Conditions at Playa Grande in August
August: Steady SSW Energy with Morning Offshore Windows
August continues the southern-hemisphere swell machine, with the average height at 1.4m (4-5ft) and period easing slightly to 13.2s. SSW is again the engine at 68.2%, but SW contributes a useful 16.0% and S adds 13.9%. August has a slightly larger SW component than July, which helps the swell hit the beach from a more favorable west-southwest angle and improves the shape of the wave.
The wind remains mostly favorable, with an ideal score of 71%. ENE, E, and ESE offshore flow dominates the mornings, but afternoon showers and a lighter sea breeze can create lumpy sections later in the day. Rainfall averages 5.93mm/day, so the surf is often best in the early morning before convection kicks off. Water temperature is warm at 29.2°C. Look for consistent waist-to-head-high waves with occasional bigger sets on the better SW-angle days.
