The Lowdown
Alright, let’s break down what’s happening for Praia das Macas over the next couple of weeks.
I’m gonna level with you – this stretch is a real bummer for paddle surfing. The whole 16-day window is mostly a no-go. The only little hint of something worthwhile is way at the end.
It starts Tuesday, July 21, with a tiny 3ft swell out of the NNW, period a short 8 seconds, and a combined energy of 149 (moderate). Wind is offshore but it’s just not enough to make anything happen – the call is “poor surf conditions” from the start. Water’s about 69°, right on average for this time of year.
Wednesday and Thursday are even smaller – down to 2ft and 2ft with periods dropping to 6-7 seconds. The wind turns cross-onshore on Thursday, roughing things up. Friday is more of the same – light onshore and weak.
Saturday the 25th sees a pulse – 5ft to 6ft from the NW, but the period is still just 7 seconds, and there’s a fresh cross-onshore wind making it lumpy. The combined energy hits 336 (moderate), but it’s messy.
Sunday the 26th is the biggest push of the whole run – 7ft from the NNW, period 8 seconds, and a combined energy of 650 (strong). But the wind is screaming from the north at 25 mph, straight cross-shore, creating a mess of cross-chop. At that size with those winds, this is more of a kite-surfing show than a surfing one.
The next week – from Monday the 27th all the way through to Tuesday August 4th – is just a slog of small, onshore, or cross-onshore junk. Every single entry says “poor surf conditions”. The swell hangs between 3ft and 5ft, but the period stays short, and the winds keep it choppy.
Now, August 5, Wednesday morning – that’s the one and only glimmer. A light cross-offshore breeze from the SSE at just 3 mph – actually clean conditions for a change – with a 4ft swell from the NNW at 7 seconds, and a combined energy of 139 (moderate). The call is “surfable waves but very ordinary conditions”. For this stretch, that’s about as good as it gets. It’s beginner-friendly size, but the wind will clean it up nice. Crowds are possible at Praia das Macas. If you’re desperate for a session, that’s your only shot – the rest of the period is a write-off for paddle surfing. But hey, it never stays flat forever around here, and forecasts can always shift.
