August: Summer Flatline, Forgotten Windows
August is nearly identical to July in terms of wave size. Average swell height stays at 1.4m (4.6ft) and the period creeps up only slightly to 9.0s. The directional distribution remains stuck in the northwest: NW (39.6%) and NNW (32.4%) dominate, with WNW (18.9%) and W (4.4%) far behind. The ocean runs on a diet of distant low-pressure storms far to the north and local windswell; there is no real consistent groundswell. For a beach that needs W/SW/WSW energy, this is the hardest month to find quality waves.
Ideal offshore winds improve slightly to 36%, but the main wind is still NNW at 39.0%. The thermal pattern is fully established, producing daily onshore winds from late morning onward. Sunrise sessions are your best bet, especially when a synoptic-scale high slides far enough east to allow an offshore easterly airflow over the Iberian Peninsula - those days turn the ordinary summer peaks into fun, hollow beach break waves. Air temperatures peak at 20.9°C, water temperature is a comfortable 16.9°C, and precipitation is a mere 0.89 mm/day. August surf is about making the most of small clean windows, not epic swell.
