Tundras have cold, windy climates with low levels of rainfall. Snow is nearly always on the ground, except during summer. The latitudinal range of the tundra is from 60 to 75 degrees north.
In the winter, there is very little light, and for parts of the short summer, the sun shines for almost 24 hours a day. During most seasons, vegetation grows in rock depressions where the wind is blocked and the temperatures are slightly higher. Averages temperatures in the winter are between -20 and -30 degrees Fahrenheit. In the summer, an abundance of wildflowers bloom, and average temperatures rise to just under 50 degrees Fahrenheit. The amount of precipitation in the tundra averages between 6 and 10 inches, which is comparable to some deserts.
