The Lowdown
G’day, Rusty here. It’s been a bit quiet, but things are about to fire up at one spot.
Alright, we’ve got a proper run of surf kicking off at Barrinha. The water’s sitting at a pretty average-for-the-time-of-year 67°, nothing weird there. The first real session to mark on the calendar comes in on Friday morning, August 21st. You’ll see a clean 5ft swell from the SSW with light offshore breezes – that’s a green light for some fun, tidy waves.
Now, keep an eye on Saturday afternoon, August 22nd. The swell jumps to 8ft from the S, with clean conditions and a gentle cross-offshore wind. Wave energy is pumping at 1604 (moderate to strong), and it’s shaping up for a ripper session. This one’s a standout for the experienced crew – not a beginner’s wave. The swell period is 9 seconds, so it won’t be a lazy, long-wait groundswell, but it’ll have plenty of push.
Sunday morning, August 23rd is also a treat: 6ft from the S, glassy light airs, and 875 energy. Clean lines and no wind hassle – a solid choice.
But if you want the true standout of the whole forecast, that’s Monday morning, August 24th. The swell hits 10ft from the S with a very long period of 16 seconds – that’s proper groundswell, deep ocean energy. Energy reading is a massive 4132 (very strong). Here’s the thing: with that long period and size, it’s gonna be too big and powerful for many beach breaks, but at a spot like Barrinha it could be a beast for the experts only. The wind is just a light cross-offshore, so the surface will be clean. This is for serious experienced surfers only – don’t even think about taking a foamie out there.
There’s another late runner on Tuesday morning, August 25th: 7ft from the S, glassy conditions, and 1376 energy. Another excellent window, but the Monday morning is the one to aim for.
After that, it fades into a long flat spell. From Thursday afternoon the 27th right through to the end of the month, it’s small and choppy, with nothing worth paddling for. Another pulse rolls in on Wednesday morning, September 2nd, with 10ft from the SSW and 2975 energy, but the wind is onshore and messy – a miss for quality.
So, bottom line: Monday morning the 24th is the big standout, but it’s for experienced locals only. Saturday the 22nd and Sunday the 23rd are your best bets for a clean, fun session without the monster swell. The rest is a waiting game.
Stay stoked,
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.
