July: Peak Offshore Winds and South Swell
July may be the cleanest month of the year at Rio de Coyula. Swell height remains a healthy 5ft (1.6m) and period is 13.7s, while S and SSW swell combine for 91 percent of the directional spectrum - a textbook setup for this south-facing coastline. The inner bar receives constant long-period energy, and with so little unfavourable E/SE swell in the mix, the waves are more organized and more consistent than in the drier months.
The wind is the star in July: ideal conditions hit 62 percent, the joint highest of the year, as NW and NNW winds make up over 27 percent of observations and remain light. That gives Rio de Coyula long stretches of offshore mornings and clean surfaces. Water temperature holds at 30.1°C, air at 29.4°C, and although precipitation remains high at 5.53mm/day, the rain usually waits until the afternoon. July is a serious pick for guaranteed surf in warm, clean water.
