Conditions at Pichilemu in August
August: Anticipating Spring
August continues the winter pattern but with a subtle shift toward more SW in the swell and a slight improvement in wind. The average swell height is 1.7m (5.6ft) and the period stays at 12.5s, while SW swell increases to 28.9% and WSW settles at 49.3% - the most balanced winter mix of the year. There is still a decent amount of 2-2.5m (6.6-8.2ft) swell, with some XXL lines on the fringes. Ideal offshore wind improves to 64%, as the S/SSW winds (16.5% and 17.6%) remain dominant, but NNE (8.7%) and NNW (7.5%) can still ruin the lineup for days at a time. The coldest water of the year at 12.2°C and air temps around 10.0°C with 2.08mm/day of rain mean it is still winter, but late-month swells often come with a touch more southwest in them and a feeling that clean season is around the corner.
