Conditions at Blue Bowls in August
August: Peak SSE Swell and Fighting the Onshore Wind
August is defined by the strongest concentration of SSE swell of the year - that direction accounts for 56% of all wave energy, with S adding another 35%. Average height remains 1.7m (5-6ft), period is 11.1s, and the bulk of wave heights sit in the 1.5-2m (5-6.5ft) range, while about 9% reaches 2-2.5m (6.5-8ft). The problem is wind direction: SE (11%) and SSE (13%) winds are common and are onshore/cross-onshore at Blue Bowls, creating lumpy conditions on otherwise solid swell days. Clean windows come when WSW (10%), W (9%) and WNW (7%) winds take over; ideal wind sits at 41%. This is a month for picking the windows and not just the swell charts. Expect strong, powerful south-southeast reef surf with some hollow 6-8ft (1.8-2.4m) sets when the angle and wind line up. Rain is about 5.57 mm/day and water temp is 29.4°C.
