The Lowdown
Righto, let’s have a look at what’s on the cards for Praia do Porto over the next couple of weeks.
It’s a bit of a slow start, if I’m honest. The first few days are a write-off, but stick with me because this stretch has a few real moments. From Thursday the 6th through to the early part of the following week, the surf is either tiny or just messy with poor wind. We’re looking at a gap of about three days before anything worthwhile shows up.
The first real sniff of something good comes on Sunday the 9th. The morning sees a 7ft southerly swell, with a short period of 8 seconds, but the wind is offshore from the SSW at 15 mph. That’s going to clean things up nicely, and the combined energy is moderate at 966 – it’s punchy enough. This is a consistent spot, so it’ll be worth a paddle. The water temp is sitting at 67°, which is a touch warmer than usual for this time of year, about a degree and a half above average, so it’s pretty comfortable.
The run from Monday the 10th through Tuesday the 11th is the real standout window. Monday morning brings a 7ft southerly swell, period stretching to 12 seconds, and a gentle offshore from the WSW at 9 mph. The combined energy is moderate (1186), and the conditions are described as very good. That’s a groundswell with a nice long period, so expect some proper shape and power, though at a beach/jetty setup like this, a long period swell can sometimes close out a bit. Still, it’s clean and offshore – that’s your best bet. Tuesday morning keeps the same vibe: 6ft southerly, 11 seconds, offshore WSW wind at 9 mph, and clean conditions. The crowds are listed as “sometimes,” so you might have some company, but it’s not a circus.
A bit further out, Thursday the 14th morning looks like a proper treat for the experienced crew. You’ve got a 6ft SSE swell, a very long period of 14 seconds, and glassy conditions with a light offshore breeze. The combined energy is strong at 1508, and it’s rated as excellent for experienced surfers. That’s a groundswell that’s going to make the reefs and points sing, but at a beach break, be ready for it to jack up fast and run straight. This one is a promise, though it’s a week away, so keep an eye on it.
The end of the run, on Wednesday the 20th, offers another promising morning. A 6ft south swell, 14-second period, and glassy conditions with zero wind. The combined energy is strong at 1513, and it’s another call for experienced surfers as it’s excellent. That’s a long-range standout, so don’t lock it in just yet, but it’s got the look of something special.
Through the middle of the second week, the 15th to the 18th, the wind turns onshore and the swell gets bumpy. There’s a fair bit of size, with some 12ft days on the 17th, but it’s messy cross-onshore wind and poor quality – that’s more of a kite surfer’s playground than a paddle surfer’s.
Overall, the best of it is the three-day window from Sunday the 9th to Tuesday the 11th, with clean offshore winds and solid south swell. Thursday the 14th and Wednesday the 20th are worth marking on the calendar, but they’re a way off.
