The trick is in understanding how different areas handle different swell and wind directions.
In general though, you're looking for small waves, long periods, small seas and light winds. And, always keep an eye on the forecast for 12hrs beyond when you plan on being out. Sometimes swells or storms will arrive early.
If you can, find someone with experience to help you figure it out on the water.

INSAYN:
Is it possible for someone with experience (like...Spot, yakintup, PolePole, Zee, BSteaves, Pelagic Paddler, etc...) to do a How-To on how and what to read using various scenarios?
This is good info to learn and understand in real time, but with any How-To written for the interenet audience, it can be a starting point for newbies to start to get an understanding of what various data tells them (me).
squidgirl:
i agree with Insayn on the How to .....or maybe spot or someone can give some on hand lessons somewhere one weekend.
