The swell model on Friday is not favorable for either a newly minted OW diver or an evolution with a lot of new gear:

Some points:
Have you taken your gear into a pool and verified functionality, weighting, and leak checks? You will need to add about 5 lbs. to your total weighting in the ocean compared to the pool.
I assume your thermal is a 7 mm wetsuit, hood, and gloves. You can use your profile to list gear configurations. Read the dive reports and related threads in SoCal to get a feeling for what conditions have been like recently and what people are diving. Wrinkles events are excellent beach diving opportunities - one coming up at Lauguna.
Dive your gear the first time under very good conditions with a very experienced and attentive buddy. Avoid a long surface swim as that compounds problems like underweighting. Do some work and checks in the shallows (15-20 ft.) with minimal surf and swell.
