The Lowdown
Alright, Rusty here again. Let’s talk about what’s coming up at Barrinha. We gotta be patient for the good stuff, but there’s some real promise later on.
The overall pattern kicks off pretty flat and messy. From Saturday the 12th right through to about the 20th, the swell is small, the wind is mostly side-off or side-onshore, and the conditions are just poor. You're looking at knee-to-waist high waves at best. That’s a solid 8-day stretch of just not worth paddling out.
The first real window pops up on Monday the 14th of September. There's a clean, light offshore wind in the morning with a 4ft swell out of the south. It’s not huge, but the conditions are right for a fun little session. Don't get too excited yet though.
We hit another dry spell after that Monday window until Tuesday the 22nd of September. That morning, the energy spikes hard with an 8ft south swell. That’s a lot of power. The problem is the wind is side-off and it’s flagged as marginal, so it might be a bit rough and only for the experienced crew.
The real standout, the one you block out time for, is Friday the 25th of September. This is it. Early morning, it’s glassy, dead calm. The swell is a clean 6ft out of the SSE with a long 12-second period. That’s proper groundswell. The conditions are forecast to be very good. This is your day. For a beach break, that long period might make it a little straight, but the quality and clean glass make it the clear winner of the whole 16-day outlook.
After Friday, the swell drops but stays ridable through Saturday, though the wind gets a bit tricky.
The water temp is about average for this time of year.
So, bottom line: sit through a long, flat first week, get a small taste on Monday the 14th, maybe look at the big power on Tuesday the 22nd, but hold out for that glassy Friday morning on the 25th.
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.
