The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming our way. We’ve got a bit of a slow start, but there’s some real quality hiding in the back half of the forecast.
The first few days are a write-off for anything decent. Through Wednesday the 7th, we’re looking at tiny, weak swell with periods that are barely a pulse. The waves are rideable but totally ordinary, and the energy is laughably low. Honestly, it’s not worth paddling out for.
The real story starts to build on the weekend. Saturday the 8th sees a jump in size, but the wind is a total mess – strong cross-onshore stuff that’s gonna chop it up. The wave energy is ramping up though, so the potential is there if the wind plays nice.
The standout window is Sunday the 9th through Tuesday the 13th of August, with the absolute pick of the litter being Sunday morning at Praia do Porto.
Let’s talk about Sunday morning, the 9th. We’ve got a solid 7ft swell rolling in from the south, with a nice 11-second period. The energy is pumping, and the wind is offshore, blowing clean. This is premium stuff for experienced surfers. The water temp is about average for this time of year, so a spring suit will do. This is the session to circle on the calendar. By Sunday afternoon, the wind swings a bit cross-off, but the waves are still fun at 6ft.
Monday the 10th keeps the good vibes going. Clean conditions with a 5ft south swell, 11-12 second period, and light offshore breeze. The energy is good. Not as big as Sunday, but very rideable and a lot less push.
Tuesday the 11th the swell backs off a bit, dropping to 3ft, but the wind stays light and clean. It’s ordinary, but if you’re itching for a paddle, it’s doable.
Keep an eye on Wednesday the 13th afternoon. The wind goes glassy, and we get a 5ft SSE swell with a nice 11-second period. The energy is solid, and it’s going to be clean. That’s a sneaky-good afternoon session.
After that, the 14th and 15th have some ok windows, but the consistency drops and the wind gets tricky. There’s a pulse of 8ft swell on Tuesday the 18th, but it’s a bit junky with cross-onshore wind. That one is for the bigger boards and stronger paddlers only.
So, to wrap it up: Sunday the 9th morning is your best shot. Big south swell, offshore wind, and plenty of energy. Monday the 10th and Wednesday the 13th afternoon are great backup options. Don’t waste your energy on the first week. Be patient, and you’ll get rewarded.
Rusty.
