The Lowdown
Right on, grab your board and let's talk Zambujeira do Mar. This is a spot that's normally very consistent, and over the next 16 days, it's going to try and deliver, but the winds are going to be the main story. The water temp is pretty average for this time of year, nothing weird going on there.
Straight up, this outlook is a bit of a mixed bag. The pattern shows we've got swell on the way, but most of it is compromised by onshore and cross-onshore winds, which will make things choppy and messy. There's a solid patch of moderate wave energy coming through, with values hitting around 463 to 617 (moderate), especially over the weekend of the 15th to the 16th, but the wind is just junk for surf. The swell direction is mostly WNW to NW, right in the sweet spot, but the wind is the enemy.
Things start off a bit soft. Thursday the 13th has clean morning conditions with a light breeze and a small 3ft WNW swell (period 10s, energy 203 - moderate), but it's just a marginal call with questionable tides. Don't expect much. Friday the 14th is the same story: a small 3ft swell in the morning with light cross-shore winds, but again, just a so-so prospect.
The real standout in this entire run is Thursday the 20th of August. This is the best window you'll see. We get a clean 3ft NW groundswell rolling in with a nice long period of 12 seconds, which will hold shape well. The kicker? It's glassy – dead calm in the morning. The energy is moderate at 345. This is your window for clean, lined-up waves at Zambujeira. Go get it. Later that day the wind swings onshore and the swell picks up to 5ft (moderate energy 623), but by then the session's done.
Looking further out, there's a bit of hope on Tuesday the 25th morning. The swell is back up to 5ft (NW, 9s), with just a light cross-onshore breeze, but the model flags it as marginal with a low score, so don't bank on it being amazing.
Other than that one Thursday morning, the rest of the run is a write-off for clean surf. The winds are consistently moderate to fresh from the NW or NNW, making for choppy, poor conditions. Even though the swell size gets up to 7ft on the 15th and 16th (energy 553-617), the onshore wind and short period (8s, 9s) mean it'll be a lumpy, bumpy mess. Not good for anyone.
Forget this for paddle surfing; save the energy. If there's any good news, it's that the break is very consistent, so a clean window like the 20th can pop up out of nowhere. Forecasts change, so keep an eye on that date.
