The Lowdown
G’day, I’m Rusty. Let’s talk about what’s coming up for Barrinha, a fairly exposed, very consistent intermediate spot. Right now, the water’s at about 67°, which is average for this time of year, so nothing unusual there.
The next few days are pretty quiet. Sunday the 2nd and Monday the 3rd are small and messy, with weak ankle-biters – swell energy is barely registering (2 to 60). Tuesday the 4th starts looking a bit more promising. Tuesday afternoon the wind goes glassy, and we get a small 4ft S swell with 12-second period, moderate energy (358). It’s surfable, but nothing to write home about.
Wednesday the 5th morning has a little 3ft SSE swell with cross-off wind, but it’s ordinary. Things stay small and inconsistent through to Saturday the 8th. That afternoon some 5ft S swell shows up with a short period of 7 seconds and moderate energy (220), but it’s clean with cross-off wind. Still, the quality is ordinary.
Now, Sunday the 9th is where it starts to get interesting. A 6ft S swell rolls in the morning, with 11-second period, strong energy (1195), and a fresh cross-off breeze. It’s clean, but marginal. By Sunday afternoon, the swell jumps to 7ft from the south with a 14-second period – very strong energy (1838) – and moderate cross-off wind. This is promising but still considered marginal.
The standout window is Monday the 10th through Wednesday the 12th. Monday afternoon sees a 6ft S swell, 14-second period, very strong energy (1158), and offshore wind. That’s clean, well-shaped surf. Tuesday the 11th morning though, the swell hits 10ft from the south with 12-second period, massive energy (2405), and gentle offshore wind. This is too big for this break – it’s a real bomb, only for experts. Tuesday afternoon drops to 8ft, and Wednesday the 12th morning comes back to 6ft with offshore wind and clean conditions – that’s your best bet for a solid session without the size getting out of hand.
After that, through the second week, things taper off. Thursday the 14th morning has a glassy 5ft S swell, but it’s not a standout. The rest of the period is small, choppy, and not worth paddling out for.
The highlight is definitely Monday the 10th afternoon and Wednesday the 12th morning at Barrinha – solid south swell, good period, offshore or glassy wind, and clean waves. Tuesday the 11th morning is huge but only for the brave.
Rusty.

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.
