The Lowdown
Alright, crew, Rusty here. Let’s talk about what’s coming up.
We’ve got a nice run of SSW swell on the cards, with a few absolute gems if you time it right. The water’s sitting at 86°F, which is a touch warmer than normal for this time of year – so ditch the wetsuit.
First real chance to get wet is on Friday morning, August 28th, at La Bocana (Rio-Grande-La-Bocana). It’s a river mouth, which means it’s inconsistent, and it loves a direct SSW swell. The swell is a modest 3ft, but it’s packing a 16-second period – that’s proper groundswell, with a lot of energy underneath it. The wind is glassy, blowing from the NE at 3 mph, so the surface will be like a mirror. The combined energy is moderate at 749. It’s a beginner spot, so that size is perfect for a fun session. Crowds are possible, so get down early.
The real standout is Saturday morning, August 29th. The swell bumps up to 5ft out of the SW, still with a long 16-second period, and the wind is absolutely dead calm. The wave energy is strong at 1133. This is going to be the session of the run. It’s a bit much for total beginners, but for anyone with a bit of experience, it’s going to be cracking. The swell direction is exactly what this spot needs.
Sunday morning, August 30th, is very similar: 5ft of SSW swell, glassy, calm winds, and strong energy at 902. The period is a slightly shorter 14 seconds, so the sets will come through a bit more regularly. Another top morning.
The first week has a few other good mornings. Monday, August 31st, and Tuesday, September 1st, are smaller, around 3ft to 4ft, but with glassy winds and good shape. Perfect for a longboard.
The next big one is shaping up for Friday, September 4th. The swell climbs back to 5ft from the SSW, with a 17-second period – that’s very long period. The energy is very strong at 1357 in the morning. Both the morning and afternoon are glassy, with light winds. It’s a long way out, but it’s looking like a potential classic. It’s over 5ft, so it’s for the experienced crew.
Saturday, September 5th, holds the size at 5ft, with a 16-second period. The morning has a light cross-off breeze, keeping it clean. This is another one for the experts.
After that, the swell backs off a bit, but the mornings from September 6th through to September 11th are all showing glassy conditions and swell in the 3ft to 4ft range. The best of the later run is Thursday morning, September 10th, with 4ft SSW swell, long period, and strong energy at 1026.
The two to circle on the calendar are Saturday, August 29th, and Friday, September 4th. Get those dawn patrols locked in.
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.
