The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
First off, I gotta be straight with you—this is a lean run. We’re looking at a long stretch of small, pretty ordinary surf. The first wave of any note doesn’t show up until the morning of Friday, 25th July, and even then it’s more of a paddle than a proper session. The water temp is sitting at 66°, which is bang on average for this time of year, so no surprises there.
The best of the bunch, and the only real standout in the whole 16-day window, is the afternoon of Saturday, 1st August. The surf comes up to 4ft from the east, with a period of 8 seconds. The combined energy hits 214 (moderate wave energy), and we’ve got glassy conditions with a slight air. That’s clean, chest-to-shoulder-high fun for the experienced crew. For beginners, 4ft is a bit of a push, but if you’re comfortable, it’s the pick of the period.
Before that, from the 22nd of July right through to the 31st, it’s a real grind. Waves barely crack 3ft, the periods are short, and the wind is mostly cross or onshore. You’ll see a few morning windows with glassy conditions and a bit of energy around 100 to 150 (weak to moderate), but the quality is just not there. The morning of Saturday, 26th July, is a good example—3ft, glassy, 152 energy, but the wave comment says “very ordinary conditions.” It’s surfable, but nothing to get excited about.
After the 1st August stand-out, the surf drops back into the 3ft range through the 2nd to the 6th of August. The wind is mostly cross or light cross-on, and the energy levels are moderate (between 128 and 264). The morning of Wednesday, 5th August, is glassy with 3ft and 128 energy, but it’s just not a proper runner. The 6th of August morning looks glassy again with 3ft and 186 energy, but again, it’s ordinary.
So, to sum it up: if you’ve got a window, aim for the afternoon of Saturday, 1st August at Barra do Sul. It’s the only time the stars align for a clean, punchy session. The rest of the fortnight is a long, slow stretch of small waves and tricky winds. The break is fairly consistent, so it won’t stay this quiet forever, but for now, patience is the name of the game.
Rusty.
