Hawaii holds eleven of the thirteen climate zones that exist in the world, each with a unique ecosystem and climatic characteristics determined. Factors such as height, pressure variations, rain, wind and topography combine to create the most unique locations throughout the islands. Climates that can be found in the Hawaiian Islands include tropical wetlands, (from sea level to 137m (450 ft)), the arid and semi-arid (the warmer parts of the islands), the temperate (over 400 and 500m (1,300 to 1,500 ft)) and alpine areas (cold spots to 3,200 m (10,500 ft)). Make sure you are prepared for cold temperatures if you are climbing a mountain or volcano. Generally, the temperature drops 3.5 degrees Fahrenheit every 305m (1000 feet). Each of the Hawaiian Islands has four major climates: desert, rainforest, tundra and temperate zones, no matter which island you choose, you will have the opportunity to experience the wonderful natural diversity in any of them.
