The Lowdown
Alright, mates, Rusty here. Let’s have a look at the upcoming stretch. It’s a bit of a slow burner to start, but hang tight because there’s some serious juice on the horizon.
The first few days are pretty ordinary. Tuesday kicks off with a weak and bumpy 5ft swell, and you’d be fighting a cross-off breeze for a messy peak. Not worth the paddle. Wednesday morning shapes up a bit better—a clean 7ft from the SE with a light offshore wind (10 km/h) and moderate energy (800). That’s your first real window, but it’s not the main event.
We’ve got a lull coming through Thursday and Friday, with the swell dropping off and the wind going onshore. The water’s around average for this time of year, so nothing weird there. You’d be scratching for anything rideable.
Then we start to see the ocean wake up. The weekend brings back some clean, smaller swell in the 4ft to 5ft range with offshore winds, but it’s still building. The real standout is Monday the 7th. That’s the first day I’d get excited about—a solid 7ft of S swell, period pushing 10 seconds, strong energy (1490), and a gentle offshore breeze. Clean lines, proper push. That’s the one to circle.
Tuesday the 8th is also a gem. It’s a bit smaller at 6ft but glassy as a mirror with the wind dropping to nothing. Long period (11s) groundswell from the SSE, and the energy is still healthy (730). The wave quality could be exceptional, but remember that long-period swell tends to wall up at beach breaks, so the jetty might be your best bet for a decent line. This one’s a cracker.
After that, we get a couple of ordinary days with onshores and junky surf. Don’t bother.
Now, for the long-range promise. Around the 11th and 12th, the ocean goes off. We’re talking about a big pulse of S and SSW swell. It’s still a week out, so treat this as promising but not set in stone. Friday the 11th looks huge—10ft from the NE with a strong offshore wind (15 km/h) and massive energy (2436). That’s expert territory only, way too big for beginners. Then Saturday the 12th shapes up even better: 8ft of SSW swell, glassy conditions in the morning with only a slight air, and periods stretching to 12 seconds. The energy is pumping (1995). This is the other standout—a proper, powerful, clean swell. Just be ready for a crowd, as spots like this get busy when it’s good.
The tail end of the run stays solid, with 7-8ft swells and clean winds through Monday the 14th. But it starts to fade and get messy after that, with onshores returning by Tuesday.
So, bottom line: the first few days are a wash. Your two best windows are the 7th and 8th, and then the 11th through 14th for the bigger, more experienced stuff. The surf at Praia do Porto (Praiado-Porto) is fairly consistent for the region, so it tends not to stay flat for long. But this run has a clear build to it, and the payoff is worth the wait.
Stay salty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia do Porto may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
