When to go
You can catch amazing sunsets here year-round, so there really isn't a bad month to visit.
Because it is on the west coast and blocked by several mountains, sometimes the light in the morning can be a bit underwhelming. During sunset you can shoot from below the pier and catch the sun beaming in, or alternatively the view from on the pier is just as great.
Field tips
I would recommend a wide-angle lens (29mm) for this shot so you can incorporate as much of the pier and ocean as possible.
You can also use a telephoto lens to punch in on the waves for some very dramatic photos during sunset.
Be patient and wait for the right waves to enter your frame.

I feel like Pacifica is the gateway to the best the California coast has to offer, so just heading anywhere south you'll find other incredible views - Mori Point is one of my favorites close by. In the Pacifica area there are several great restaurants to eat at as well.
