Trigg Point - surf spot statistics

Best Surf Season (April - June)

As the austral autumn settles in, the Indian Ocean aligns perfectly for Trigg Point. April through June sees the most favorable blend of consistent, long-period groundswells and a marked increase in offshore wind frequency. The mean swell height sits around 2.0-2.5m, with average periods pushing 12.7-12.8s, delivering powerful, well-defined lines off the reef. At the same time, the percentage of ideal surfing wind (NE, ENE, E, ESE) climbs to 43-49%, as high-pressure systems park themselves over the continent, funneling clean, offshore breezes across the beach. This is the window when you can score flawless, rippable waves session after session.

Fair Surf Season (March & July - September)

March acts as a transitional month, where the swell is still solid (1.8m average) and long-period (12.4s), but the winds are slightly less consistent (35% ideal). Moving into winter, July through September brings the biggest surf of the year, averaging 2.6-2.7m with periods of 13.0-13.1s. These are powerful, long-range swells generated by Southern Ocean storms that wrap beautifully into the West-facing beach. However, the offshore wind window narrows to 33-42%, and frequent cold fronts introduce more SW to W winds that blow directly onshore. You'll need to pick your days carefully, but when a high-pressure ridge aligns, the rewards are epic.

Low Surf Season (October - February)

From late spring through summer, the Indian Ocean storm track weakens, and the prevailing winds turn unfavorable. October to February sees average swell heights drop to 1.8-2.2m with shorter periods (11.6-12.8s), and the dominant swell directions shift increasingly toward SSW and SW. Worse, the ideal wind percentage plummets to 24-30%, as the sea breeze cycle and synoptic patterns favor S to SSW winds—directly onshore at Trigg Point. This doesn't mean the surf is flat, but quality takes a hit. You'll often find bumpy, onshore conditions, though occasional easterly morning breezes can still offer short windows of clean, if smaller, waves.

October: Swell Drops, Onshore Dominates

October marks a clear shift toward smaller surf and less favorable wind. The average swell height falls to 2.2m, with period still decent at 12.8s, but ideal wind plummets to 30%. Swell direction is heavily SW (48.7%) and SSW (9.5%), with some WSW (12.2%). These are still good swell angles, but the wind is now onshore much of the time. The wind rose shows SSW (16.7%) and S (13%) as the most common directions, both producing bumpy, choppy conditions. Offshore winds from E and ESE only total 14.8%. The quality takes a hit: waves are often lumpy and require a groveler. Early morning sessions before the seabreeze kicks in can still be fun, with chest-high sets. But the magic of winter is clearly winding down.
