Maui is a tropical island with a mild year-round climate tempered by the Pacific Ocean. At sea level, the average afternoon winter high temperature is around 79°F (26°C) during the coldest months of December and January. August and September are the hottest summer months with average temperatures of about 86°F (30°C). Like most volcanic tropical islands, however, many different microclimates make it essential to pack for a variety of conditions: swimsuits and light hot-weather clothing for the beaches, a lightweight windbreaker for the occasional shower at higher elevations, and protection that is more serious during inclement conditions when hiking Haleakala.
