The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next stretch.
Honestly, I gotta be straight with you – the next 16 days are a real tough watch for paddle surfers around Praia das Macas. The wind is the enemy here, and it hardly lets up. Almost every session is blown out with cross-onshore winds, and the wave quality takes a hammering. The water temp is sitting at 70°, which is about 1° warmer than average for this time of year, so nothing crazy there, just a bit of a warm blanket.
We kick off Saturday July 25th with a 5ft NW swell (period 7 seconds) but the NNW wind is howling at 16 mph cross-onshore, making it a choppy, messy mess. The combined energy is moderate at 285. Sunday July 26th is even worse – a 6ft NNW swell (405 energy) but a 22 mph cross-onshore wind from the north, lumpy and ugly. It stays like this for days. Monday July 27th morning is the only real glimmer – a 4ft NW swell (235 energy), with a slight cross-shore wind at only 3 mph, so it’s nearly glassy. That’s your best bet for the whole week, but it’s still marginal. The rest of the week is a write-off with strong onshore winds and choppy, poor surf.
Moving into the next week, it’s more of the same story. The swell picks up significantly around Monday August 3rd with a 6ft NNW swell (463 energy) and Tuesday August 4th sees a 7ft NNW swell (500 energy) – there’s plenty of water moving, but the wind is still cross-onshore and fresh, so it’s lumpy and messy. By Wednesday August 5th, the swell hits 8ft (710 energy), but again, cross-onshore wind ruins it. This is big, powerful, and ugly – honestly, it looks more interesting for a kite surfer than a paddle surfer. Thursday August 6th morning has a 7ft NNW swell (566 energy) with a cross-shore breeze, which is the best late window, but still just marginal.
The standout here is Monday July 27th morning. That’s the only window where the wind drops out and you get a clean, light cross-shore breeze with a 4ft NW swell. It’s not pumping, but it’s the only rideable wave in the whole forecast. The rest of the 16 days is a blocked-out run of poor conditions, so don’t get your hopes up. If you’re desperate, chase that Monday morning – otherwise, it’s a long wait.
