Conditions at Arenillas in August
August: Small Summer Surges and Morning Windows
August remains locked in the summer pattern, with average swell height of 3ft (1.0m) and period of 9.3s. The wave rose shows the same NW/NNW dominance (NW 59.4%, NNW 25.5%, WNW 7.5%), but again the size is severely limited. There is a slight uptick in the 1-1.5m range compared to July (20.2% vs 18.1%), but this is still small surf by Arenillas standards. The wind is slightly more favorable than July, with the ideal wind percentage rising to 24%, but it is still a struggle. ENE (12.1%), E (9.3%) and NE (8.9%) make up almost a third of the wind, which means the surf is often lumpy and onshore. WNW (13.8%) and NW (11.0%) can show up, but as sea-breeze-strength winds they tend to add chop. Water temperatures peak at 22.2°C, air temp averages 21.1°C, and precipitation is minimal at 1.23mm/day. A longboard or a fish is the weapon of choice, and dawn patrol remains the only reliable time for smooth conditions.
