Pacific Beach/Crystal Pier almost always has something to ride but is rarely truly good. It tends to close out on any longer period swell that creates surf in the overhead range, especially as you move away from the more defined sand bars of the pier. However, on the occasion that a combo of swells from the northwest and southwest is greeted by easterly wind (generally in the fall) fun peaks can be found up and down the beach. The other time this zones comes closest to shining is during short period northwest swells that most frequently happen in the spring.
