About this spot

About

A Bay (also known as Willyama Bay) is a sheltered beach break on the Yorke Peninsula, associated with Willyama Bay and situated within/adjacent to a National Park coastline. The water is described as very clear and the break is generally consistent year-round, delivering fun-sized waves particularly when conditions align. For surfers, the break type is consistently reported as a beach break with peeling wave shape and medium peel speed. Ride lengths are typically short because the surf zone is beach-break driven, and performance is described as good to average depending on the swell and conditions. Optimal swell directions are given as south-southwest/southwest–south, with a working swell-height range reported around 0.5–1.5 meters by one description and up to about 1.0–2.0 meters in another. Wind conditions are best from the northwest (offshore/cleaning up the face). August is singled out as the best month, with a reported best-wind direction of northwest and monthly statistics indicating a higher likelihood of clean conditions than blown (clean 31%, blown 23% reported). Another description notes typical wind ranges around 10–20 knots and moderate reliability, with moderate gustiness. Safety is a key theme: sharks are explicitly listed as a hazard, and rip currents are noted as common depending on swell size. The area is remote and rescue is described as limited, so self-sufficiency matters. National Park rules apply (including entry fees and restrictions like no dogs and no drones without a permit), and visitors are advised to check for local shark sightings and bring adequate supplies before entering the water.
