The Lowdown
Alright, grab your board and listen up. It’s Rusty here.
First thing you need to know: the water is sitting at about 66°, which is pretty much normal for this time of year, so no wetsuit surprises.
We’ve got a slow start for the next couple of days. Wednesday afternoon and Thursday are a write-off with tiny, weak, and messy waves. The combined energy is barely a whisper, so don’t bother. Friday afternoon is where it starts to get interesting. The swell jumps to about 7ft from the south with a 9-second period, pushing the energy up. The wind is a cross-off, keeping things clean, but the short period means it’ll be a bit fat and crumbly.
Now, Saturday morning on the 22nd is the first real standout. We’ve got nearly 8ft of south swell, energy is pumping, and it’s clean with gentle cross-off winds. This is proper size, so it’s for the intermediate crew at Barrinha. The swell direction is almost exactly from the south, which is bang on the optimum for this spot. Sunday morning holds at about 6ft with a longer 11-second period, giving it better shape, and light cross-off winds.
But the absolute best of the run is Monday morning, the 24th. This is a serious session. The swell is nearly 8ft from the south, the period stretches to 13 seconds, and the combined energy is massive. The wind is dead calm, glassy as a mirror. This is big, powerful, and clean. It’s expert territory at that size, but if you’ve got the skills, this is the one. The longer period will make the waves punchy, and Barrinha is a fairly exposed spot, so it’ll cop the full force.
After that, the quality drops. Tuesday through Thursday get choppy with cross-onshore winds, and the energy fades. You’ll get a small window on Wednesday morning, the 26th, with about 4ft and glassy conditions, but it’s not the same beast. The rest of the run into early September is a mix of tiny, weak, or messy conditions. The 3rd of September has a brief pulse of about 5ft from the northeast with offshore wind, but the period is a short 6 seconds, so it’ll be bumpy and weak.
Overall, the clear winner is Monday the 24th morning. Get it while it’s good.
Rusty.

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