The Lowdown
Alright, my friends, Rusty here with the lowdown on La Barra for the next couple of weeks.
The first few days are a bit of a dud, with small, weak swells and onshore breezes making a mess. The water is a warm 88°, which is a touch above average for this time of year—nice for a long session.
Things pick up on Friday, August 28th. The morning is a real beauty. We’ve got a 2-foot SSW swell, but the real magic is the 19-second period. That’s a long, powerful groundswell. The energy is moderate (571), and the wind is glassy. The waves will be clean and lined up, perfect for this river/jetty spot.
Saturday, August 29th morning is even better. The swell is up to 4 feet, still from the SSW, with a 16-second period. The energy jumps to a strong 855, and the wind is dead calm. Glassy, clean, and with some real push—this is the best of the first week. You might see a few other folks out there, but it’s worth it.
Sunday morning, August 30th, is still solid, with a 4-foot SSW swell, but the period drops to 14 seconds and the wind is cross-off from the NW. Clean, but not as perfect as the glassy days.
Now, for the real gem. Look at Friday, September 4th, morning. This is a ripper. We’re talking 4 feet of SSW swell, 17-second period, and glassy conditions. The combined energy is a massive 1123—that’s powerful, high-quality surf. This is a long-period groundswell, so it’ll be well-shaped and powerful, and for a river/jetty, it’s going to be a dream.
And then Saturday, September 5th, morning. This is the absolute standout of the whole forecast. 5 feet of SSW swell, 16-second period, and glassy winds. The wave energy is 1234—very strong. This is a serious session. The size is getting up there, so it’s for the experienced crew. Beginners, stay on the beach. The conditions are pristine.
After that, the surf slowly backs off through the second week, but the mornings stay glassy and clean, with solid waist-to-chest high waves. The 9th of September morning has a beautiful 3-foot, 18-second groundswell—long period again, but smaller, making for a really fun, clean day.
So, the absolute best is Saturday, September 5th, morning. Massive energy, solid size, and glassy. Friday, September 4th, is a close second. Don’t miss the 28th and 29th either.
Rusty out.

Information about the La Barra Surf forecast
The above surf forecast table for La Barra provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Barra can be found by selecting the local surf guide option on the grey menu. Our La Barra 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.

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 Barra 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.
