August: Longest-Period Groundswell
August brings the most consistent long-period groundswell of the year, with the average period peaking at 13.3s and average swell height sitting at 2.7m (8-9ft). The west-northwest exposure sees more WSW energy than any other direction besides SW, and the W/WNW/NW swells provide some of the year's best raw swell angles.
Yet August is also a windy month. W, WSW, WNW and NW winds combine for a large portion of the wind rose, and ideal surfing wind remains pinned at 17%. This creates a classic winter setup: grinding size and power, but a break that is frequently compromised by onshore storm surf. Air temperature is a cool 15.5°C, water temperature drops to 17.6°C, and rainfall is still significant at 3.12 mm/day. Look for the cold fronts to clear out and the pressure gradient to relax - that's when Injidup turns on.
