Kauai Weather

Double Lines

Step off the plane and feel the warm embrace of Kauai with average yearly temperatures ranging between 84 and 69 degrees. Ocean temperatures are also perfect ranging from 71 to 81 degrees year round.

Kauai offers seven distinct microclimates, from lush interior spots to arid areas on the West Side. Mount Waialeale (elevation 5,148 ft) is at the heart of Kauai's uninhabited interior and is a quintessential rainforest with over 400-inches of rain per year. The rain that falls around Mt. Waialeale generally does not affect the coastal parts of the island, which get far less rain than the central spots (as little as 18-inches a year in western areas). Much of Kauai's rainfall is a nightly occurrence, and the rain showers that do occur are almost always brief. When you do see rain, wait for the beautiful rainbows that follow.

The trade winds in Kauai also keep things cool for visitors. The winds are generally light and help chase away much of Hawaii’s humidity. With such great weather, any time of year is a good time to visit Kauai.
