The Lowdown
Alright, grab your board, let’s talk about what’s cookin’ at my local stretch. We’ve got one spot on the radar: Barrinha. It’s a fairly exposed, intermediate-level sandbar that can be very consistent, but for the next little while, it’s gonna be a real mixed bag—some clean moments, but plenty of frustrating, choppy days too.
Right now, the start is pretty grim. We’re lookin' at tiny, messy surf with onshore wind messing things up. The first session that’s even worth paddling out for isn't until Monday morning, July 27th. It’s glassy, with clean conditions and a weak 2ft south swell. The wave energy is still pretty low (179), so expect small, weak waves—but at least it’ll be smooth.
Tuesday morning, July 28th, looks better on paper—clean and glassy, with a short-period 5ft NNE swell rolling in. That’s a bump in size, but the period is short (6 seconds), so it won’t have much push. The water temps are about average for this time of year, nothing weird goin' on there.
The real standout window—the one you’ve been waitin' for—arrives on Wednesday, August 5th. Both the morning and afternoon are looking crisp, with clean cross-offshore winds. Swell height hits 5ft to 6ft from the east, period is short at 8 seconds, so it’ll be a little crumbly, but the energy is solid (362 and 435). This is the best on offer for the whole 16-day span. It’s not huge, but a fun-sized day for intermediates. Crowds are *sometimes* a factor here, so you might have to share.
After that, it fades again. A few clean days pop up, like Monday, August 10th with an offshore breeze and 2ft south swell (202 energy) but it’s just ordinary—nothing to write home about.
So bottom line: the first week is mostly a write-off with small, bumpy surf. The standout date to circle is *Wednesday, August 5th*. Beyond that, the second week looks quieter and less reliable. The long-range promise is there, but nothin’ locked in.

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.
