There's really not much available to fish for in saltwater at this time of year in half day range. A little bit of bottomfishing, but otherwise it's slim pickings.
If you have time (and money for it), consider a 3/4 day Coronado islands trip - they're catching decent yellowtail at the moment. A California yellowtail is a somewhat smaller cousin of the amberjack.
