What Is the Climate in California's Mountain Region?
California has several mountain ranges, and their climates vary depending upon their location. For example, the Coastal Mountain range is located near the ocean and extends through two-thirds of the state. The coastal side is typically foggy, moist and cool, while on the eastern side, the temperatures are higher, and there is less precipitation.
California's large eastern Sierra Nevada range has a Mediterranean-like climate below 6,000 feet. Winters are wet and cool, while summers are warmer and drier. The highest regions have snow year-round, but most of it accumulates during the winter months. The climate of the state's southern mountain ranges is similar to that of the Sierra Nevada. However, the southern mountains are not as high, so they receive less snowfall.
