The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the menu for Praia do Porto over the next couple of weeks.
It’s a bit of a slow start, but there’s some solid windows of clean surf coming up. The water is sitting at 62°, which is a bit colder than normal for this time of year, so you’ll want a decent wetsuit.
The pick of the whole forecast is Monday the 14th. We’ve got a morning session that’s looking tidy. The swell is coming in at a solid 5ft from the SSW with an 11-second period, giving us a moderate wave energy (1192). The wind is light offshore out of the southwest, so expect clean, lined-up waves. The afternoon goes glassy with a smaller 4ft from the south, but still worth a paddle. This is the standout window.
Tuesday the 15th is still good, with clean conditions on both the morning and afternoon sessions. The swell drops a touch to 3ft, but the period holds at 10 seconds, and the wind stays favourable. It’s smaller but clean – a good board-changer day.
Wednesday the 16th morning sees the swell bump back up to 5ft, but the period is short at 8 seconds. It’s still clean with offshore wind, so it’s surfable, but it won’t have the same grunt as Monday.
Now, from Thursday the 17th right through to Sunday the 20th, we’re in a poor run. Onshore winds and messy conditions mean you’re better off doing something else. The swell sticks around, but it’s just not worth it. A couple of those days see swell over 8ft, which is expert-only territory anyway, and the wind is rubbish.
There’s a light at the end of the tunnel. Monday the 21st has a glassy morning with a 7ft swell from the ENE. That’s a decent size, but the period is only 9 seconds, so it won’t have that long-period punch. Still, glassy conditions make it very tempting for the experienced crew.
Tuesday the 22nd and Wednesday the 23rd morning are pretty ordinary, but Wednesday afternoon is a real surprise. We get a jump to 8ft from the south, period still short at 8 seconds, but the wind is clean and cross-off. The wave energy is strong (830). That’s a fun, punchy afternoon if you’re keen.
The rest of the run into the end of September is mostly small or windy. Thursday the 24th and Friday the 25th are blown out. Saturday the 26th is tiny – 1ft – not worth getting wet for. Sunday the 27th afternoon brings a clean 5ft from the south with offshore wind, which is a nice little finish to the week.
And then Tuesday the 29th? Glassy start with 5ft from the SSE and an 11-second period. That’s a clean, fun morning with moderate energy (610). A good way to end the forecast.
Overall, the standouts are clear: Monday the 14th is your best bet, and keep an eye on Wednesday the 23rd afternoon and Tuesday the 29th morning for clean, fun waves.
Rusty.
