Santa Monica Mountains National Recreation Area - Climate

The Santa Monica Mountains have a true Mediterranean climate with hot, dry summers (80 to 100 degrees Fahrenheit) and relatively cool, wet winters (40 to 70 degrees Fahrenheit). Nights can be cool any time of the year. In the summer, the coastal side of the mountains is generally 10 to 15 degrees cooler than the inland side. In the winter this pattern is reversed with warmer temperatures along the coast.

Layer your clothing to be comfortable anywhere in the mountains. For safety and comfort, use a hat, sunscreen and appropriate shoes or boots.
