The Ventura Pier had to be shut down during high tide Sunday because waves of up to 10 feet crashed onto the pier.
A surfer at the beach was rescued after being trapped in the high surf.
Extra staff and patrols were active along the coast.
"This is a pretty big surf and it is that's something that's a challenge to us both in the rescue capacity but also just the number of people that it brings to the coastline," said Ventura County Fire Department Battalion Chief Fred Burris.
The storm system moving down from the northwest was expected to bring rain to the region Monday morning.
