  description: Trigg Point is Perth's best-known surf break—a sand-dependent right-hand point that wraps around the rocky headland at Trigg Beach on the city's northern suburbs. When the sandbars align and a clean SW-W groundswell arrives, Trigg delivers long, workable walls with occasional barrel sections. The wave is heavily localized and extremely crowded, but the proximity to Perth's 2 million residents makes it the city's go-to spot. The surrounding beach and café scene make it a social hub for Perth's surf community.
