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.

April: The Sweet Spot Emerges

April is where everything clicks. The average swell climbs to 2.0m, period pushes 12.7s, and ideal wind hits 43%—the best yet. SW swell dominates at 52%, with notable contributions from SSW (15.1%) and WSW (10.8%), meaning the bulk of the energy arrives from the optimal to passable western quadrants. Wind-wise, E and ENE winds combine for 20.5%, while SSE and S breezes back off. The onshore SSW wind drops to just 11.1%. Long-period groundswells wrap cleanly into Trigg Point, offering well-shaped peaks and hollow sections. Expect consistent 1.5-2m sets with occasional 2.5m waves. This is the start of the prime window, and conditions are often pristine for hours.
