The Lowdown
Alright, Rusty here. Let's get into it.
Right off the bat, looking at the 16-day window for Zambujeira do Mar, it’s a real mixed bag. We’ve got some decent swell windows, but the wind is going to be a constant battle. For the first few days, it’s a write-off – poor conditions and onshore winds mean you’re better off doing something else. The first real chance of anything decent kicks off on Sunday the 23rd of August, but even then it’s a bit of a gamble.
The standout window is the morning of Saturday the 29th of August. That’s the one to circle. We’ve got a solid 6 ft swell from the NNW, with a period of 10 seconds, and the wind is a light offshore from the NNE. That’s clean, cross-off, glassy conditions. The wave energy is strong (501), and the forecast says “expect very good surf conditions”. This is your session. It’s the best on offer, hands down.
A close second is the morning of Friday the 28th of August. The swell is 6 ft from the NW, clean cross-off wind from the north (15 km/h), and good energy (519). A solid backup option if you can’t make the weekend.
Water temp is sitting at 69°, which is about 2° cooler than usual for this time of year. Nothing crazy, just a touch cooler than average, so you might want a thin spring suit for a dawn session.
Sunday morning the 23rd brings a bigger 7 ft WNW swell with a longer 12-second period, and the energy is very strong (1091). The wind is light cross-shore from the south, so it’s rideable but a little scratchy. A long period groundswell like this works best at a point or reef, but Zambujeira is a beach setup, so it might break a bit straight and close out in sections. Still, for the experienced guys, there’s power there.
After the 29th, the surf drops off into the first week of September. The mornings of the 4th and 5th show some 4 ft to 7 ft NW swell, but the wind is always cross-on or onshore, keeping things messy. Nothing worth getting excited about. It’s a flat, average run into the second week of the forecast.
So, to sum it up: the 28th and 29th are your sessions. Everything else is a battle with the wind. Zambujeira is usually consistent, so this dry spell is a bit of a bummer, but that Saturday morning looks like a proper reward.
Rusty.
