Longboarding bigger waves

Hi,
I just picked up a 9 foot epoxy longboard after taking some lessons, and at this point I am pretty comfortable riding the whitewash. I think it's about time to start surfing the bigger waves but I have a few questions... (I am surfing in Venice, CA by the way). So say I go out there in the lineup and decide to paddle for and catch a wave...how do you know where the water will break first, as in right or left? Basically, how do I know which way to make my first turn? And when should I start making that turn? or do I not need to turn at all? Any tips for transitioning from whitewash to bigger waves?
