The Lowdown
Righto, Rusty here. Let's have a look at what's cookin' over at The Rock-Costa Azul.
Alright, so the next couple of weeks are looking a bit like a slow burn, not a constant cooker. For a solid reef break that's usually consistent, we've got a bit of a waiting game on our hands. The first few days are pretty average, so don't get too keen just yet. The real standout action is tucked away in the second half of the week and into the weekend starting August 15th.
Keep your eyes on Thursday morning, August 13th at The Rock. We're talking clean, glassy conditions with a light breeze from the SSW, making it dead still on the water. You'll be looking at a 3ft SSW groundswell with a 16-second period. Combined wave energy is sitting at a moderate 414. It's not massive, but that long period means it'll have some shape, and the glassy conditions will make it silky smooth. That's your sneaky good session for the more advanced crew.
But the real ripper, the one to circle on the calendar, is Saturday afternoon, August 15th. This is the true standout. The cross-offshore wind from the WSW will keep it clean as a whistle, and the swell bumps up to a solid 4ft from the SSW, with a 16-second period. The combined energy jumps right up to a strong 872. This has got proper push and will really wrap into the reef. This is where you want to be for the best waves of the whole outlook.
After that, it tails off into smaller, cleaner conditions for the following week, with a few scattered afternoons offering some knee-to-waist high groomed lines. The second week, around August 22nd and 23rd, offers some tiny, long-period swells in the 2ft range, but with strong offshore winds on the Sunday afternoon they could be fun on the right board.
A quick note on the water: it's much warmer than normal for this time of year, coming in at 87°F.
Rusty, signing out.
