The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a quiet start. The first few days are pretty much a write-off for any decent waves. We’ve got some small bumps showing up, but the wind is messy and the quality just isn’t there. You’ll be staring at a flat, choppy ocean for the first week, honestly. From the 14th through to the 23rd of August, it’s mostly all poor surf conditions and zilch for energy. A few little pulses on the 16th and 22nd, but they’re tiny and the wind is all wrong. Save your energy.
Now, things start to get a little more interesting as we head into the final week of August. The standout window looks like it’s going to be the 24th and 25th of August. On Monday the 24th, we’ve got a bit of a pulse arriving. The morning is still clean but small, then by Monday afternoon, Barra da Lagoa sees a 4ft swell from the SSE, period around 8 seconds. It’s not a monster, but it’s surfable. The real gem looks like Tuesday the 25th. The morning brings a 4ft swell from the SSE and the wind is glassy – dead calm, offshore from the SW. That is a rare treat for this spot. The water temp is sitting at 65°F, pretty much bang on average for this time of year, so no surprises there. The combined energy on Tuesday morning is moderate at 211, which is a solid step up from the rest of the week. The afternoon stays glassy with a 4ft swell from the SE. It’s not huge, but it’ll be clean and fun. This is the best we’ve got, so if you’re keen, that’s the day to paddle out.
The 27th and 28th offer a few more glassy windows, but the swell is smaller and the energy is lower. Still, if you’re jonesing for a wave, the Thursday morning (27th) with glassy conditions and 2ft from the SSE might be worth a look for a longboard or a foiler. The crowd profile at Barra da Lagoa says it gets “often” busy, so during the decent spells, expect company.
Overall, it’s a slow start, but the second week picks up a little. The real highlight is that Tuesday the 25th. Mark it down.
Rusty.
