  description: Huntington Beach is Surf City USA—the epicenter of American surf culture that has hosted the US Open of Surfing and shaped the sport's identity for generations. The pier and surrounding peaks produce remarkably consistent waves, catching both winter northwest swells and summer southern hemisphere energy. This accessibility means crowds that can make every session a contact sport, but also means there's always someone to surf with and an energy that defines California beach culture. The wide sandy beach, vibrant downtown, and year-round warmth create the quintessential SoCal surf experience.
