Conditions at Itacoatiara in August
August: Strong South Pulses, Drying Out
August is the last full month of reliable winter groundswell. The averages hold at 4.5ft (1.4m) and 10.8s, with S at 26.6%, SSE at 23.2%, SE at 17.5%, and ESE at 16.8%. The SSW window remains relevant at 7.6%, so solid S/SSW pulses are still on the schedule. There is plenty of size: S produces 9.9% in the 5-6.5ft (1.5-2m) class and 4.5% in the 6.5-8ft (2-2.5m) class, while SSE and SE add plenty of shoulder-to-head-high waves. Ideal wind drops slightly to 60%, but the ENE trade flow strengthens to 25.6%, making the shape fairly clean most days. It is the driest month at 1.55 mm/day, and the water cools to 21.1°C, so bring the rubber; the more exposed surf will reward those willing to earn it.
