Periscopes - surf spot statistics

Best Surf Season (May - September)

The heart of the dry season brings consistent southeast trade winds that blow offshore across the west-facing reefs of Periscopes. Combined with a steady diet of powerful SSW to SW groundswells generated by relentless Southern Ocean storms, this is prime time. Expect average wave heights in the 1.5-1.8m range with long periods averaging 14-15 seconds, delivering clean, rippable walls. With offshore wind conditions exceeding 90% for most of these months, the window for perfect waves is wide open.

Fair Surf Season (April, October, November)

These transitional months see a shift in the wind patterns. April still offers excellent conditions thanks to strengthening easterly trades, while October and November experience a return of more variable winds as the monsoon transitions. Swell quality remains high with solid SSW energy, but the percentage of clean offshore wind drops to 50-80%. You'll need to pick your windows, but when it aligns, the waves can be just as good as the peak season.

Low Surf Season (December - March)

The wet season brings unfavorable westerly winds that blow onshore across Periscopes, drastically reducing the quality. While the swell direction remains favorable from SW, the average wave heights dip slightly to 1.3-1.4m and periods remain long, but the wind blows from the west and northwest over 50% of the time, creating choppy, messy conditions. Ideal offshore winds occur less than 15% of the time in January and February, making surfable waves a rare treat. Only a few windows of cleaner conditions may appear during cold fronts pushing through.

August: Consistent and Clean

August maintains the dry season momentum with a solid 90% offshore wind frequency. Swell heights average 1.7m, with a period of 14.5 seconds. The SSW direction dominates at 75% of the energy, and nearly 41% of that is in the 1.5-2m sweet spot. The wind shifts slightly to include more SSE component, but remains offshore and light to moderate in strength. The consistency is remarkable—day after day of clean, groomed swell. While the swell direction is slightly more southerly than June or July, the quality remains high, with plenty of rippable walls and the occasional bigger sets for those looking to push their limits.
