Hawaii doesn’t really have distinct seasons. There is winter, which is warm, and summer, which is warmer. Temperatures are hottest from July through September when daytime highs will be at or near 90°F. Even in “winter” the daytime temperature is usually in the 80s.
The coldest months are February and March with nighttime lows near 60°F. Temperatures drop with altitude, and there is frost above 4,000 feet in the winter. The top of the volcanos often have snow in the winter months. However, a short drive will take you back to the beach where you can swim and sunbathe. The average humidity ranges between 56-72 percent.
Rain in Hawaii
It rains somewhere in Hawaii almost every day of the year. Kauai and the Big Island’s northern areas get more annual rainfall than the rest of Hawaii. The surprise of island weather is that yearly rainfall may be more than 100 inches in one place and less than 20 inches just a few miles away.

Eastern: Windward Side
Tradewinds hit the east side of the islands first causing clouds to accumulate along mountain peaks and drop precipitation. This is the windward side of each island and it is wetter and a little cooler. If you prefer it cool with a little rain or showers, try the windward areas: Hana on Maui, Princeville on Kauai, or Hilo on the Big Island.
Western: Leeward Side
The western side of all islands is the leeward side and they are warmer and drier. Most of the popular tourist resorts are on the warmer and dry leeward side of the islands: Honolulu on Oahu; Wailea, Kehei and Kaanapali on Maui; Kona and the Kohala coast on the Big Island; and Poipu on Kauai.
