Surf Forecasting Help

Hey guys I am wondering if any of you can give me some help with surf forecasting fundamentals.
At the moment i'm just using sites like Magic Seaweed, Surf-forecast.com and local websites and cams - Surf.co.nz and Surf2Surf.co.nz (pretty avg in NZ as they only show the main breaks and not some of the off the beaten track spots).
I am wanting to try and learn more about using weather forecasts and what not to help me, and hopefully pick days when other reports from these sites may be wrong. I have just recently found this weather report website www.metconnect.co.nz (login - myweatherplus, password - weather4u) but I have absolutely no clue what to look for and if it is even worth looking at (cant find xxxxx on Dunedin) but anyways i guess what i'm asking is what type of charts/reports do i use and what do i look out for?
Cheers any help much apprieciated
