Conditions at Murtosa in August
August: Small Pulses and Sea-Breeze Chop
August remains stuck in the summer pattern, but there are slight signs of life compared to July. The average swell height stays at 1.4m (4.6ft) and the average period rises modestly to 8.9s. NW still dominates the wave spectrum at 45.9%, with NNW at 28.5% and WNW at 18.3%, but again much of this is shorter-period, locally forced surf. The 1-1.5m (3.3-4.9ft) class is the most common, and there are still some fun-sized 1.5-2m (5-6.6ft) waves from NW. The wind situation remains poor for grooming: NNW winds are 48.9% of observations, NW adds 14.2%, and ideal surfing winds are only 11% of the time. The Azores High keeps conditions locked in a summertime heat, with air temperatures averaging 21.2°C, almost no rain (0.61 mm/day), and water temperature peaking near 17.5°C. If you want clean waves in August, check dawn or wait for a rare E/SE offshore event.
