Conditions at Humewood Pier in August
August: Still Heavy, But Winds Begin to Shift
August holds the winter line with an average swell height of 2.4m and a period of 12.2s. SW and SSW dominate again (21.2% and 20.5%), but the S component at 9.7% adds more south in the mix, offering a bit more variety in wave direction. Wave heights still peak in the 2-2.5m range, and there is an ever-present risk of larger sets. The swell is powerful, racy, and demands respect.
Ideal wind nudges up to 21%, as WSW strengthens to 18.8% and W holds at 13.5%. The onshore E/ENE flow is less frequent (E 6.4%, ENE 8.6%), so the clean-window ratio better than June and July. Water temperature reaches the yearly low at 17.4°C, and air temps are a brisk 16.1°C. Late August often feels like a pre-spring transition: the ocean is still alive, but the winds are slowly starting to cooperate. Look for days with a strong WSW gradient to unlock long, grinding A-frames at the pier.
