The Lowdown
G'day, Rusty here. Look, I'll be straight with you—this 16-day window for La Bocana at Rio Grande is a bit of a mixed bag, but there are some proper gems hiding in there if you're patient. We're looking at a river-mouth setup that's exposed to SSW swell, and it's inconsistent, so you gotta pick your moments. The crowd factor is a "sometimes" thing, so you might find some company, but nothing too hectic.
The water's sitting at a warm 86°F at the start, which is pretty normal for this time of year—nothing out of the ordinary there.
Let's run through it. The surf kicks off Sunday the 30th of August with a 5ft SW swell, period 14 seconds, and light SSW breeze. It's rideable, but the tide might be a bit tricky. The combined energy is moderate at 830, but it's nothing to write home about. Then Monday the 31st August morning is your first real standout. It's glassy, with a S wind at just 3 mph, and a 4ft SW swell at 13 seconds. The energy is moderate at 481, but the conditions are clean as a whistle. Expect good surf, and it's one of the better windows for a learner or someone wanting an easy paddle.
The rest of the first week has small waves, mostly around 3ft to 4ft, with cross-onshore or onshore winds keeping things a little lumpy. Not worth rushing out for.
Now, hold onto your board for Thursday the 4th of September morning. That's the real standout in this whole period. We've got a 5ft SW swell, but the period jumps to a very long 17 seconds—proper groundswell. The combined energy is strong at 1432, and the wind is glassy from the W at just 3 mph. This is excellent surf, but it's for experienced surfers. That long period will make the waves peel nicely at this river mouth, but it'll also mean bigger sets and longer lulls. Saturday the 5th of September morning is similar: 6ft SSW swell, 16-second period, glassy NE at 3 mph, and energy at 1412. Another excellent session for the crew who know what they're doing.
After that, the second week settles down. The morning of Sunday the 6th of September is glassy with 4ft SSW swell at 15 seconds—clean, but energy drops to 790. The mornings on the 7th, 8th, and 9th of September offer glassy conditions with smaller swells around 3ft to 4ft. They're decent, but nothing that'll get your heart racing. The 10th of September morning is worth a mention: clear skies, glassy, with a 3ft SSW swell but a very long 18-second period. Low energy at 848, but clean lines if you're keen.
We've got a bit of a lull from the 12th of September onward, with waves dropping to 2ft or 3ft and mostly glassy mornings. Good for a cruise, but not for a proper session.
To sum it up: your best bets are the Monday morning of the 31st of August for a clean, easy session, and the Thursday morning of the 4th of September for something with more grunt. If you're after bigger waves, Saturday the 5th of September morning is your other standout. Don't sleep on those glassy windows.
Rusty out.

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.
