Bullying by locals doesn't really happen and if you've experienced it, it's most likely a safety issue or you're violating some surfing etiquette. Head over to Reddit: https://www.reddit.com/r/surfing/wiki/index for their detailed beginner's guide.

I never had problems at San Onofre, but it's been a few years since I spent any time there (used to drive down the coast for meetings and would stop in).

This site seems to have some decent notes: http://www.thesurfingsite.com/Surf-Spots-Southern-California...

One thought - if you are a beginner or just starting out, don't paddle in with where the crowds are if you can help it. Find a spot a bit away that has waves suitable for the type of surfing you are trying (long board, short board). A long board will let you catch smaller (even junkier) waves easier.

I've surfed a lot of the spots around SoCal and never had a problem with any kind of aggression. There are plenty of guides to surfing etiquette out on the 'net and if you read them and take the lessons to heart, the odds of you having a real problem with anyone (at least here in SoCal) are slim to none. Basically, don't be a kook - be respectful and friendly, and you'll find the surfing community out here is a lot more welcoming than you might think.

Also, learn surfing etiquette first. Sit on the beach and really watch what is going on. Waves are typically surfed a single person at a time, so there is an entire unsaid process going on out in the water. Experienced surfers can never meet, yet get along in the water without ever speaking. While some of the process is a bit of peacocking it is mainly being in the best spot for the wave.

Rule 1, don't get in the way.

Military installations, if you can get on one. Trestles being the best example. Although that is not a beginner spot.

Go with a friend who knows the ropes. They'll take you to the right spot.

I started at Sunset, just up from Santa Monica. With an experienced buddy. Good times.

Almost anywhere in San Diego.

Manhattan beach is pretty low-key.
