The Lowdown
Alright, let’s talk surf. Rusty here.
It starts off with some size then goes flat and messy before two decent windows pop up later on. For Barrinha, you’re gonna need a bit of patience.
Monday morning the 24th brings a solid 8ft south groundswell with a 14-second period, and the energy is strong (3029). Early glassy conditions with light southwest wind – clean waves for those who can handle it. That’s expert territory with that size. Water temp is normal for this time of year, nothing wild.
After that, the wind turns cross-onshore and picks up. Tuesday the 25th still has 6ft swell, but the northerly wind messes it up. Wednesday the 26th pushes back up to 8ft and even 8ft with strong energy (3300), but again, cross-onshore chop kills the quality. Thursday the 27th through Sunday the 30th is tiny and poor. Days of flat, windblown nothing.
Looking into the second week, Tuesday morning September 1st is worth a look: 7ft south swell with 8-second period, glassy offshore southwest wind. Clean, moderate energy (608). Good for intermediates.
The standout is Wednesday morning September 2nd. Barrinha gets 8ft SSW swell with calm, glassy conditions. Period is 9 seconds, energy is strong (1366). This is excellent for experienced surfers. Crowds are possible here, so get in early if you want a clean one.
After that, swell drops fast. Small and onshore through to the end.
So: wait out the early slop, then hit Tuesday the 1st for clean fun, and Wednesday the 2nd is the real standout. That Wednesday is the one to circle.
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.
