The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Praia do Porto.
Alright, straight up, the next week and a half is a bit of a write-off. We’ve got a long stretch of poor conditions from Wednesday the 15th right through to Sunday the 19th. The wind is mostly onshore or cross-onshore, keeping things choppy and messy, and the wave quality is just not there. You’d be better off doing something else.
Things finally start to look up on Monday the 20th. That morning, we get a proper offshore wind from the SW at 9 mph swinging clean. The swell is a solid 7 ft from the NE, with a moderate wave energy (945). It’s not a massive standout, but after that dry spell, it’s the first real chance for a decent paddle. The wind is light and offshore, so the surface should be clean.
The next real highlight doesn’t come until Thursday the 23rd. That morning is a beauty – glassy conditions with the wind from the SW at just 3 mph. The swell is a smaller 3 ft from the S, but with that glassy surface, it’ll be super clean and fun on the right board. The wave energy is light (270), but for a relaxing session, it’s a treat.
Looking further out, Saturday the 25th morning brings a bit more size at 6 ft from the S, but the wind is cross-onshore, so it’s only marginal. There is a promising long-range window on the 27th, but the swell is massive – 8 ft from the SSE with a very long period of 15 seconds. That’s a serious amount of energy (3318), but it’s also blowing onshore, making it a choppy, expert-only affair. The period is so long it will likely be racing and straight at the beach, so it’s not really a recommend.
The best true standout window is on the morning of the 30th. A clean 3 ft from the SE with a 12-second period, a gentle offshore wind from the SW at 9 mph, and clean conditions. It’s small but refined, and the best-quality wave of the whole run.
The water temperature here is about 60°F, which is a whopping 6°F colder than normal for this time of year. That’s very unusual, so you’ll want a thick suit.
Stay patient, and get on that Monday the 20th or Thursday the 23rd morning session.
Rusty.
