The Lowdown
Alright, let’s talk about what’s coming up in feet and miles per hour.
Straight up, this 16-day window starts with a long, flat spell. From Monday the 24th of August through the end of the month, it’s mostly junk. Small swell, bad wind, or both. You’re looking at a full week of nothing worth chasing. That kind of blank run isn’t unusual for this area.
Things finally wake up on the 1st of September. Tuesday morning brings a big pulse – 10ft swell from the SSW, period 10 seconds. That’s a lot of energy (3100 combined). But it’s too big for Barrinha. The break just can’t handle that size well. The wind is offshore from the SSW at 12 mph, so it would be clean, but that wave is only for experts, and even then it’s risky.
Tuesday afternoon drops to 8ft from the S, period 12 seconds, but the wind goes cross-shore from the SSE at 12 mph, so it gets a bit choppy.
After that, it fades out again. There’s a decent enough morning on Sunday the 6th of September – clean 5ft from the SSE, cross-off breeze from the SSW at 9 mph. Rideable, but not a standout.
The real winner is Monday the 7th of September morning. Glassy flat calm, no wind, and a clean 6ft swell from the SSE at 12 seconds. Combined energy is 969 – moderate but good shape. That’s the morning to be out. Light rain, but it’s glassy, so who cares.
So the best call is Monday the 7th of September morning at Barrinha. Clean, glassy, chest-to-head high waves from the SSE. That’s your one true window.
Water temp is about 66°, right where it should be for this time of year. Nothing unusual.

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.
