July: The Summer Doldrums in Full Effect
Welcome to the true doldrums of the Basque surf calendar. July sees the average swell stuck at 1.0m (3ft) and the period dropping to 8.8s - the shortest average of the entire year, sitting right on the boundary between average and messy. The swell direction remains stubbornly northwestern (NW 65.3, WNW 16.4, NNW 16.4), but it is a low-energy version of the winter dream. The wind pattern is the biggest obstacle: NNW leads all directions at 19.1 percent, NW follows at 14.6 and WNW at 12.6, meaning more than half of the month's wind comes from the worst possible quadrant. Offshore winds are nearly absent - S 2.5, SSW 2.3, SW 2.4 and WSW 4.0 - leaving the ideal wind score at its yearly low of 18 percent. The afternoon thermal onshore flow is relentless, and even when a small NW groundswell lines up, the chop and wind texture often wreck it. Air temps reach a pleasant 20.0°C and water temp holds at 21.6°C, but for true quality surf at Zurriola in July, you are chasing a ghost. Longboard season is officially here.
