The Lowdown
Alright, Rusty here. Let’s break down what’s coming for us in the local zone. The first few days are quiet, but then we get a proper pulse of swell.
Saturday, August 22 kicks off with some clean, surfable waves at Barrinha. The morning brings a 2.4m south swell with a 10-second period, and a light cross-off wind keeping things tidy. The combined energy is moderate at 1048. It’s a decent size, but the quality is just okay—a bit marginal with the tide. The afternoon drops to 2.1m, still clean, but nothing special.
Sunday, August 23 morning is where it gets good. A 2.0m south swell with an 11-second period, light cross-off wind, and combined energy of 1022. Conditions are set to be very good. The afternoon builds to 2.3m with a 12-second period, but the wind turns cross-shore, so it’s not as clean. Morning is the call.
Monday, August 24 is the big one. Barrinha gets a 3.0m south swell with a very long 14-second period—proper groundswell—and it’s glassy in the morning. Combined energy jumps to 3253, which is strong. This is the session to aim for. But with the swell over 2.5m, this is for experienced surfers only. Beginners should sit this one out. Water temp is 19°, about average for this time of year. Afternoon turns onshore and lumpy, so get out early.
Tuesday, August 25 morning is still fun: 1.9m south swell, 13-second period, glassy again. Combined energy is 1170, and conditions look very good. The afternoon gets blown out by a strong onshore wind, so surf early.
From Wednesday, August 26 through the end of the first week, it’s mostly onshore wind and choppy conditions. Swell hangs around but the quality is poor. A couple of small windows of clean surf show up around August 31 and September 2, with swell around 1.0m to 1.9m, but the energy is low and conditions are ordinary.
Wednesday morning, September 3 gives us a brief return of glassy conditions with a 1.3m south-southeast swell, 8-second period, and combined energy of 319. It’s a small, clean window, but it doesn’t last. The rest of the second week is mostly small, onshore, and not worth chasing.
Bottom line: The standout is Monday morning, August 24 at Barrinha—big, clean, powerful south groundswell. Sunday morning is also very good. After that, the surf drops off and the wind turns ugly. If you’re experienced, you know what to do. If you’re learning, wait for a smaller, cleaner day later on.

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.
