The Lowdown
Alright folks, let’s talk about the stretch ahead for Barrinha. It’s a bit of a tough start, but there’s a real gem waiting for us if we’re patient.
The first ten days or so look pretty grim. We’ve got some tiny swell bumping around, but the winds are all over the place, mostly cross or cross-on, and the energy is just pathetic—barely breaking 200 (combined energy). The water temp is sitting right around 66°, which is dead average for this time of year, so at least you won’t be freezing while you’re sitting there waiting for a wave that never comes. Honestly, for the first week and a half, it’s a write-off. There’s a long gap here with no real surf on offer.
Now, hold onto your board. The real story starts on Monday, August 10th. The swell starts to build, but it’s a bit messy that day with onshore wind. The energy jumps up to 1165 (combined) and the swell is 5ft from the south with a very long 15-second period. That’s a proper groundswell. It’s going to be a bit too much for beginners at that size, and that long period might make it break a bit straight at the beach, but keep an eye on the banks.
The absolute standout is Tuesday, August 11th in the morning. This is the one. The forecast has the winds going totally glassy, and the swell is still a solid 5ft from the south with a 14-second period. The energy is pumping at 818 (combined). This is clean, powerful, good quality surf. It’s not for the faint of heart—that’s expert territory—but if you’ve got the skills, this is the best session on offer. It’s a long-range call, so don’t get married to it, but it looks promising. The afternoon gets a bit onshore, so make it a dawn patrol.
The days after that settle back down to smaller, less interesting conditions. The wind creeps back onshore and the swell drops. So, if you’re keen, pencil in that Tuesday morning. Everything else is a skunk.

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.
