During the winter, between November and February, world-famously huge waves in the order of 15 m (50 feet) high, break along Oahu's relatively untrammeled north shore. As a result, the coast attracts thousands of surfers and onlookers. Sunset Beach is one of the three prime surfing locations in the area. The others are Banzai Pipeline, off Ehukai Beach and Waimea.

The annual Triple Crown of Surfing is held in Sunset Beach and is one of the most lucrative events on the competitive surfing calendar. The big surf break known as Backyards, at the northern end of the beach, is also popular with windsurfers.

Sunset Beach is a low-key place and, especially during the summer, when the swells and rips die down there are few tourists. There are some decent swimming and snorkeling possibilities in the surrounding area. If you are on Oahu in the winter, it is better to visit Sunset Beach on a weekday.
