Perris is by Temecula and can be good off the marina around that time. There are large crappie there and tons of bluegill in the 1-2 pound range are caught off the marina. In San Diego I know that El Capitan is doing well right now. I am sure that the slabs can be caught there in July also. Another fun place can be Irvine lake in Orange County. It is a pay lake but during that time you can night fish with floating lights.
