Conditions at Troia in August
August: Short-Period Sideshore Summer Surf
August is nearly identical to July, with an average swell height of 3-3.5ft (1.0m) and a period of 9.1s. NW swell again owns the rose at 66.2%, with WNW at 24.4% and W at just 3.8%; SSW/WSW totals are barely half a percent, while W is only 3.8%, so direct preferred swell is extremely scarce. Wave heights are concentrated between 2-3ft (0.5-1m) and 3-5ft (1-1.5m), making for fun, small, rippable waves when the wind allows.
Wind is the deciding factor: NNW still leads at 45.7%, with NW at 17.9% and WNW at 9.1%. Ideal conditions tick up slightly to 31%, mostly on lighter mornings. This is the warmest month for air (23.6°C average) with water reaching 17.8°C and virtually no rain (0.17mm/day). It's not about power at Troia in August; it's about small summer barrels, soft shoulders, and staying patient for the autumn change.
