Windang Island • Surf Spot Statistics

The surf year at Windang Island is a battle between Pacific trade windswell and Southern Ocean groundswell. Because the beach is exposed to the east-southeast, it needs E/ESE/SE/SSE swell to light up. Clean conditions require W/WNW/NW/NNW offshore flow, and the seasonal migration of the South Pacific High dictates how often those two ingredients line up. From late autumn into winter, the westerly wind belts move north over NSW and the surf becomes distinctly more reliable; through summer, the trade winds and NE seabreezes keep the potential but make consistency harder to find.

Best Surf Season (April - August)

From April through August, Windang Island gets its most consistent combination of favourable swell direction and offshore wind. The percentage of ideal surfing winds climbs from 25% in March to 33% in April and then stays in the 35-38% range through August. Average swell periods peak at 9.4-9.7s, which is enough period to make the E/ESE/SE/SSE groundswell punchy and powerful. Southern Ocean lows and Tasman Sea cut-offs fire S/SE groundswell at the island, while the seasonal westerly belts supply frequent W/WNW/NW/NNW offshores. This is the most reliable window for clean, hollow surf.

Fair Surf Season (March, September - October)

March, September and October are the transition months. March still has summer water temperatures around 22.8°C, but the average period rises to 9.3s and the first true autumn offshores appear. September and October are the spring mirror: winter S/SE swell is still in the water, but NE/ENE blocks begin to return and the ideal wind percentage drops to 29-35%. These months can serve up excellent days, especially in the wake of a cold front, but they lack the consistency of the winter core.

Low Surf Season (November - February)

The summer months are the low season for consistent quality. From November to February, the South Pacific High builds again and pumps NE/NNE trade winds across the Tasman Sea. The average wave period drops to 8.3-8.8s and ideal surfing wind percentages fall to 19-23%. Swell heights remain rideable at around 5ft (1.5-1.6m), and the E/ESE/SE/SSE directions still show up, but onshore E/SE winds, strong afternoon sea breezes and shorter-period chop knock the quality down. Early mornings with a NW/NNW offshore can still produce fun waves, but surfers should not expect the reliability of autumn and winter.
