Diamond Head Beach Webcam  -- a SurfLine webcam

This information is from the Outbound Collective website

Diamond head has a couple of good breaks close to town if you're looking to get away from the crowds at Waikiki Beach. There are easy trails down to the beach and channels to paddle out in - the paddle is a little long, so mentally prepare yourself. The two main breaks are Cliffs and Lighthouse. Cliffs is a more user-friendly wave with rights and lefts and Lighthouse is a higher-performance wave. These breaks pick up south swells and trade wind swells from the east, which means it can get really blown out by the afternoon. The breaks are fairly spread out so crowds usually aren't a factor unless there is a swell running or it's the weekend.
