Windang Island - surf spot statistics

Best Surf Season (May - September)

Austral autumn and winter deliver the most consistent and high-quality surf to Windang Island. As the South Pacific storm track intensifies, long-period groundswells from the SE to SSE quadrant become dominant, often generated by powerful mid-latitude lows south of Australia. The average wave period climbs to 9.5-9.7 seconds, providing punchy, rippable waves in the 1-2.5m range. Crucially, the percentage of ideal offshore winds (from the W to NW) peaks at 35-38%, ensuring clean, groomed faces. This is the window for the island's best waves: powerful, lined-up sets with minimal onshore contamination.

Fair Surf Season (March - April & October)

The transition months offer a mixed bag but can produce phenomenal sessions when conditions align. March and April see a lingering summer swell mix with early winter groundswells, while October bridges the gap back towards summer. The average swell height remains solid at 1.6-1.7m, but the period drops slightly to 8.7-9.4 seconds, meaning more chop and less power. Ideal wind frequencies range from 25-33%, so you'll need to pick your windows. When a westerly change coincides with a solid SSE swell, the result can be glassy, hollow waves peeling off the island.

Low Surf Season (November - February)

Summer brings a significant downturn in surf quality at Windang Island. The dominant swell shifts east and northeast, with shorter periods (8.3-8.8s) and a higher proportion of windswell. The average height stays around 1.5-1.6m, but the consistency of clean, offshore conditions plummets to just 19-23% of the time. Onshore seabreezes from the E to SE are the norm, creating bumpy, blown-out surf. While occasional groundswell pulses from a distant cyclone or Tasman low can light up the island, these events are rare. Expect small, grovelly conditions most days, best reserved for beginners or the easily amused.

February: Holding Pattern – Small but Punchy Potential

February mirrors January in many respects, with a slight uptick in average swell height (1.7m) and period (8.8s). The swell is still primarily from the eastern quadrant – ENE (15.5%), E (16.4%), and ESE (16.8%) – which provides rideable waves but often with onshore wind. The percentage of ideal wind improves marginally to 20%, as a few more passes from westerly fronts brush the coast. The wind rose shows a slight increase in NW and NNW breezes (especially at 10-20kph), offering brief windows of offshore grooming. When the stars align – a solid SSE groundswell coupled with a fresh northwest wind – the island can deliver fun, punchy waves in the 1-1.5m range. But be prepared to wait; consistency is low. The prevailing S to SSE winds (over 20% combined) mean most days are onshore and bumpy.
