The Lowdown

Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for a proper surf at Praia das Macas. We’ve got a lot of onshore wind and messy, lumpy conditions lining up, and not a lot of quality to get excited about. It’s one of those stretches where you might be better off doing something else with your time.

The first real window we can even talk about is Thursday the 14th. The swell is on the push, coming in at 7ft from the NNW with a period of 8 seconds. The energy is starting to build, with a combined energy reading of 539, which is moderate. But the wind is on it from the WNW, so it’s going to be a bit of a mess. It’s a marginal call at best, and definitely not one for the faint of heart. The afternoon bumps up to 8ft from the same direction, with energy jumping to 715, but the wind goes cross-on from the west, so it’s still going to be lumpy and tough.

Now, here’s where things get interesting. Saturday the 15th, in the morning, is the standout of this whole period. The wind swings around to a light S at 3 mph, which is cross-offshore. That’s going to clean things right up. The swell is a solid 7ft from the NNW with an 8-second period. The energy is strong at 487. This is the one to circle on the calendar. It’s going to be a bit on the bigger side, so maybe not for the beginners, but for the rest of you, this is your session. The morning is the call, because the afternoon wind swings to the SW and messes it all up again.

Sunday the 16th has a similar story. The morning offers another chance with a 7ft NNW swell and a light S cross-off breeze. It’s clean, but the tide and conditions are a bit questionable, so it’s not as solid a bet as Saturday morning. The energy is strong at 669, but that afternoon wind from the SSW is going to chop it up.

Monday the 17th morning is still in the mix, with a 8ft swell and a light SSW cross-shore wind. It’s workable, but the magic is gone. The energy is still strong at 632, but the quality is dropping off.

After that, the wind just kills it. The 18th and 19th see the swell staying in the 7ft range, but the wind is onshore or cross-onshore the whole time, and the energy climbs to very strong levels, hitting 924 on the 19th. With all that wind and size, this setup is going to be a washing machine. At that point, it’s looking way more interesting for the kite surfers than for us paddle surfers.

The water temperature is sitting at 67°, which is a bit colder than normal for this time of year. It’s not crazy, but you’ll feel it. Grab the thicker suit.

So, to sum it up: the next week is a write-off. The real action is on Saturday the 15th morning. That’s the one. Sunday morning is a backup, but the forecast confidence drops the further out we go, so keep your fingers crossed. For the long-range stuff, it’s promising but far from certain. Don’t get your hopes up too high for the middle of next week; that’s looking like a blown-out mess.

Stay patient, check the buoys, and I’ll see you out there.
