The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day stretch for Praia das Macas is a tough one. The wind is a persistent problem, blowing cross-onshore day after day, and the swell quality just isn’t there. We’ve got a long, disappointing gap right from the start, with no real surf on offer until the tail end of the period.
The first solid chance doesn’t roll around until Tuesday, 19 August. The morning shows some promise, with a moderate wave energy reading of 704 (moderate energy) and a 7ft swell from the NNW. The period is 9 seconds, which is average, and the wind is a light breeze from the north at 6 mph, creating only light cross-onshore ripples. It’s marginal, but it’s the best we’ve got – a bit lumpy, but for an exposed beach break, you might find a few workable ones. The water temp is about average for this time of year.
Honestly, for the rest of the window, the wind is too strong and the swell is either too small or too messy. The setup is a consistent beach break, but with that persistent cross-onshore wind, it’s more of a kite surfer’s playground than a paddle surfer’s dream. Keep an eye on the forecasts, but don’t hold your breath.
Rusty.
