The average precipitation, including melting snow, in the tundra is between 6 and 10 inches per year. Coupled with strong drying winds, the annual precipitation makes the tundra an area of extreme weather.
Spring and fall are only short periods between winter and summer. The tundra is the world's coldest and driest biomes. The average annual temperature is -18Â° F (-28Â° C). Nights can last for weeks when the sun barely rises during some months in the winter, and the temperature can drop to -94Â° F (-70Â° C).he tundra is basically like a desert when it comes to precipitation. Only about 6 - 10 inches of precipitation (mostly snow) fall each year. Below the soil is the tundra's permafrost, a permanently frozen layer of earth.
