I’ve checked out quite a few books on surfing. There is probably no single book that has all the information you could want for a sport as complex as this, but Wingnut’s Complete Surfing is a standout as a guide for the beginner. It covers all the major topics from understanding waves, to understanding surf boards to basic maneuvers. It’s all you’ll need [plus some lessons] to started wave riding. There is enough detail here so that this book will retain your interest as you develop your skills. By the time you are done with it you will have received your $20 worth of value and you can pass it on to a new aspiring surfer to spread some positive karma.
The only two things I can be critical about this book are: 1) the pictures are B&W and not particularly beautiful [get your surf porn elsewhere] 2) no SUP surfing content [it’s like we don’t exist!].
