Flora and Fauna in Oahu
The eastern (Koolau) side of Oahu is much cooler and wetter than the western side of the island, which tends to be dry and arid. The island's official flower, the little orange ilima, grows predominantly in the east, but lei throughout the island incorporate ilima. Numerous tropical fish call the reef at Hanauma Bay home, migrating humpback whales can be spotted off the coast past Waikiki and Diamond Head from December through April, spinner dolphins pop in and out of the island's bays, and dozens of islets off Oahu's eastern coast provide refuge for endangered seabirds.
