Conditions at Playa del Castillo in July
July: The Slowest Gear
July is typically the most challenging month for surf quality at Playa del Castillo. The average swell height actually holds at 5.2ft (1.6m), but period compresses to 7.7s, the lowest of the year. The swell window is dominated by N (46.7%) and NNE (25.6%) energy, with NNW at 26.2% and NW nearly absent at 0.2%. Meanwhile, wind blows from NNE a remarkable 65.5% of the time, and ideal wind conditions crater to just 4%. The result is a month of short-period, wind-affected surf that is generally too lumpy to get excited about-unless a rare summer thunderstorm or tropical disturbance lines something up. Air temperatures average 21.9°C, water warms to 22.0°C, and rain is almost nonexistent. Bring the groveler, not the step-up.
