Waimea is built on the northern side of the Big Island. It lies on the slopes of the Kohala volcano in the saddle between this volcano and the famous MaunaKea (more information on Waimea). It lies on the boundary between the lush and rainy Hamakua coast and the dry and sunny north Kona resort coast. Because of these reasons the Waimea weather is difficult to predict.
Waimea is located 2676 feet (815 m) above sea level and this also influences the weather. Temperatures here are generally cooler compared to the rest of the island, and especially the many clear nights can feel crisp.
