The Lowdown
Alright, let’s have a look at what’s on offer for the next couple of weeks.
It’s gonna be a lean stretch for a while, I’m not gonna sugarcoat it. The first solid week is basically a write-off for any real surf. From Monday 27 July right through to the end of the month, and into the first few days of August, the waves are tiny, weak, and messy. The combined energy barely gets into double digits – you’re looking at figures like 94 and 52, which is flatter than a millpond. The only real highlight in that first week is the water temp sitting at 65°F, which is bang on average for this time of year, so no complaints there.
We’ve got a gap of several days with nothing worth paddling out for. Then, around Tuesday 4 August, things start to flicker. Early that morning, there’s a small pulse of 2ft from the SSE with a long 12-second period – that’s groundswell energy. The combined energy jumps to 150 (moderate), and the wind is glassy. That’s a rare window. The swell direction from the SSE isn’t perfect for the spot’s optimum ENE, but with those conditions and no wind, it’s a sneaky good session for the early bird.
The standout, and I mean the only real standout in the whole 16-day window, comes on Friday 7 August. That morning, the swell is 4ft from the SE, period 8 seconds, with a clean offshore breeze from the south. The combined energy sits at 284 (moderate). The afternoon glass off with 4ft from the SE and a 9-second period, combined energy 275, and glassy conditions – that’s a beautiful window. For a beginner-friendly spot like Barra da Lagoa, that’s about as good as it gets in this run. The swell is under 5ft, so it’s perfect for beginners and intermediates alike. The wind is clean, the waves are fun-sized. Just be aware that crowds are often around here, so get in early.
After that, it fades again. The weekend of 8-9 August has some lumpy, choppy wind, and by Monday 10 August, the south wind is howling at 19 mph with tiny waves. It’s a bit of a kite-surf setup by then, not great for a paddle.
So, to wrap it up: if you’re keen, circle Friday 7 August. That’s your best bet. The rest of the window is mostly small, weak, or windblown. Don’t hold your breath for the second week – it’s looking pretty quiet.
