The Lowdown
G’day, Rusty here. Let’s look at La Bocana over the next couple of weeks. Water’s warm at about 86°, dead average for the season, so no complaints.
It starts small but clean. Monday the 31st brings a glassy 4ft of SW groundswell, with a 13-second period – that long period will wrap into the river mouth just fine. Moderate energy at 485, and dead calm wind. Not a standout, but it’s a fun, quiet paddle. Tuesday the 1st is similar: 3ft SSW at 13 seconds, glassy again (428 energy). Wednesday the 2nd morning edges up a touch with 3ft SSW at 13 seconds, still glassy and 572 energy.
The real standout is Friday morning the 4th of September. The swell pushes to 5ft from the SW, with a very long 17-second period and strong energy at 1425. Glassy conditions, and the river mouth can handle that kind of groundswell. It’s getting big for beginners, but for experienced surfers, this is prime. Saturday the 5th morning is nearly as good: 6ft from the SSW at 16 seconds, still glassy, energy at 1411 – that’s expert territory, powerful and clean.
After that, it fades. Sunday the 6th morning has 5ft SSW at 15 seconds, glassy again (958 energy) – very good, just not the peak. The week starting Monday the 7th drops below 4ft, with solid periods but less power. Wednesday the 10th morning offers 3ft SSW at 18 seconds – that’s ultra-long period, so the waves will be clean but slow. By the 12th, it’s back to 3ft ankle-to-waist-high stuff. The 13th is a real low: only 2ft and weak energy at 220. The final days, the 14th and 15th, stay small with long periods; the 15th afternoon gets choppy with a cross-onshore breeze, so skip it.
Crowds are only occasional here, so you’ll likely have the place to yourself, especially on those glassy mornings. La Bocana is inconsistent, but when it fires like that Friday and Saturday, it’s a proper session.
Rusty.

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.
