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.

August: Slightly Smaller, Wind Still Fickle

August maintains impressive swell size—average height 2.7m, period 13.3s. The swell direction shifts even more westerly: WSW (14.0%) and SW (25.6%) still dominate, but a higher percentage of waves are in the 2-2.5m range for SW (13.2%). Winds become even less cooperative: ideal offshore drops to 18%. The wind rose shows a strong westerly component: WNW (11.7%), W (11.2%), WSW (11.4%)—all onshore. The best chances for clean waves come during brief high-pressure interludes, often delivering cold but glassy mornings. Surfers need patience and a keen eye on the synoptic charts.
