The coast also saw 5.7 inches of rain in a single day in February 2005, a reminder that winter atmospheric rivers don't skip this stretch of Ventura County.

If you're chasing the warmest weather, late summer through early fall is your window; if you're worried about rain, stick to April through October, when meaningful precipitation is rare.
