The Lowdown
Imperial Text:
Alright, let’s break it down in feet and miles per hour.
Tuesday, August 11th kicks off a beaut. The morning is glassy with a light 3 mph wind from the SSW, pushing a clean 7 ft south swell. The water temp is about normal for the season. The energy is a strong 1277. This is a real standout for the intermediate surfer; that 12-second period gives it some welly. The afternoon holds up just as well with a 7 ft south swell and glassy 3 mph from the NE.
Wednesday the 12th is a write-off. The wind goes cross-on from the NNE at 9-12 mph, making it choppy despite a 6 ft swell. Not worth your time.
Now, Thursday the 13th is the one for the experienced surfer. We’ve got offshore 6 mph winds from the SW and a 7 ft south swell with a long 14-second period. The energy is huge at 1599. It’ll be clean and powerful, too big for beginners. This is the session for the experts.
Friday the 14th gets lumpy again with cross-on winds, though there’s still size around 6 ft. The weekend from the 15th drops off in size and quality, with choppy conditions and a 4 ft swell on Saturday morning. The following week looks pretty flat and ordinary until the 22nd, where we see a tiny glassy 2 ft south swell on Saturday morning – nothing to write home about.
But hang in there. Monday the 24th gives us a hint of things to come. A glassy 1.0 ft SSE groundswell in the morning, then the afternoon builds to a clean 3 ft SSE swell with a very long 17-second period and light cross-off wind.
The big payoff is Tuesday the 25th. That morning, Barrinha is going to be perfect. Glassy, with a 3 mph WSW wind, a 5 ft south swell with a 14-second period, and energy at 1312. This is the one. The afternoon is just as clean. Wednesday the 26th keeps the run going with a clean, offshore 7 ft SSE swell. Get that date marked.

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.
