Conditions at Ciruelo in August
August: Powerful SSW Swell, Persistent Afternoon Onshores
August is a frustratingly good month for swell. The average period holds at 13.5s and the size stays around a fun 1.1m (3.6ft), but the directional picture is almost entirely SSW at 93.6%. The open-ocean fetch is vigorous and Ciruelo's SSE-facing banks receive plenty of long-period energy. When the surface is clean, these are some of the most powerful and rippable waves of the Central American summer.
The challenge is the daily wind swing. Ideal surfing time is 62%, and the NNW/NW/WNW quadrant contributes around 29% of the wind, so dawn patrol often delivers clean, groomed lines. As the day progresses, SW and WSW sea breezes take over - the combined SW/WSW/W flow is nearly 35% - and the surf becomes bumpy. Rain averages 9.51mm/day, air temperature 26.8°C, and water temperature 28.8°C. Be ready to surf early and get skunked in the afternoon.
