Alright folks, Rusty here. Let’s have a look at what’s in store for Praia das Macas over the next couple of weeks.
There’s some swell on the horizon, but I gotta be straight with you – for the entire 16-day window, the conditions are looking pretty ordinary. The wind is almost always cross-on, and the wave quality is rated as poor. There’s no standout session that’s going to get you frothing, so we’re in for a bit of a flat spell with onshore chop.
From Thursday 9 July through to Wednesday 15 July, the swell is tiny, mostly around 1 ft to 3 ft, and the period is short – between 6 and 11 seconds, so it’s weak, crumbly, and lacking any punch. The best of this poor bunch is perhaps Saturday 11 July afternoon, when we get a light onshore wind from the WNW and a 2 ft swell with a period of 11 seconds, giving a combined energy of 133 (moderate). The water temp is about average for the time of year, so no worries there, but it’s still poor surf.
The weekend of 18-19 July brings a bit more size – we’re looking at 3 ft to 5 ft from the NW on Saturday 18 and Sunday 19, with periods around 9-10 seconds, and energy picking up to 210 (moderate) and 267 (moderate). But again, it’s cross-on wind from the NNW at 12-15 mph, so it’ll be choppy and messy. Still not worth rushing out for.
The second week is more of the same: from Monday 20 July through to Friday 24 July, we see continued cross-on winds (often fresh breeze at 15-25 mph), with swell heights between 2 ft and 5 ft, but the period drops to 4-8 seconds – that’s windswell, not groundswell. The energy is moderate (values like 177, 152, 222), but the wind is just too strong and onshore to make it clean. The swell direction is mostly NW or NNW, which is a decent match for the optimum direction (NW) for this break, but it doesn’t matter when the wind is wrecking it.
Honestly, there’s no good surf here in this 16-day window. It’s a consistent break, but the conditions are just not cooperating. Kite surfers might find it more interesting with those strong cross-on winds, especially from 21 July onwards when the wind is over 18-25 mph, but for a paddle surfer, it’s a long wait. Forecasts can change, but right now, this is a write-off.
Rusty.
