Need Info On Surfing Please

Hi, my name is Stacie. I'm writing a novel and am in need of some surfing knowledge. Any help is greatly appreciated. The male characters are twenty-five and the female is twenty. They are all good surfers. I am mainly wanting to know what a surfer may ask another when they arrive at the beach to surf, such as about the waves or weather for surfers. Also, any lingo and explanations for younger surfers is appreciated! It takes place on the North Shore of Oahu. Thanks!!
