Kaisers

South Shore, Oahu, USA (HI)
🪸Sharp reef⚠️Shallow👥Crowded👊Localism

Kaisers is the premier South Shore performance wave—a bowly, hollow right that empties into a deep channel with a left going over shallow reef. The fierce pecking order among locals makes this one of the more intimidating lineups in Honolulu.
