Diamond Head Cliffs

South Shore, Oahu, USA (HI)
🪸Sharp reef⚠️Shallow🦔Urchins🪨Rocks

Diamond Head Cliffs encompasses multiple breaks along the iconic crater—Lighthouse, Cliffs, Suicides, and Tongs. More easterly exposure than other south shore spots means it picks up more SE swell, but it's also the first spot to blow out when trade winds kick in.
