Conditions at Penarronda in August
August: Warm Oceans and Marginal North Swell
August looks a lot like July, with a slight bump in energy. Average swell height is about 3ft (0.9m), average period is 8.9s, and the direction distribution remains locked on NW and NNW - 37 percent each. The northern Atlantic is quiet under a stubborn ridge of high pressure, so most of the energy is small and short-period.
Ideal wind is only 20 percent, so clean summer surf is rare. S/SSW/SW offshore flow is present about 14 percent of the time, while NE and ENE winds dominate the wind rose and tend to mess up the surface. Water temperature peaks at 20.0°C, air temperatures average 19.2°C, and rainfall is 1.37 mm/day. August is all about warm-water, small-wave groveling. A dawn patrol with a longboard and zero expectations is the best bet.
