Winkipop - surf spot statistics

Best Surf Season (April - September)

The heart of the action at Winkipop unfolds from April through September. As the Southern Hemisphere transitions into autumn and winter, the Roaring Forties kick into gear, firing consistent, long-period SW groundswells directly into the Bells Beach embayment. With the average swell holding steady around 1.3m and periods stretching to 12-13 seconds, Winkipop delivers fun, rippable to pumping waves. Crucially, this period sees the highest frequency of offshore NW-NNW-W winds, often associated with slow-moving high-pressure systems over the Great Australian Bight. The wind blows offshore over 45-55% of the time, grooming the long, right-hand walls into perfection. It's prime time for Winkipop's famous long rides.

Fair Surf Season (October & March)

October and March serve as the transitional gateways. In March, the tail end of summer fades and autumn patterns begin, with ideal wind percentages around 32%. Swell sizes remain solid, and the period stays up around 12s, but the wind consistency falters. October sees a similar pattern as spring delivers strengthening NW winds (39% ideal), but also more frequent frontal passages that can shift winds onshore. You'll find plenty of clean, solid days but also more variability. When the synoptic setup aligns – a high sitting south of the Bight – Winkipop can fire just as well as in the peak winter months.

Low Surf Season (November - February)

From November through February, Winkipop experiences its summer doldrums. The primary swell window remains active with persistent SSW-SW groundswell, but the average wave height dips slightly to 1.2m, and periods shorten to 11-11.5s. More critically, the dominant wind regime switches to SE-SSE onshore breezes, driven by the southeasterly trade wind fetch and sea breezes. Ideal offshore wind percentages plummet to just 25-32%. While the Bells Bowl can still offer fun, groveling waves on the smaller days, the classic Winkipop walls are often blown out or undersized. Look for brief windows when a strong high moves north, backing winds to the NW for a few hours – those are the moments to pounce.

December: Summer Sizzle

December brings the lowest ideal wind of the year at 29%, coupled with an average swell height of 1.2m and period of 11.1s. Swell direction is dominated by SW (42.2%) and SSW (33.7%). The wind is predominantly from the ESE (7.4%), SE (12.2%), and SSE (12.4%) – all onshore or cross-onshore for Winkipop. The few offshore wind opportunities come from W (8.7%) and WNW (5.5%) directions, often early in the morning before the seabreeze kicks in. Wave heights are mostly in the 0.5-1.5m range, providing small to fun-sized waves. It's a month for groveling on the inside sections; the classic Winkipop wall will be rare. Keep an eye on those early NW wind windows for a chance at clean, small waves.
