Forecast

Castaic has a warm, dry climate. Summers are usually sunny, hot, and very dry. Winters are cooler, with most of the yearly rain falling from November through March. Snow is rare, but nearby mountain peaks can sometimes get snow.

High air pressure often sits over the Pacific Ocean during summer. It helps keep skies clear and blocks most rain. In winter, low pressure systems can move in from the Pacific. These storms bring rain, clouds, and gusty winds. Santa Ana winds may also blow when high pressure builds over the Great Basin. These winds are warm, dry, and sometimes strong.

Castaic lies inland among hills and mountains, near the Santa Clarita Valley and Castaic Lake. The mountains reduce the cool ocean air that reaches the area, so Castaic can be warmer and drier than coastal parts of Southern California. The hills can also cause wind changes and make some areas cooler at night. Most days are mild to hot, with cool nights and only occasional freezing temperatures.
