Hi, welcome to San Diego!
If you haven’t found it already, you should attend the next Open Oscillator on August 14th at The Whistle Stop in South Park. You’ll meet a wide cross section of the local electronic scene there. Play a live set, too: one of our mottoes is “we can put up with anything for eight minutes.” 
There is also the Synth Meetup Group organized by Jesse Karras, Haector Benitez’s Resonancia Sound Lab (a Tijuana-based electronic music school that also hosts some events on both sides of the border), Sam Lopez’s Stay Strange noise shows, Haydeé Jimenez’s Borderland Noisefest series, the local edition of Modular On The Spot, and more. UCSD has a strong experimental music program, too, and some of the staff/faculty (Trevor Henthorn, sometimes Tom Erbe, etc.) are involved in various other events in the wider community.
