The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for our local stretch.

Right off the bat, we’ve got a bit of a slow start. The surf is small and pretty ordinary for the first few days, so don't rush out. Things start to get interesting from Saturday the 8th.

The real standout in this whole 16-day window is shaping up for Saturday, August 18th. The morning at Praia da Baleia is looking like a proper session. We’re talking a solid 8ft swell from the south with a moderate 11-second period, pushing a heap of energy. The wind is forecast to be glassy, so it’s going to be dead clean. The combination of size and offshore conditions? That’s a serious proposition for the experienced crew. This is the one to circle on the calendar. By the afternoon, it’s still pumping at 10ft, but the wind swings cross-off, so it’ll still be clean, but that size is pushing into expert-only territory.

Before that, we’ve got a few other windows worth a paddle. Saturday morning the 8th sees a modest 4ft south swell with glassy conditions and moderate energy. It’s not the biggest, but it’ll be clean and fun.

Then Sunday the 9th offers a slightly bigger 5ft south swell with a longer 14-second period, bringing good energy. The wind is cross-off, so the waves will be clean. The longer period between sets might make the paddle out a little easier, but a south swell with that kind of period can be a bit straight at a beach setup, so pick your spot.

The 13th of August also looks clean. Thursday morning has 5ft from the south with a cross-off breeze, and the afternoon drops to 5ft with glassy conditions. Nice, clean, manageable surf.

And don’t sleep on the 14th of August. Friday morning has a 5ft south swell with a long 14-second period and glassy wind. The energy is high, and the conditions are excellent. That’s a morning to get out of bed for.

The water temperature is about average for this time of year, so no need for a thick wetsuit unless you get cold easily. Crowds at Praia da Baleia can pop up sometimes, but with the conditions on offer, especially on those standout days, it’ll be worth the company.

The end of the window on the 21st of August shows a 7ft swell from the ESE with a short 8-second period and clean cross-off wind. The energy is solid, but the short period can make for a bit of a lumpy, less defined wave. Still, it’s a clean option.

Overall, there’s a slow start, but the second week has some proper gems. Keep your eyes on the 14th and definitely the 18th.

Rusty.
