Conditions at La Jolla in August
August: Southern-Hemisphere Groundswell with Moderate Wind
August continues the summer pattern with S swell at 55.3 percent and SSW at 30.7 percent, supported by an SSE component of 8.3 percent. The average period remains long at 13.5s, and the average height sits at around 4.5ft (1.4m). Many days produce 4-5ft (1.2-1.5m) lines, with bigger pulses when tropical storms or southern-hemisphere systems send stronger energy into the region.
Ideal wind is 47 percent, similar to July, and the wind roses show a lot of light NE/NNE flow rather than strong offshore winds. Water temperature peaks near 30.6°C, the warmest of the year, and precipitation is high at 5.48mm/day. The humid tropical air can make the surf feel a bit sluggish, but the long periods still offer plenty of rideable waves for an east-facing spot that has no true westerly swell window.
