August repeats July's numbers and adds the crowd. The alisios are still running, the swell is short-period when it comes at all, and the north shore reefs stay off because they never get their twelve seconds.
The islands themselves are full: this is the peak of the European holiday season, and the beach breaks that were quiet in April now have families on them. That is not a reason to stay away if you are learning, because a soft, waist-high wave on sand with 23°C water and boardshorts is a good place to spend a week. It is a reason to be honest about what the trip is. Get in early, stay near El Cotillo or Famara, and treat any clean afternoon as unexpected.
