature throughout the year. There are really only two seasons in Hawaii, hoolio (winter) and kau (summer). Although the two seasons vary a bit in precipitation, the temperature variance is small. This is because there is only a slight variation in length of night and day from one part of Hawaii to another and because all its islands lie within a narrow latitude band. Also, we have a nearly constant flow of fresh ocean air across the islands, which regulates the temperature. The small seasonal changes provide the perfect habitat for wildlife to winter and rear their young.
- Hoolio (winter): November to April. Daytime highs at sea level range from 79–83 °F (26–28 °C)
- Kau (summer): May to October. Daytime highs at sea level range from 84–88 °F (29–31 °C)
