Conditions at Oceanside in July
July: Peak Summer, Peak Onshore
July is the deep summer groove at Oceanside. The average swell height is 1.0m (3.3ft), with a very favorable direction mix: SW leads at 47.3%, WSW at 29.8%, and SSW at 17.6%. Southern Hemisphere groundswell provides the energy, and the average period of 13.7s remains in the powerful long-period class. But very little of that energy makes it into the overhead range; the distribution is overwhelmingly focused in 2-3ft (0.5-1m) surf, with some 3-5ft (1-1.5m) sets from SW and WSW.
Wind remains the spoiler. Ideal offshore wind is just 4%, while W and WSW winds combine for nearly half the wind distribution at 26.7% and 20.5%. The afternoon westerly is strong and consistent, making surface conditions lumpy. Water temperature warms to 18.4°C (65.1°F), and air temps reach 20.4°C (68.7°F). Keep expectations low, chase the dawn window, and save your energy for smaller boards or a longboard for the soft summer rollers.
