HIWEATHER INFO
On any given day, the temperatures in the park can range from a high of 80°F (27°C) in Kīpahulu to a low of 30°F (-1°C) at the summit. In either area clouds and rain can quickly replace warm sunshine. Weather in the high-elevation summit and wilderness areas of the park is highly unpredictable and changes often. Cool temperatures, intense solar radiation, and rapidly moving clouds are characteristic. On average, the temperature drops about 3°F for every 1,000 foot rise in elevation.
