The Lowdown
Alright, Rusty here. Let’s have a look at what Praia do Porto has in store for us over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. The first few days are pretty grim with onshore winds and messy conditions. The first chance of anything decent doesn’t roll in until Saturday the 29th. That morning the wind swings offshore from the SW, cleaning up a 6 ft swell from the ENE at a short 8 seconds. It’s not a world-beater, but with the wind turning glassy by the afternoon (3 ft gentle offshore), it’ll be rideable and quiet. The energy is moderate (390). That afternoon is looking like the pick of the first week for a beginner-friendly paddle. Sunday the 30th keeps the small, clean vibe going but with light rain and a 4 ft swell, it’s very ordinary.
The real standout is Wednesday the 2nd of September. Tuesday the 1st builds a fresh offshore from the SSW, hitting 19 mph, and by Wednesday morning we’ve got a proper pulse. The swell jumps to 8 ft from the S with an 11-second period, producing strong wave energy (1468). It’s clean with a slight air offshore, making for excellent conditions for experienced surfers. This is the one to circle. The afternoon stays clean with a 7 ft SSE swell, but the morning is the winner for size and shape.
After that, Thursday the 3rd is still fun with a 6 ft S swell and light offshore wind (673 energy), but it’s a step down. Then we hit a dead zone from Friday the 4th right through to Tuesday the 8th of September. That’s five days of onshore wind and small, poor surf – nothing worth paddling out for. The energy drops off completely.
We get another sniff on Wednesday the 9th, with a 7 ft SSW swell and light offshore wind (648 energy). It’s clean but the period is a short 8 seconds, so it won’t have the grunt of the previous swell. Still, it’s a solid session for anyone who missed out earlier. The rest of that week remains marginal with onshore wind spoiling the show, though Friday the 11th offers a 8 ft E swell with cross-off wind, which could produce some punchy, clean waves despite only moderate energy (965).
Water temp is sitting at 64°F, which is about 1° cooler than normal for this time of year – nothing to stress about, just standard autumn cooling.
If you’re looking to get waves, aim for Wednesday the 2nd of September. That’s the best on offer.
Rusty.
