The Lowdown
Alright, Rusty here, checkin' in with a look at what’s ahead. This is a quiet run for the most part, so you'll need some patience. The first real window doesn't open up until the weekend after next.
We’ve got a long flat spell on our hands. From now through Friday the 22nd, it’s mostly tiny dribble or straight up poor conditions with those northerly breezes messin' up the surface. It’s a frustrating stretch.
Things start to wake up on Saturday the 22nd. Barrinha gets a pulse of southerly swell, pushin' 6ft with a 9-second period. The wind will be clean, coming offshore from the SW, so the lines should be tidy. The energy is moderate (554), and it's a consistent spot, so there'll be waves to go around. That morning is your best bet, as the afternoon gets a bit stronger but windier.
Sunday the 23rd is a solid pick too. Swell holds around 7ft from the south, period stretches to 11 seconds, and the wind stays clean and light from the SSW. The energy bumps up strong (1068). Sets will have more push, and paddling out between them will be a bit easier with that longer period.
Now, if you're experienced and want the standout, mark your calendar for Monday the 24th. We’re lookin' at a proper groundswell: 8ft from the south with a very long 14-second period. The energy is through the roof (2662), and the morning is glassy as a mirror with no wind. This is big, powerful, and clean – but at 8ft, it's for experts only. The longer period will make it wall up nicely, but at a beach break like this, it could be a bit straight. The crowds might show up.
After that peak, it fades quickly. Tuesday the 25th gets messy with a stiff northerly onshore wind chopping up the 6ft swell. The rest of the week into September looks small and mostly blown out or weak.
So, the call: If you’re a confident surfer, be on it for the Monday the 24th morning session – that’s the real gem. Otherwise, the Saturday 22nd or Sunday 23rd mornings offer clean, fun waves for the intermediate crew.
Rusty, signing off.

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.
