Coming to California in August, Help me plan my trip!

hi all
I'm coming to south california in august for 1 month with my mum to see if we'd like to move there in a year after I finish school.
I'm looking for some general advice on cheap places to stay, surf spots that won't be too crowded and which areas are nice to move to.
We will be travelling from san diego all the way to San francisco, spending most of our time in the area between san diego and LA.
From what I've seen I like the sound of an area like Carlsbad to live in: A smaller town with fairly good surf and not too many crowds/pollution.
We're finding it hard to find motels too, most seem to be charging like $75 a night, surely there must be some cheaper ones? Can anyone advise me some good ones to try
Thanks alot and any feedback is very appreciated
