Temperate rainforests have two distinct seasons. One is long and wet, and the other is a short, dry and foggy summer. During the long wet season the temperature rarely drops below freezing (0°C and 32°F) and during the short, dry, foggy season the temperature rarely goes above 27°C and 80°F, this tells us why this biome is called a temperate rainforest. Even in the summer, when it is dry, the weather is cool, the fog supplies enough moisture to sustain the rainforest. The fog actually yields 18-30 cm (7-12 in) of precipitation each summer.
