The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s on the cards.
It’s a bit of a tough outlook, to be honest. There’s swell coming, but the wind is going to be a pain for most of it, keeping things choppy and messy. The water is about average temp for the time of year, so nothing to worry about there. The first real chance at a decent wave doesn’t pop up until Monday the 24th.
La Barra (point/river) is the only spot in the mix. It’s fairly consistent, which is a good sign, but we’re going to have to sit through a lot of slop first. Friday the 21st through Sunday the 23rd is a total write-off—strong winds, lumpy, poor conditions. The swell energy is moderate to strong, getting up to 3800 on Sunday, but with cross-onshore winds, it’s not worth paddling out.
Monday the 24th is the first glimmer of hope. The wind swings light onshore from the SSE, and the swell is a solid 6ft from the SSE at 13 seconds. Energy is high (1139). It’s marginal, but with light wind and a decent groundswell, it could be a goer for the more experienced surfers. The short period stuff on the 4th and 5th of September is weak, so don’t plan around that.
The standout is probably Tuesday the 25th. We get a clean, cross-off breeze from the NE, swell is a manageable 4ft from the SSE, and the energy is moderate (456). It’s clean, the wind is right, and it’s your best shot for a few smooth waves. Wednesday the 26th is similar, but a touch smaller. After that, it drops right off. There’s a long gap from the 28th of August through to the 2nd of September with very little going on.
The 2nd of September is interesting. Glassy conditions in the morning with a small 3ft easterly swell. That’s about as good as it gets for the second week. The energy is weak (217), but glassy is glassy. The crowds are listed as sometimes, so you might have a few others out, but nothing to worry about.
So, the pick of the fortnight is Tuesday the 25th at La Barra. Clean, cross-off wind, and a solid 4ft SSE swell. Monday the 24th is a backup if you want more size and can handle the light onshore breeze. The second week is flat and uninspiring, with the 2nd of September being a very small, glassy consolation.
Rusty.

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. If you surf the same spot (La Barra) 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 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.
