August: Tropical Swell and Reliable Mornings
August carries the summer swell torch with an average wave height of 5ft (1.6m) and a long period of 13.4s. The swell direction is dominated by SSW at 54 percent and S at 36 percent, so nearly all the open ocean energy is aimed at the beach. The 1.5-2m band remains loaded - the S and SSW totals for that class alone reach around 42 percent of all waves - meaning Rio de Coyula is seeing consistent head-high-plus, rippable surf.
Ideal wind conditions come in at 59 percent, with light NW/NNW offshore flow dominating the early hours. E/SE cross-shore flow becomes a player in the middle of the day, but it rarely exceeds 10-20kph. Water temperature peaks at 30.4°C, air at 29.3°C, and rainfall is high at 6.38mm/day as the tropical monsoon season continues. As long as you are willing to share the water with warm tropical energy, August delivers some of the most dependable surf of the year.
