Conditions at El Porto in July
July: Peak Summer Smallness and the Afternoon Onshore Battle
July delivers some of the smallest and least consistent surf of the year, but also some of the longest period summer swells. Average swell height is 2.5-3ft (0.8m) with a 12.7s period. The directional mix is dominated by SW at 39.3% and WSW at 37.7%, with SSW contributing 14.0% and W just 8.6%. That is a classic Southern California summer mix: southern-hemisphere and tropical-origin swells arriving long and clean but small. Surfable 2-3ft (0.5-1m) waves are common, while 3-5ft (1-1.5m) surf remains scarce.
Ideal wind is at its annual low, 24% of the time. The wind rose is dominated by SW and WSW flow, with those directions together above 38%, so surface conditions deteriorate quickly through the day. What quality exists comes in the early morning under lighter winds. Air temperature averages 23.1°C, water temperature is 17.0°C, and precipitation is only 0.07mm/day. Summer surf at El Porto is more about longboard days and fun shoulder-high runners than steep winter walls; low expectations plus dawn patrol is the move.
