The Lowdown
Alright, surfers, Rusty here. Let’s get into it. We’re looking at a run that starts a bit slow, builds to a couple of proper sessions, then backs off again before another pulse rolls in late in the window.
The first real call is Saturday, August 15th, at Praia da Baleia. The big fella shows up in the morning with a clean 7ft of south-southeast swell, 13-second period, and the wind is dead glass. The energy is strong, with a combined swell energy of 1398. It’s got some size, so this is for the experienced crew – beginners will find it a handful. Water temps are sitting at 71°F, which is a touch warmer than usual for this time of year, but no big deal.
That Saturday morning vibe looks like the standout of the first week. The point and beach setup will be handling that long-period swell, so expect some proper lines.
Sunday and Monday have waves, but the wind gets a bit messy on Sunday with a cross-shore breeze. Monday morning, August 17th, is another cracker though – glassy conditions again, 8ft from the east with a 9-second period, and strong energy at 1201. It’s powerful, clean, and again, one for the experienced surfers. That's your other standout – the mix of size and perfect conditions is hard to beat.
After that, things drop right off. From Tuesday the 18th through to the 22nd, we’re looking at a few days of small, weak surf. The energy drops way down, with combined swell energy values under 200, and waves getting down to 2ft or 2ft. It’s ordinary.
There’s a bit of a pulse on the 23rd, but the wind is onshore and it’s raining – not worth your time. The real action comes back on Monday, August 24th. It’s a long way out, so treat it as promising but not locked in, but there’s a big S swell at 8ft in the morning, and by the afternoon the wind goes glassy with a solid 8ft and 13-second period, and the energy is pumping at 1650. That looks like the best of the whole run. It will be sizeable, powerful, and clean – a proper session for the experienced.
After that, the swell eases but stays rideable through Tuesday the 25th and Wednesday the 26th, before fading out again into the end of the month. There will be some fun, cleaner waves on the 28th and 29th with small S swells, but nothing that’s going to blow you away. The 24th is the one to keep an eye on.
This is Rusty, signing off.
