The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The first bit of the outlook is a bit rough, but we’ve got a solid run of surf coming in the second week that’s worth getting excited about.
Okay, so the first few days are a write-off. From Saturday the 1st through to Monday the 3rd, the swell is tiny and the wind is a mess. You’re looking at a lot of cross-on breezes and barely any rideable bumps. Honestly, it’s a gap of about three days where you’re better off doing something else. The water temp is sitting at 66°F which is pretty normal for this time of year, nothing wild.
Now, things start to look up on Tuesday the 4th. The wind goes glassy, a light 3 mph from the NNW and SE through the day, and the swell picks up a bit. We’re seeing a 3ft to 3ft S swell with a 11-12 second period, and the combined energy gets up to 243. It’s not going to blow your mind, but it’s surfable and clean. This is just a warm-up, though.
The real standout is a full week later, on Tuesday the 11th of August. This is the one. Barrinha (your local spot) will be firing. We’ve got a solid 8ft S groundswell rolling in with a very long 15 second period. The combined energy is a massive 3094, so there’s plenty of power. The wind is light, cross-off from the SSW at 6 mph, making for clean, well-shaped waves. This is excellent surf for experienced surfers only—this size is way too big for beginners. Expect a proper, powerful groundswell that will be working best at this point break setup.
The day before, Monday the 10th, also has a big swell building (8ft to 10ft from the S, 13 seconds), but the wind is cross-on and choppy, so it’s not as clean. The 11th is the pick.
Following that, Wednesday the 12th and Thursday the 13th still offer good, clean conditions with S swell dropping from 6ft to 5ft, light winds, and clean faces. The energy stays strong (925 down to 517). Still very surfable and fun.
The rest of the second week, from Friday the 14th onward, the wind turns ugly again with cross-on breezes, and the swell holds around 4ft but the quality drops out. The 16th has some clean cross-off wind but the swell is smaller and the energy is lower.
So, to wrap it up: Tuesday the 11th of August is the absolute standout. Mark it down. Clean, powerful, and for the experienced crew only.
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.
