The climate of the chaparral varies greatly during the year. During the summer, the chaparral is very dry and desert-like and temperatures can reach over 100° F (38° C). Conversely, during the winter, temperatures can drop below freezing and hard frosts hit the land.
Most of the precipitation in the chaparral arrives during the late fall and early spring seasons. November through January brings some rain, but the raining season peaks in February. Precipitation slows after February and completely stops in May. During the summer an area of high atmospheric pressure forms and stops rain clouds from the Pacific Ocean from reaching the chaparral. Droughts result and plants and animals must adapt to the dry, hot weather.
