The Lowdown

Alright folks, Rusty here. Let’s look at what we’ve got for the next couple of weeks. It’s a pretty grim run for the most part, but there is a tiny window if you’re desperate.

We’re looking at Praia das Macas for the whole forecast. Right off the bat, the water temp is about average for this time of year, nothing unusual there. The break is a consistent, exposed beginner spot, and the optimum swell direction is from the NW. The problem is, for the first three days there’s just nothing worth paddling out for. The wind is a messy cross-onshore, and the swell is either tiny or short-period junk. From Friday 31st July through to Monday 3rd August, it’s a write-off.

Then, on Tuesday 4th August morning, things almost get interesting. The wind drops to glassy – that’s a huge plus – and we get a knee-high 1.0ft wave from the WNW with a period of 8 seconds. The combined energy is moderate (132). It’s surfable, but ordinary. The wind picks up again in the afternoon and turns onshore, so your window is the early shift. After that, it’s back to cross-onshore chop and small dribble for the rest of the week.

The real tease comes much later. On Sunday 9th August, we see a spike in swell. The morning brings a 6.2ft wave from the NW with a 10-second period. That’s a solid, powerful groundswell. The energy is strong (724). The wind is a light cross-onshore, so there’ll be some texture on the face. At 6.2ft, this is getting into the big range for a beginner spot, so it’s more for the experienced crew. The afternoon keeps the size but the wind swings onshore, killing the quality. The following Monday and Tuesday see even bigger swell – up to 6.6ft – but the wind is a mess: cross-onshore and choppy. That’s just lumpy, powerful junk, only for the experts, and honestly, it might be more fun for the kite surfers than paddle surfers.

The standout, if you can call it that, is Tuesday 4th August morning. The glassy conditions are a rare gift, but the swell is small. The bigger, more promising swell is Sunday 9th August morning, but it’s a long way out, so treat that with caution. It’s a shame the wind doesn’t line up with the size.

So, head down for a quick, glassy session on the 4th, or keep your fingers crossed for the 9th. Otherwise, it’s a pretty flat and choppy run.
