The Lowdown
Howdy, Rusty here. Let's cut to the chase – there’s no surf worth mentioning for the next two weeks. It’s a total flat spell in terms of quality.
The only spot we have is Praia das Macas. It’s a beginner-friendly wave, but even that won’t help you here. Every single day is plagued by a constant cross-onshore wind, mostly from the NNW or N, keeping things choppy and messy. The water is running at 67°, which is a bit colder than it should be for now.
Starting Tuesday the 4th, you’re looking at ankle-to-waist-high slop (around 3ft from the WNW, combined energy 142) being hammered by a 10-20 km/h onshore breeze. It’s poor. Wednesday through Friday sees the wind jump to 30 km/h and the swell (5-6ft from the NNW) turns into a complete lumpy, blown-out mess (combined energy around 400). That’s not surfable for anyone.
The rest of the first week and into the second is more of the same. We get a sniff of longer-period swell on Tuesday the 11th (3ft at 12 seconds, combined energy 231), but again, it’s cross-on and choppy. There is absolutely no clean window, no glassy morning, no standout day. It's just one “poor surf conditions” tag after another.
By Monday the 17th, we see another bump in size (6ft from the NNW, combined energy hitting 556), but by then the winds are still cross-on and fresh. For a beginner spot, 6ft is already pushing the limit, and with the lumpy conditions, it’s only suited for experts or kite surfers. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
Bottom line: there are zero good surf options in this outlook. It’s a blank run, and with no clean wind and constant onshore chop, it’s probably pretty normal for this spot when the wind doesn’t cooperate. Hang tight and keep an eye on the models.
Rusty.
