The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line at La Barra.
We’ve got a solid run of surf on the cards, kicking off this Friday morning. The first standout is actually the whole stretch from Friday 28 August right through to Sunday 30 August. The mornings are where it’s at. The swell is already on the way with a nice 2ft to 4ft, all coming from the SSW, and the key here is the wind – dead calm, glassy conditions. Combined wave energy is moderate to strong, so there’s plenty of push. The water temp is sitting around 88°, which is a touch warmer than normal for this time of year, so you can leave the steamer at home. The river/jetty setup at La Barra was made for this kind of long-period groundswell, with periods between 14 and 19 seconds. That means better-shaped, powerful lines but longer waits between sets. The direction is spot on for the break’s optimum. Expect clean, lined-up waves with no crowds to speak of first thing. The afternoons get choppy as the SSW wind picks up, so make sure you’re in the water early.
Moving into Monday 31 August and Tuesday 1 September, the swell drops a touch to 3ft, but the mornings still deliver with glassy or near-glass conditions. The crowds might show up sometimes, but consistent quality is on offer. The highlight is definitely Saturday 5 September morning. That’s the standout of the whole outlook. We get a clean 5ft SSW swell with a 16-second period, calm wind, and strong combined energy. This one’s a little chunky, so it’s better suited for experienced surfers. It’s the best push we see in the whole window.
After that, there’s still a steady run of clean mornings with 4ft to 4ft SSW swell right up to Monday 7 September, though it gets a bit smaller toward the end. The second week from 8 to 12 September offers more of the same rhythm: smaller morning swells around 2ft to 4ft, all SSW, with glassy or offshore winds. Nothing huge, but consistent and rideable. If you can only get out once, aim for Saturday 5 September morning. That’s the one.
Rusty.

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.
