The Lowdown
Alright, let me tell you what's shaping up here.
It's a bit of a slow start, but there's some real promise on the horizon. The water is sitting at about 68°, which is a touch warmer than normal for this time of year, so you can leave the 4/3 at home for a bit.
First up, Tuesday morning the 4th of August is looking like a glassy little dawn patrol. Swell is a tiny 3ft from the South with a long 12-second period, and the wind is dead still. It's nothing heavy, but it'll be clean. The combined energy is moderate (301). Later on Tuesday, the wind picks up a little, so that morning window is the one.
Now, we have a bit of a quiet spell after that. Wednesday is small and messy, Thursday is tiny, and Friday is small but clean. The real action starts to build on Saturday the 8th of August. That morning, we see a jump in size to 6ft from the South, with a very long 15-second period. The combined energy is strong (1473). But, the wind is a cross-onshore, so it's going to be a bit bumpy. This one is for the crew who don't mind a bit of chop for some proper power.
The standout window is the following week. Tuesday the 11th of August afternoon is a beauty. The swell is a solid 6ft from the South, 11-second period, with a light offshore wind. The combined energy is strong (747). It's clean, it's got push, and the water will be glassy. This is the one to circle on the calendar.
Then, on Friday the 14th of August, we get a proper pulse. Both morning and afternoon are seeing 7ft of South swell, clean and lined up. The combined energy is very strong (1087 in the morning). This is expert territory, over 8ft. It's big, powerful, and with a long period, it'll be grinding down the point. If you've got the skill and the board, this is the session.
After that, things get a bit mixed up again with onshore winds and lumpy conditions, but there's a final chance on Tuesday the 18th of August with a clean 5ft from the SSW and a light offshore wind.
So, the honest truth? The best of the best is that Tuesday the 11th afternoon for clean, solid waves, and the Friday the 14th for the big-wave crew. Get on it.

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.
