Spot Overview & Description
Tucked just off Mex 200, a dusty dirt track leads you to the windswept shores of Laguna Boca Vieja, where the eastern headland unfurls a classic sandy pointbreak. Rio Coyula offers a rare two-way dance—both left and right lines peel off the point, with the right-hander being the main draw for those who favor a go-right groove. This slice of coastline sees surprisingly light crowds, making it a quiet refuge for surfers looking to trade peak-season hustle for uncrowded takeoffs. The wave here is a creature of the S-SE swell window, though a solid W swell can also spike things into life. Optimal conditions come with swell in the 3-foot range (about 1 meter), breaking over an uneven mix of reef and sand that keeps the lineup interesting. For the cleanest shape, aim for low to mid tide and a crisp north wind. The setup is best suited for intermediate surfers—beginners will find the shifting bottom and occasional punchy sections a tough classroom. While the overall surf potential is moderate, with a mix of quality days and days best left for exploring the lagoon, Rio Coyula is a solid wildcard. When the stars align, you’ll find fun, rippable waves in an atmosphere that feels miles away from the typical Mexican surf scene.
Best Surf Season & Climatology
Best Surf Season (May - September)
The heart of the south swell season arrives in May and continues through September as powerful storms in the Southern Hemisphere generate long-period groundswell that march thousands of miles north to consistently hit Rio de Coyula's south-facing beach. Average wave heights settle in the 1.5-1.7m range with periods well above 13 seconds, delivering solid, rippable waves day after day. The offshore wind regime prevails, with the North Pacific high-pressure system dominating and funneling clean N to NW winds across the break. This is prime time for surfing.
Fair Surf Season (October - February)
As the Southern Hemisphere storm track weakens, average swell heights drop to around 1.2-1.5m, but the wave period remains long (12-13s), keeping the surf quality high. The dominant swell direction remains from the SSW-SW, though occasional pulses of ENE background swell from distant North Pacific fronts add variety. Offshore winds are still frequent, especially in November and December when the continental high pressure sets in. While the surf is smaller, it remains fun and grovel-worthy on the better days.
Low Surf Season (March - April)
The transition months of March and April see a dip in both swell consistency and wind reliability. The average wave height holds around 1.4-1.5m, but the percentage of favorable offshore winds drops to its lowest annual levels (44-47%). The typical pattern involves a battle between lingering winter winds and building summer breezes, often resulting in onshore flow from the south. Still, occasional long-period SSW groundswell can reward those who pick the right day, offering punchy, clean waves when conditions align.
