The Lowdown

Alright, let’s get into it. I’m lookin’ at the full 16-day window here, and I gotta be straight with you – it’s a tough run. The only break on the radar is Praia das Macas. And honestly, the whole stretch is a bit of a write-off for decent waves. Every single session in the forecast is marked as poor surf conditions. There’s a big gap of nothing but choppy, cross-onshore junk from start to finish. No standouts, no gems. Just a long, flat, windy grind.

We kick off on Wednesday, 29 July. Morning sees some clouds with a N wind at 9 mph, cross-on, bumping into a weak 3 ft swell from the NNW. The period is a short 9 seconds, and the combined energy is only 161 – weak stuff. The water’s at 67.6°, which is pretty normal for this time of year, about average. The afternoon turns clear but the wind jumps to 16 mph from the NNW, still cross-on, still choppy. Swell drops a touch energy-wise to 141. Nothing to get excited about.

Thursday the 30th is more of the same. Morning swell is a tiny 1.6 ft from the WNW, period 10 seconds, but the wind is 12 mph from the N, cross-on, and the energy is a paltry 88. Afternoon bumps up to 2.6 ft from the NNW, but the wind is 16 mph, choppy, energy 121.

Friday the 31st isn’t much better. Morning has 3 ft from the NNW, but the period is a shocking 5 seconds – that’s pure wind chop. Energy is 58. The afternoon swell is 3.3 ft, same short period, but the wind is up to 19 mph from the N, making it lumpy and fresh.

Saturday the 1st of August: morning is a weird one – a cross-shore wind from the N at 12 mph, which is a bit different, but the swell is only 2.3 ft from the W, period 9 seconds, energy 156. Still not clean. Afternoon turns back to a cross-on 16 mph NNW wind, and a 3.9 ft swell from the NNW, period 6 seconds, energy 176. Choppy.

Sunday the 2nd: morning 2 ft from the W, period 9 seconds, but the wind is 9 mph N, cross-on, energy 114. Afternoon: 3.3 ft from the NNW, period 7 seconds, wind 16 mph NNW, choppy, energy 167.

Monday the 3rd: morning has a rare offshore wind from the WNW at only 6 mph, but the swell is tiny at 2 ft from the W, period 9 seconds, energy just 75. The wind description is “unknown” – which is odd. It’s the closest we get to clean, but there’s barely any wave. Afternoon the wind swings back to a cross-on 12 mph from the W, choppy.

Tuesday the 4th: morning sees a light cross-on from the NW at 6 mph, swell 3.3 ft from the WNW, period 8 seconds, energy 153. It’s got small wind ripples, not clean. Afternoon: wind picks up to 16 mph NNW, cross-on, choppy, energy 138.

From Wednesday the 5th through to the end of the first week, it’s a relentless beatdown of cross-onshore winds from the NNW, 16 to 19 mph, with swells hanging around 3.3 ft to 3.9 ft, short periods of 5 to 7 seconds, and energy mostly in the 100s.

Then we hit the second week. Sunday the 9th of August the swell starts to build – morning gets 5.6 ft from the NNW, period 6 seconds, energy 314 (moderate), but the wind is a strong 16 mph from the N, cross-on, messy. Afternoon pumps to 6.9 ft from the NNW, period still 6 seconds, energy 352, but wind is 22 mph from the NNW – fresh cross-on and lumpy. That’s too big for beginners, and the wind ruins it.

Monday the 10th of August is the biggest swell of the period. Morning 7.2 ft from the NNW, period 9 seconds, energy 725 – that’s strong wave energy. Wind is 25 mph from the N, cross-on, strong and messy. Afternoon 6.9 ft, energy 797, wind 28 mph from the N. This is only for experts, and even then, the wind is howling. Not a good surf day. Kite surfers might be into it, but for paddle surfing, it’s a no-go.

Tuesday the 11th: swell drops to 5.2 ft and 4.9
