The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Well, to be straight with you, it’s a bit of a slow start. The first few days are looking pretty lackluster. We’ve got some decent-sized swell rolling in on the 26th, with that southerly groundswell pushing 8ft and a long 14-second period, but the wind is just awful. It’s a cross-onshore breeze that’s chopping it all up, so the wave quality is poor. You’ll be fighting a mess. The combined energy is strong (2152), but it’s not translating into anything rideable. That poor surf sticks around through the 27th and 28th, with the swell dropping and the wind staying on it. There’s a good four or five day gap here where you’re better off doing something else.
Now, things start to get interesting towards the end of the month. On Sunday the 30th, we get a tiny pulse of 3ft from the south, but the real story is the wind. It goes glassy in the afternoon. It’s small, but it’s clean. The energy is weak (56), but it’s a start.
The standout window is looking like the first week of September. Wednesday the 2nd is the one to circle. The morning session at Barrinha is looking prime. We’ve got a clean 6ft southerly swell with a nice 10-second period, and the wind is glassy. The water is about 65°, which is pretty normal for this time of year. The combined energy is moderate (601), and with that offshore wind, it’s going to be smooth and lined up. This is the best on offer, no question. This break is fairly exposed and can get a crowd, so get in early.
Thursday the 3rd morning is also a solid option, with clean 6ft southerly swell and a light cross-offshore breeze. Then Friday the 4th looks good, too, with a clean 5ft southerly swell and a gentle offshore wind. The energy is a bit lower (388), but still surfable.
After that, the swell fades again. We get a couple of glassy and clean days on the 5th and 6th, but with only 3ft to 2ft of swell, it’s not going to be firing. The second week is quiet, with small, short-period, and onshore junk. Not much to get excited about.
So, make your move for the morning of Wednesday the 2nd of September. That’s your best bet.
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.
