The climate of Hawaii is typical for a tropical area, although temperatures and humidity tend to be a bit less extreme than other tropical locales due to the constant trade winds blowing from the east. Summer highs are usually in the upper 80s °F, (around 31°C) during the day and mid 70s, (around 24 °C) at night. Winter temperatures during the day are usually in the low to mid 80s, (around 28 °C) and (at low elevation) seldom dipping below the mid 60s (18 °C) at night. Snow, although not usually associated with tropics, falls at 4,205 meters (13,796 ft) on Mauna Loa on the Big Island in some winter months. Snow rarely falls on Maui's Haleakalā. Mount Waiʻaleʻale, on the island of Kauaʻi, is notable for rainfall, as it has the second highest average annual rainfall on Earth, about 460 inches (11.7 m). Most of Hawaii has only two seasons: summer from May to October, and winter from October to April.
