The neighborhood extends from the Ala Wai Canal (a channel dug to drain former wetlands) on the west and north, to Diamond Head on the east. Waikiki Beach is noted for its views of the Diamond Head tuff cone, its usually warm and cloud-free climate, and its surf break. Now, an abundance of both high-rises and resort hotels dot the Waikiki skyline. The beach is fairly short, with half of it marked off for surfers. For some distance into the ocean, the water is quite shallow, although there are numerous rocks on the bottom. As with most ocean beaches, the waves can have some force, particularly on windy days. The surf at Waikiki is renowned for its long rolling break, making it ideal for longboarding, tandem surfing, and beginners.
