Trigg Point • Surf Spot Statistics

Best Surf Season (March - May)

Trigg Point is a west-facing slab along Australia's Indian Ocean coastline, and it comes alive when the Southern Ocean storm track aims its energy at the southwestern corner of the continent. From March through May, the subtropical ridge starts to drift north, and the clash between lingering warm inland air and early autumn fronts produces regular, long-period SW to WSW groundswell. Average surf heights hover around 6-7ft (1.8-2.2m) with periods pushing into the 12-13s range, and the wind distribution shifts in your favour: the morning easterly offshore pattern becomes more reliable, with ideal conditions peaking at 48% in May. This is the sweet spot - plenty of size, clean lines, and the most consistent combination of swell and offshore wind on the calendar.

Fair Surf Season (June - September)

Winter is the biggest and most powerful time of year on the Perth coast. Average swell heights peak between 8-9ft (2.5-2.7m) and periods reach 13.1s, as deep Southern Ocean lows and frontal systems march through the Indian Ocean. The west-facing exposure of Trigg means SW, WSW and W swells hit hard and straight, producing heavy, well-defined waves. But the same storm track that generates these swells also brings frequent SW/W/WNW onshore winds. The percentage of ideal offshore flow drops from 43% in June to 32% in September, and you will spend more time watching the synoptic chart for clean windows between fronts. The water cools to 18-20°C and the rain increases, but when the wind swings offshore, winter delivers the most challenging and rewarding surf of the year.

Low Surf Season (October - February)

The Southern Ocean storm track retreats poleward during late spring and summer, and Trigg's average swell eases back to around 6-7ft (1.8-2.2m), with periods dropping from 13s to 11.6s. This is not flat by any measure, but the energy becomes less consistent and the daily sea-breeze cycle starts to dictate conditions. Offshore winds are still common in the mornings, especially from E and ESE, but the afternoon SW/S sea breeze often chops up the surface. November through February is the lowest consistency window, and the surf quality depends heavily on early starts and the timing of long-period groundswell that still sneaks up from the Southern Ocean. It is the dawn-patrol season: less size, warmer water, and plenty of fun walls for those willing to get out before the wind turns.
