The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the next 16 days around here.
First up, we’ve got a stretch of pretty ordinary conditions on the way. The opening days are a write-off, with strong cross-onshore winds and clean waves nowhere to be found. Wednesday 26th and Thursday 27th are both no-go, with messy, lumpy surf and wind that just won’t let up. By Friday 28th, the swell drops away completely, so you’re better off leaving the boards in the shed for a few days.
There’s a distinct gap in the action from the 26th right through to the end of the month. Small, clean surf does appear Sunday 30th afternoon, but it’s weak and only just surfable – a 3ft SSE swell with glassy wind, but it’s not going to get the heart racing.
Then we roll into September. The first two days remain uninspiring, with cross-offshore winds but swell that’s short period and below par. Wednesday 2nd is similar.
Now, here’s a standout worth circling. Thursday 3rd September at Barrinha looks like the pick of the lot. We’re looking at a 6ft swell from the south, with a 10-second period giving it some shape. The wind is light and cross-offshore, leaving the surface clean. The combined wave energy hits 713 (moderate), and it’s marked as very consistent. The only downside? Crowds are sometimes an issue here, so get there early if you can. The morning session is the one to aim for.
Friday 4th and the weekend after that fade back into small, ordinary conditions, with light winds but not enough push to get excited about.
The real wildcard comes up on Thursday 10th September. There’s an 8ft swell from the SE, with a 10-second period, and the combined energy jumps to 1296 (strong). That’s big enough to be expert-only territory, and unfortunately the wind is cross-on, so it’s going to be a bit of a battle. If you’re a strong paddler and you know the break, it could be a session, but it’s not the cleanest setup.
Overall, the best on offer is definitely Thursday 3rd September morning at Barrinha. Don’t sleep on that one.
Water temperature is sitting around 65°F in the first few days, which is about normal for this time of year – no surprises there.
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.
