The Lowdown
Alright, Rusty here. Let’s get into what this stretch of coast is serving up.
The pattern starts a little ragged, but there are a couple of truly sweet windows if you’re patient. A few days of waiting, then some absolute glassy perfection mixed with heavier, expert-only juice later on.
Monday morning the 7th gets things rolling. You’ve got a 6ft south swell with a nice cross-offshore breeze, so it’s clean. Wave energy is moderate to strong at 551, so there’s some grunt in the water. Not the best of the period, but it’s a solid start.
Wednesday morning the 9th is where the magic starts. Barrinha goes glassy—absolutely flat calm, no wind—with a clean 4ft south swell. The ocean is like a mirror. The water temp is pretty normal for the season, nothing crazy. This is a perfect small-wave session.
Thursday afternoon the 10th is another clean one. The swell stays around 4ft, but the period jumps to 15 seconds—proper groundswell—and the energy climbs to 513. Cross-offshore breeze keeps it clean and lined up.
The absolute standout, the one you write in pen, is Monday morning the 14th. Completely glassy, no wind, and a solid 7ft south-southeast swell. The energy is huge at 994, so it’s powerful and well-formed. This is for confident intermediates and up. Crowds can show up here sometimes, so you’ll want to be early.
Thursday morning the 17th is another top pick. Clean cross-offshore wind, a 6ft south swell, and energy at 827. The period is a shorter 8 seconds, so it’s punchy and a bit steeper, but clean winds make it a good time. Water temp is still sitting about average.
Into the second week, things get messy. Friday the 18th throws size—8ft from the south with a long 12-second period—but the wind turns cross-onshore, which kills the surface. The energy is massive at 1631, but only for experts in poor conditions. Saturday the 19th is a total washout with choppy onshore breezes.
From Sunday the 20th onward, it fades fast. Small, weak swell and moderate winds. By Monday the 21st, it’s almost flat. A long dead spell after the 18th.
So the winners: Monday the 14th is the clear champ—glassy, heavy, and clean. Wednesday the 9th for a glassy, small-wave groomer. And Thursday the 17th for a punchy, clean morning session.
Aim for that Monday the 14th.

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.
