The Lowdown
Right then, let's have a look at what's on the cards for Barrinha.
The forecast kicks off on Friday the 4th with a bit of a dud, really. We’re looking at small, weak energy (106) from the southeast – only 2.3ft on a short 10-second period. The wind is cross-off, but it's a moderate breeze, so it's not all that clean. Honestly, it’s a bit of a write-off for a proper session.
Saturday the 5th doesn’t offer much more. The swell bumps up a touch to 3ft from the south, but the period is still a short 9 seconds and the energy is moderate (171). The wind lightens up to a cross-off, which is something, but the waves are just ordinary. The forecast shows a bit more size in the afternoon, 3.6ft, but it's nothing to get excited about.
Now, Sunday the 6th is where things start to get interesting. The morning shows a solid 7.5ft of south swell, a moderate 8-second period, and a combined energy of 679 – that’s proper moderate energy! And the wind? Good offshore from the southwest. That’s going to set up some clean, punchy lines. This is the first real standout, but at 7.5ft, it's getting into expert-only territory. Sunday afternoon jumps up to 8.2ft with even more energy (1401) but the wind swings cross-off, so it won't be as clean.
Monday the 7th is a beauty of a morning. Glassy conditions with a light offshore from the southwest and a clean 5.6ft south swell (540 energy, 10-second period). This is the pick of the first week for intermediate surfers, offering clean, well-shaped waves. The afternoon goes onshore and turns to junk, so hit it early.
Tuesday the 8th is a write-off with onshore winds and choppy conditions, and the swell drops back. Wednesday the 9th and Thursday the 10th offer small glassy windows but with tiny, weak waves (2ft and 1.6ft) – barely enough to push you along. The water temp is 65.7°, which is basically average for this time of year.
After that, we hit a proper flat spell from Thursday afternoon through to the end of the week. Size drops to 0.7ft and the energy plummets to 14 on the combined scale. It’s a full-on lull for about 3 to 4 days.
But hold onto your board, because the second week has some real potential. Sunday the 13th sees a fresh pulse of 8.2ft south swell (energy up to 1273) with cross-off winds, but the forecast teases marginal conditions. The real gold is Monday the 14th and Tuesday the 15th. Monday morning brings a solid 7.5ft south swell on a long 13-second period with a fantastic offshore wind. The combined energy is a whopping 1846 – that’s strong wave energy. This is an excellent call for experienced surfers, and the long period means it'll be powerful and deep. Tuesday the 15th settles slightly to 6.2ft on a 13-second period from the SSE, but with a gentle offshore, it’s going to be beautiful, clean, and lined up. Another highlight.
From Wednesday the 16th onward, the swell fades and the winds become less reliable, with onshores creeping back in by Friday the 18th. The long-range standouts on the 14th and 15th are promising but, as always, a little less certain this far out. Crowds at Barrinha are "sometimes" a factor, so on these better days, you might find it a bit busy.

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.
