The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Zambujeira do Mar.
To be straight with you, the first week is a bit of a write-off. From Friday the 7th right through to Friday the 14th, we’re looking at mostly poor surf conditions. The wind is constantly cross or cross-onshore, the swell is small and weak, and the combined energy is low (136 for the first session). The water is sitting at 68°, which is a bit colder than normal for this time of year. It’s not going to be fun out there, so save your energy.
There’s a real gap here. We don’t get anything worth paddling for until the morning of Saturday the 15th of August. Even then, it’s marginal with a 5ft swell from the NW and a period of 8 seconds, but it’s a little better.
The real standout window starts to open up on the morning of Sunday the 16th of August. The wind goes glassy, right out of the SW at just 3 mph. The swell is a solid 5ft from the NW, with a period of 8 seconds, and the combined energy is 270. That’s moderate energy, and with glassy conditions, it’s going to be clean. This is the best on offer so far.
Then, the morning of Monday the 17th of August is even better. We’ve got glassy conditions again, with a 5ft NW swell and 8-second period. The combined energy is up to 306. This is a proper surfable size, clean, and the wind is slight air. This is a standout for the whole outlook.
If you’re looking for a second peak, the morning of Thursday the 20th of August is also looking promising. Another glassy morning with a 5ft NW swell, 8-second period, and combined energy of 326. That’s the highest energy we see in the whole run. The morning of Friday the 21st of August is similar, with a 4ft NW swell, 9-second period, and glassy conditions. The combined energy is 311.
Just remember, the swell is short period at 8 to 9 seconds, so it’s going to be a bit more local wind swell than groundswell, but the glassy wind will make it clean. The break is very consistent, so you’ll get waves. It can get crowded sometimes, so expect company.
The afternoons in this second week are mostly a write-off, with the wind swinging onshore and chopping things up. The mornings are the ticket.
So, to wrap it up: the first week is a dud, but the second week has some real potential. The mornings of Sunday the 16th, Monday the 17th, Thursday the 20th, and Friday the 21st of August are your best bets. Get up early.
Rusty.
