Conditions at Trigg Point in March
March: The Autumn Engine Starts to Hum
March marks the beginning of Trigg's real surf season. The average swell height remains around 6ft (1.8m), but the period climbs to 12.4s as stronger Southern Ocean lows push groundswell into the southwestern Australian coast. The direction spectrum tightens around the prime SW-SSW window - SW holds at 50.3% and SSW at 27.7% - while WSW also starts to make its presence felt at 3.9%. More importantly, the wind balance shifts in your favour: ideal offshore flow from the NE through ESE now accounts for 34% of the time, and the morning E/ESE breeze is more reliable. Water temp is a still-warm 22.3°C and air temps average 22.4°C. This is the pivot month where you can score proper long-period swell with less of the summer seabreeze curse, setting the stage for the best months of the year.
