If you have any problems understand that stuff, or just making sense out of some aspects, go to a website titled www.stormsurf.com
, click on tutorials and read, it lays out in very simple terms everything, from the very beginning... from how highs & lows create wind, what fetch is, how wind swell changes to groundswell (definitions of each as well), what period is, what terms like significant wave hight mean, how water temperature affects weather, how to interpret virtual buoy readings, how to use several different sources to "paint a picture" and forecast rather than rely 100% on one source. And, for those really anal applied-maths lovin people how to calculate when a swell will arrive.
Actually, even after several years of having it firmly in my favourites I still go back there to refresh & jog my memory about some things. It is a wealth of serious & practical knowledge for any surfer.
After absorbing this knowledge you'll be able to sit on any headland near your local, watch the swells and see our beloved waves in a whole new and much better educated light. I did.
Read a chapter a night & make notes. Go to it!
