Two Mile/Easter Reef - surf spot statistics

Best Surf Season (May - August)

Winter roars to life along the New South Wales coast as a relentless conveyor belt of low-pressure systems spins up in the Southern Ocean. This is prime time for Two Mile/Easter Reef. The average swell height climbs to a solid 2.8-3.1m with long-period energy averaging 12.8-13.0s, delivering powerful SW to SSW groundswells that wrap beautifully into the south-facing beach. Simultaneously, the frequency of offshore winds from the N and NW quadrants peaks at 45-46% during May and June, cleaning up the face and creating hollow, rippable peaks. July and August squeeze out a few more XL days, though occasional strong westerly changes can add some chop. Still, this is the window for consistent, firing surf.

Fair Surf Season (March - April & September - October)

Shoulder seasons bring a mix of quality and variability. In March and April, the ocean still holds considerable winter momentum: average swell heights remain around 2.6-2.7m with 12.3-12.7s periods, and ideal wind conditions improve to 27-38%. The swell direction shifts slightly more WSW and W as the storm track wavers, but the south-facing break still picks up plenty of juice. September and October see a gradual transition toward spring; swell heights dip slightly to 2.8-3.1m in September (still solid), but offshore wind percentages drop to 38% and 32% respectively as northerly winds become more sporadic. Northern quadrant winds still deliver clean sessions, especially when strong high-pressure systems settle over the Tasman Sea.

Low Surf Season (November - February)

Summer is the quietest period for Two Mile/Easter Reef. The subtropical ridge shifts poleward, weakening the Southern Ocean storm machine and bringing smaller average swells of 2.4-2.5m with periods around 11.6-11.9s. These are mostly shorter-period S to SW windswells that lack the punch of winter groundswells. Onshore winds from the S, SE, and E dominate 30-40% of the time, blowing directly into the south-facing beach and ruining the shape. Offshore north to northwesterlies only blow 22-26% of the time, making quality sessions a rare treat. If a strong cold front sneaks through or a tropical depression drifts south, there can be fleeting moments of glory – but generally, it's a season of groveling in small, choppy conditions.

September: Spring Transition – Declining Swell, Still Good Windows

September marks the shift back to shoulder season. Swell averages 3.1m but the period stays high at 13.0s – the last gasp of winter groundswell energy. Direction remains west-heavy: WSW (13.3%) and SW (13.8%) share the load. Winds become more variable; offshore conditions drop to 38%, but N and NW winds still combine for about 17%. The number of all-day offshore days decreases; morning northerlies often turn into afternoon sea breezes. Still, early-season autumn patterns linger – one can get solid 2.5-3m waves with clean morning glass. The reef is still very much alive, and if you pick the right day, you’ll score pumping, hollow waves. This month is for those willing to chase the weather windows before the full spring pattern sets in.
