The Lowdown
Alright folks, Rusty here. Let’s get stuck into the local outlook for Barra da Lagoa over the next couple of weeks.
Alright, the honest truth is the next week and a half is looking pretty flat and grim. There’s a big gap here with nothing really worth paddling out for. The first real swell window doesn’t open up until Friday, August 7th, so that’s a solid 10-day stretch of small, weak, and generally poor conditions. Don’t get your hopes up for the next week – it’s mostly tiny dribble and onshore junk.
The one glimmer on the horizon, and I mean the *only* one, is the morning of Friday, August 7th. That’s your standout. Barra da Lagoa should see a pulse of 6 ft swell coming from the SSE with a decent 10-second period. The combined energy is a solid 501, which is proper moderate wave energy. The wind is predicted to be cross-off from the N at 9 mph, which will keep the surface reasonably clean. It’s a bit of a wait, but that’s your best bet for a surfable wave in this whole forecast period. The afternoon drops off a bit, so make it a dawn patrol mission.
Water temp is sitting at 63°, which is a bit colder than normal for this time of year, so you’ll want a good wetsuit.
Nothing else comes close. The rest of the days are tiny, weak, or blown out. It’s one of those quiet spells we get here. Keep an eye on it, but don’t rearrange your life for it.
Rusty.

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.
