The Lowdown
G’day, Rusty here. Let’s have a look at what’s coming our way at Praia do Porto. The next 16 days start off pretty average, but there’s a strong run of swell in the second week that’ll get the pulse going, though it’s gonna be a handful. The standout is crystal clear: you’ll want to be in the water early on Sunday, 6th September, when the stars align.
For the first week, it’s a mixed bag. Sunday morning the 30th August is glassy with a small 4ft ENE swell (185), but the energy is weak and the conditions are pretty ordinary. Monday the 31st pushes up to 8ft from the east (652-801), but with heavy rain and onshore winds, it’s not worth the effort. Tuesday morning the 1st September brings clear skies and glassy conditions again, with a 6ft ESE swell (493) and clean lines—a decent option for a beginner-friendly wave, but nothing to write home about.
Now, Wednesday morning the 2nd September is where it starts to get interesting. You’ve got an offshore wind from the SW, clean conditions, and a 5ft SE swell (846). The energy is moderate, the waves are clean, and it’s a solid choice for a quieter session.
But the real highlight lands on Sunday the 6th September. The morning session has a solid 10ft S swell at 11 seconds, with clean offshore wind from the SW (2496). The combined energy is strong, and the setup is excellent for experienced surfers. The afternoon pushes to 12ft at 13 seconds (3900), with a cross-offshore wind—still clean but the swell is gettin’ big. This is expert territory only, and the long period (11-13 sec) suggests better shaped waves and longer lulls, so pick your peak carefully. It’s a beach/jetty setup, so this size might be more interesting for kite surfing if the paddle-out looks too gnarly.
Monday the 7th September keeps the big stuff going: 12ft at 14 seconds (4467) in the morning, and 12ft at 16 seconds (6008) in the afternoon—very long period groundswell. The energy is very strong, but the wind is cross-offshore and the break is going to be charging. Again, experts only, and the long period will make it fat and fast at this beach break, so treat it with respect.
After that, the week tails off with onshore winds and poor conditions from the 8th to the 11th. There’s a brief glassy window on Saturday afternoon the 12th September with a small 5ft E swell (279), but the period is short at 6 seconds, so the waves will be a bit fat.
Overall, the standouts are Wednesday the 2nd September for a clean, moderate day, and Sunday the 6th September for the quality big swell. The water temp is about average for the time of year, so no surprises there. If the crowds show up (and they sometimes do at Praia do Porto), the good windows will still have plenty of waves to go around.
Stay safe, and I’ll see you in the water.
