Surfing originated in ancient Hawaii and has evolved from a central part of Polynesian culture to a modern sport. It involves riding ocean waves toward shore on a surfboard. There are three main types of surfing boards - longboards, shortboards, and stand-up paddle boards. Surfing was first documented by Europeans in 1769 and the modern sport can be traced to Hawaiian surfing traditions. It continues to grow in popularity around the world with major competitions, though it is not yet an Olympic sport.
