Conditions at Virac Harbour in August
August: Strongest Onshore Flow of the Year
August is the southwest monsoon at maximum strength, and it wrecks Virac Harbour. Average swell is still just 0.5m (1.5-2ft), period 7.2s, but the standout statistic is wind: SW 34.4%, WSW 15.3%, and SSW 12.3% combine for over 60% of all observations from the onshore south-west quadrant. That means relentless cross-onshore chop and hardly any clean faces.
Swell direction is a little more mixed--E 23.3%, ENE 16.8%, S 11.7%, SSE 9.2%, SE 8.8%--but sizes rarely exceed 1m (3ft). Ideal wind is stuck at 5%. Tropical cyclones can still produce rare S/SW swell, but the accompanying wind and rain usually make for a chaotic session. With water at 29.4C and air around 27.7C, August is best spent waiting for the monsoon to break.
