The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for Barra da Lagoa over the next couple of weeks.

Right off the bat, I gotta be straight with you – the surf is pretty much dead for a solid stretch after today. We’re looking at a big gap with nothing worth paddling out for until Thursday the 12th of August rolls around, and even then it’s just marginal. The real wait is on.

Thursday 13th August morning is where it finally starts to look interesting. We’ve got a clean, 6ft swell rolling in from the SSE with a long 14 second period – that’s proper groundswell energy. The wind is a light cross-offshore from the south, so it’ll be clean. The combined energy is strong at 1241, so there’s some decent power behind it. Keep in mind, with that period the waves might wall up a bit on the beach, but if you pick your peak, it’ll be worth it. This is the standout window for the first week.

The Thursday afternoon holds up okay, but the morning is the pick.

Then we drift into a few days of smaller, less organised stuff. Friday the 14th drops to 6ft with a shorter 13 second period, and the wind is a bit of a mess – cross-shore and onshore at times. The energy drops to 1077, still moderate but not as punchy. By Saturday and Sunday the swell fades to around 4ft to 4ft with a short 8 second period – weak energy in the 160-280 range. It’s surfable but ordinary.

From Monday the 17th right through until late in the month, we hit another dry spell. There’s barely a ripple – flat and poor conditions dominate. You’ll see some glassy mornings on the 22nd and 23rd, but with tiny swell – 2ft to 2ft – there’s just nothing to ride.

Now hold on, because the real firecracker is hiding at the end of the outlook. Tuesday 25th August afternoon brings a 8ft SSE swell with a 14 second period. The combined energy is a massive 2056 – that’s strong, powerful stuff. The wind is a light cross-offshore from the southwest, so it’ll be clean. This is expert territory – over 8ft is for pros, and at 8ft it’s solid, definitely not for beginners. This is the standout of the whole forecast, but it’s deep in the second week, so keep an eye on it – long-range calls can shift.

Wednesday 26th August morning still looks good with a clean 6ft swell and 1053 energy, a nice follow-up session.

So, if you’re patient, the best windows are Thursday 13th morning and that big Tuesday 25th afternoon. The rest of the time, honestly, leave the board in the car and wait for the forecasts to change. It tends not to stay this quiet for long around here.

Stay wet,
Rusty
