Rio de Coyula - surf spot statistics

Rio de Coyula in Mexico offers consistent surf conditions year-round, with ground swell dominating the wave energy in every month. The best months for surfers are typically from June to October, when the mean swell size peaks at 1.5–1.6m, offering more powerful waves. During this period, ground swell remains highly prevalent (93–96%), ensuring clean and well-organized waves, while wind conditions gradually improve, with the highest chance of favorable winds (good wind conditions at 39–45%) occurring from July to November. The worst wind conditions are in April and May (only 35–36% good winds), though swell consistency remains strong. Swell size is smallest in December–February (1.1–1.2m), making these months better suited for beginners or less demanding sessions. Overall, the summer and early fall (June–October) provide the most reliable combo of decent swell and cleaner winds, making them the prime window for advanced surfers seeking optimal conditions. However, due to the persistent onshore winds (bad wind conditions remain above 55% year-round), patience and timing are key for scoring the best sessions.
