Rainfall in Maui � Showers are very common; yet while some of these are very heavy, the vast majority are light and brief � a sudden sprinkle of rain and it's over. Even the heaviest rain showers are seldom accompanied by thunder and lightning. Throughout the lowlands, in summer an overwhelming dominance of trade winds produces a drier season. At one extreme, the annual rainfall averages 17 inches (430 mm) to 20 inches (510 mm) or less in leeward coastal areas, such as the shoreline from Maalaea Bay to Kaupo, and near the summit of Haleakal�At the other extreme, the annual average rainfall exceeds 300 inches (7,600 mm) along the lower windward slopes of Haleakal�particularly along the H� Highway. If the islands of the State of Hawaii did not exist, the average annual rainfall on the same patch of water would be about 25 inches (640 mm). Instead, the actual average is about 70 inches (1,800 mm). Thus, the islands extract from the air that passes over them about 45 inches (1,100 mm) of rainfall that otherwise would not fall. The mountainous topography of Maui and the other islands is responsible for this added water bonus.
