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.

CAUTION
No Water at Hosmer Campground
As of September 30, 2025, water at Hosmer Campground in the Summit District is shutoff due to a waterline break. Water is available 24-hours at Headquarters Visitor Center one mile up the road. At this point we don't have an estimate for when repairs will be complete.
CAUTION
Expect Long Waits at the Summit Entrance Station Before Sunset
Due to a high volume of traffic, cars may be temporarily turned around at the gate when capacity is reached. Purchasing a pass online does not guarantee entry at sunset. To ensure timely access, arrive 3 hours before sunset.
