The Lowdown
Alright, I’ve been staring at this 16-day window for our spot and, honestly, for the first week and a half, it’s a total bust. There’s a long, dry spell where the surf is just flat or blown out. But, like a sneaky set that catches you off guard, there’s a real good one waiting if you’re patient. The first real chance of anything decent doesn’t come until Tuesday afternoon, 1st of September, and even then, it’s a mixed bag.
Let’s break it down. Nothing for Saturday the 29th or Sunday the 30th. Saturday we’re looking at tiny 1ft waves from the SE, weak energy. Sunday afternoon shows a glimmer with a 4ft easterly swell, period of 8 seconds, and glassy wind. The energy is moderate, but it’s just "surfable but very ordinary." Not worth the drive.
Monday the 31st is a write-off. Onshore wind and rain, with messy, choppy conditions.
Now, here’s where it gets interesting. On Tuesday afternoon, 1st of September, the wind swings cross-off from the SSW at 22 mph, and it’s clear. The forecast shows a massive 12ft swell from the SSW with a period of 9 seconds. The combined energy is a huge 1651. That’s a lot of power. BUT, the file says it’s "predicted to be too big for this break." For an intermediate spot like Barrinha, 12ft is serious. It’s not a beginner wave, and for most, it’s going to be a beast. The wind is clean, though, so if you’re an expert and you know this break, it could be a session. But I’m not calling it a standout for everyone.
Wednesday the 2nd of September, the swell is still huge, 10ft in the morning, dropping to 8ft in the afternoon. Still too big for the average surfer. The energy is through the roof. The wind is light and cross-off, so it’s clean, but that size is intimidating.
After that, it drops back into mediocrity. Thursday the 3rd and Friday the 4th have cross-onshore winds and choppy waves. Saturday the 5th has a glassy morning with a tiny 3ft swell, but it’s from the NE, which isn’t our best direction.
Here’s the real standout. You have to wait for it, but it’s worth it. On Tuesday morning, 8th of September, the stars align. It’s a light rain, wind is light and cross-off from the S at 6 mph, so it’s glassy. The swell is 6ft from the S with a very long period of 12 seconds. That’s a proper groundswell. The combined energy is a strong 1004. This is the best on offer. The waves should have real shape, and the paddling out will be easier between sets. The guidance says Barrinha is "very consistent" and "fairly exposed" to the SE swell, but this swell is from the S, so it’s not a perfect match, but the size, period, and clean wind make it a winner. The crowds are listed as "sometimes," so you might have some company.
The rest of the second week is a mixed bag. Wednesday the 9th and Thursday the 10th have clean conditions but with "marginal" tide issues or cross-on winds. Friday the 11th has a glassy afternoon with a 3ft swell from the SSE at 13 seconds, which is good for a fun, small wave session. The last few days go back to small, weak, and windy.
So, bottom line: if you’re an expert, those big days early in September might be your jam. But for the rest of us, mark your calendar for Tuesday morning, 8th of September. That’s the one. The rest is a lot of waiting.

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.
