Barrinha Surf Forecast and Surf Report

Alright crew, Rusty here with the full rundown. Let’s see what the ocean has for us, starting right now.

The week starts with a bit of a wait for the proper waves. We’ve got a good, long-period groundswell building over the coming days, with a couple of real standout sessions for the experienced crew later on. Expect some longer lulls between sets with that long period energy.

Monday morning (7th September) isn’t the one to rush for. Even with clear skies and a light offshore breeze, the 6ft south swell has only moderate energy (551). The pulse just isn’t organised enough. By afternoon, a light cross-onshore breeze from the ESE messes with the face, making it a marginal call.

Tuesday (8th September) we see the surf drop to 4ft and the wind turns onshore from the north. Choppy conditions make it a write-off.

Wednesday morning (9th September) is where we get our first taste. The wind dies completely – glassy conditions. Swell holds at a modest 4ft from the south with a clean face. Energy is still moderate (315). It’s a fun, small wave for a morning paddle when you just need to get wet. The afternoon sees the period stretch to 12 seconds but a light cross-shore from the SE brings in a little ripple.

Thursday afternoon (10th September) is a sneaky good one. A clean 4ft south swell, but with a 14-second period and a nice cross-off breeze from the NNW. Wave energy jumps to a solid moderate (510). The sets have a bit more push and the lines should be peeling nicely. That’s a solid session.

Friday (11th September) the energy fades. We’re down to 2ft and onshore winds. Swell drops away quickly. A few flat days follow, with Saturday morning (12th September) seeing the bottom fall out at only 1ft and 29 combined energy. Not worth the drive.

Then the ocean wakes up. Saturday afternoon (12th September) – hold onto your board. A powerful 12ft south swell rolls in with a 10-second period. Wave energy is a massive 2076. For a spot like Barrinha, that’s way too much juice. This is expert territory only; beginners stay well clear. The wind is cross-off and clean, but the size is intimidating.

Sunday (13th September) keeps the big energy going. 10ft from the SSE, 12-second period, and combined energy of 2439 in the morning. The wind stays favorable, cross-off in the AM, but it’s still a heavy, powerful wave. Again, for experienced surfers who know the peak.

Monday (14th September) the swell drops a touch but onshore winds from the NE chop it all up. 8ft on a choppy face is not inviting.

Tuesday morning (15th September) things settle a bit. A clean 5ft swell from the SE with a 12-second period and cross-off SSW wind. Energy still moderate (582). It’s more manageable, but the tide might be tricky. The afternoon gets a little bumpy.

Now, the absolute standouts of the entire outlook come mid-week.

Wednesday morning (16th September) is glassy – dead calm with 6ft of south swell. But the period is short at only 8 seconds, so it will be a bit weaker and more crumbly. The real gold is Thursday and Friday (17th & 18th September) . Thursday morning brings a clean, 8ft south groundswell with a 14-second period and cross-off wind. Combined energy is a strong 2202. The lines will be long, clean, and powerful. This is legitimately excellent surf, but because of the size, it’s for experienced surfers only. Friday morning follows it up with an 8ft, 15-second period south swell and cross-off wind, pushing energy to 2892. Friday afternoon the wind goes glassy with 8ft on the face. This whole window is the pick of the next two weeks.

The weekend after that (19th & 20th September) the swell backs off and the wind turns onshore, leaving us with small, weak leftovers. By Monday (21st) and Tuesday (22nd September) , we’re down to ankle-biters with almost no energy.

The bottom line: The absolute highlight is the Thursday 17th and Friday 18th September window. Clean, powerful south groundswell, cross-off to glassy winds, and solid moderate-to-strong wave energy. This is a call for experienced surfers to clear the schedule. Everything else in the first week is a build-up, and the second week fades into a flat spell.

Stay safe out there.

Rusty.
