Lefthanders - surf spot statistics

Best Surf Season (March - May)

Western Australia’s autumn emerges as the prime window for Lefthanders. During these months, the Southern Ocean fires up consistent SW to WSW groundswells with average heights hovering in the 1.9-2.3m range and periods stretching into the 12.5-12.9s zone. Ideal offshore winds from the ENE to ESE quadrant blow most reliably—around 22-29% of the time—creating clean, hollow walls. High-pressure systems stall over the Bight, funneling light land breezes in the mornings before sea breezes kick in. This is when the wave quality peaks: punchy, rippable, and often with that long-period push.

Fair Surf Season (June - August & September - November)

Winter brings the biggest swells of the year—average heights climb to 2.6-2.8m with periods often exceeding 13s. However, the wind regime turns hostile: low-pressure systems parade across the Southern Ocean, dragging strong W to NW onshore winds that ruin the surface. Only 18-22% of the time do we see offshore flow, usually during brief post-frontal clearing. Spring (Sep-Nov) sees a gradual transition: swells remain sizable (2.2-2.6m) with long periods, but wind consistency wavers as synoptic patterns shift. Still, when a high settles in, expect some stellar sessions.

Low Surf Season (December - February)

Summer delivers the smallest and least consistent surf of the year. Swell heights average just 1.8-1.9m with periods dropping below 12s. The dominant SSE to S winds blow side-onshore or onshore for the west-southwest facing beach, keeping ideal offshore windows below 17%. Incoming tropical moisture and sea breezes often add chop. Only the occasional rogue SW groundswell from a Southern Ocean storm can salvage the swell—but overall, this is the time to travel or explore other spots.

July: Peak Winter, Peak Size

July sees the largest average swell height of the year at 2.8m and the longest average period at 13.1s. Swell direction is heavily concentrated in the SW (18.8%) and WSW (15.7%) quadrants, with a considerable amount of waves exceeding 2.5m (1.0% SW, 1.5% WSW). This is pumping, heavy, and firing—but only for those who can handle the frequent onshore winds. Ideal offshore wind sits at just 21%. NW (9.3%), W (11.0%), and WSW (10.6%) winds are the rule, generated by intense low-pressure systems. The few offshore days (primarily from NE) produce epic, world-class barrels, but they are rare and often tied to cold fronts.
