Conditions at Itapiruba in August
August: Strong Cross-Shore, Solid Swell
August is a transition month inside the winter season. The swell is still excellent - average height 5-6ft (1.7m), period 9.4s - but the ideal-window percentage drops to 51% as the trade winds regain some strength. Swell from ENE (15.8%), E (12.4%), SE (11.8%), SSE (11.5%), and S (14.5%) keeps the beach well supplied. The NE quadrant is also more prominent than in June-July, with NE at 12.1%, adding a shorter-period component to the lineup. The 5-6.5ft (1.5-2m) range is still the biggest class, and there is a good amount of 6.5-8ft (2-2.5m) energy from S and ESE.
Wind is where August backs off a notch. NNE dominates at 28.3%, and NE adds 11.1%, so cross-shore flow is often strong, especially in the 20-30kph class. SSW (11.6%) and SW (11.0%) still offer relief, but the clean windows are less frequent than in May-July. Water temperature bottoms out at 17.3°C, air sits at 17.2°C, and precipitation is low at 3.11mm/day. On the right day - usually right after a frontal passage - August can still deliver crisp, powerful winter waves.
