July: The Summer Lull
July is the height of the summer lull at Long Beach. The average swell height drops to 3.9ft (1.2m) and the period holds at 11.4s, but the energy is the weakest of the year. Directionally, the swell window could not be better: W (39.8%), WSW (30.6%), SW (13.3%) and WNW (11.8%) combine for over 95% of all wave observations. The problem is a relentless NW-WNW wind pattern: WNW winds blow 41.8% of the time, W adds another 17.0%, and NW 8.4%, while offshore NE to ESE winds are almost nonexistent at 4.2%. Ideal conditions are just 13%, the lowest of the year. Water temps max out around 14.0°C, air temps average 14.6°C, and precipitation is only 1.59mm/day. For the surfer, July is about micro-sessions and longboard friendly lines: think waist-to-chest-high, wind-affected waves with the occasional glassy dawn. Look for early mornings and pay close attention to the W wind.
