The Lowdown
Alright, Rusty here, checkin' in with the outlook for La Bocana. It’s a slow burn, but there are a couple of moments that’ll get the heart pumping.
This river mouth (Rio-Grande-La-Bocana) is a tricky one. It’s inconsistent at the best of times, and this 16-day window has a lot of days where it’s just not quite on. The water's sitting at a balmy 86°, which is about average for this time of year. The first few days are a write-off, with only small, messy energy on offer. We’ve got to wait until the morning of Thursday the 3rd for something that even starts to look rideable.
That Thursday morning, the 3rd, it flips to glassy, with a 3 ft SSW groundswell running at a long 16 seconds. The energy’s there (725), and those conditions are as clean as it gets. It’s a good sign, but the swell is small, so keep your expectations in check.
Friday the 4th morning is where it really starts to cook. We’re looking at a strong 5 ft SSW groundswell with a 17-second period, pumping in a serious 1366 units of energy. The wind is glassy. This is the standout session. That kind of period from the SSW, at a river mouth, should set up some proper lines. It gets close to 6 ft early Saturday morning the 5th (6 ft), also glassy, with 1405 energy—that’s a big, clean, powerful wave. If you're an experienced surfer, you’ll want to be out there for that Saturday dawn patrol.
A couple more decent mornings pop up, like Sunday the 6th and Monday the 7th, with waist-high swell and glass. But the real standout is that Friday the 4th morning. It’s the best combination of size, power, and absolute perfection.
After that first week, it settles into a pattern of small, glassy mornings. The 14th of September has a tiny 2 ft swell but with a very long 19-second period and zero wind, making for some clean little peelers if you're keen to get wet. Nothing else in the second week comes close to that early run. Overall, for a spot that hits rarely, we’ve got a solid window, but you've got to pick your moments.
Rusty, signing off.

Information about the La Bocana Surf forecast
The above surf forecast table for La Bocana provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Bocana can be found by selecting the local surf guide option on the grey menu. Our La Bocana surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (La Bocana) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for La Bocana may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
