The Lowdown
Alright, let’s break it down in feet and miles per hour for those who think that way.
Rusty here. Honestly, the outlook is a tough one. We’ve got a long stretch of flatness and poor conditions for nearly two weeks. The only real opportunity worth paddling for comes right at the end of the second week.
The spot we’re looking at is Barra da Lagoa. It’s a beginner-friendly break, fairly consistent, and gets some exposure. The water temp is normal for this time of year, nothing unusual.
Here’s the play-by-play:
Sunday, 2 August through Tuesday, 4 August – bone dry. No swell, poor winds. Don’t bother.
Wednesday, 5 August – still mostly flat. On the afternoon we see a tiny 0.8ft swell from SSE, period 10 seconds, with glassy wind. Combined energy hits 109 – just moderate. It’s surfable but very ordinary.
Thursday, 6 August to Tuesday, 11 August – a total dead zone. No swell.
Wednesday, 12 August – a pathetic 0.7ft from NNE with a 3-second period. Combined energy of 2. Skip it.
Thursday, 13 August – nothing.
Friday, 14 August (morning) – glassy, but only 0.2ft from SE with a 13-second period. Not enough. Friday afternoon we get our first real pulse: 5ft from SSE at 11 seconds. Combined energy jumps to 558 – strong. But the wind is cross-on from SE at 10 mph, so it’ll be a little messy.
Saturday, 15 August (morning) – still 5ft from SSE, period 10 seconds, combined energy 490. Wind is light and cross-shore, so maybe a bit cleaner. Afternoon the wind picks up to 20 mph cross-on, chopping it up.
Sunday, 16 August (morning) – this is your window. Swell drops to 4ft from SSE, period 10 seconds, combined energy 364. The wind shifts to a light cross-off from WNW, nearly glassy. It’s being called “expect good surf conditions.” This is the best of the whole 16 days. Clean waves, decent shape, and a fun size for a beginner-friendly break.
Monday, 17 August – swell fades to 2ft, and the cross-shore wind messes it up again.
So, one solid morning on Sunday, 16 August is the takeaway. The rest is a lot of waiting. If you’re into kiting, the bigger choppy afternoons might work, but for a regular surfer, it’s a long wait for one good session.
Rusty.

A general guide to surfing at Barra da Lagoa can be found by selecting the local surf guide option on the grey menu. Our Barra da Lagoa 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.

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 Barra da Lagoa 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.
