The Lowdown
Alright, Rusty here, let’s chew the fat on this forecast.
First things first, it’s a quiet opening. The first week or so at Barrinha is mostly flat or messy, nothing to get excited about. We’re looking at a big gap with no real surf from about Saturday the 17th onwards, stretching through the week. The first proper action doesn’t pop up until Sunday the 23rd of August.
The red-letter window is Sunday the 23rd and Monday the 24th of August. On Sunday, there’s a hefty South swell hitting 10 feet, with a 12-second period. That’s a lot of juice – the energy reading is 3413, which is strong. But honestly, that’s probably too big for this spot. Only the real chargers might want to look at it, and even then, it’s sketchy. The wind is light offshore from the SSW, so it’ll be clean, but that size is a beast.
The smart play is Monday the 24th of August. The swell drops to a more reasonable 6 feet from the South, still with an 11-second period. The wind goes light offshore from the WSW, setting up “very good surf conditions.” The energy is moderate at 698, but with that wind, the waves will have some proper shape and be clean. That’s your best window.
There’s a little blip on the 30th with a smaller, shorter period swell (5 feet, 7 seconds) and clean cross-offshore wind, which could be fun on a smaller board, but it’s nothing compared to that main weekend.
So, keep the board waxed for Monday the 24th. That’s the one to aim for.

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.
