The Lowdown
Right, let’s have a look at what we’ve got for the Aventureiro region. The next couple of weeks are a real mixed bag, not much to get overly excited about for the first week, but hold on, we get something special right at the end.
Starting off, this Thursday the 3rd of September is a write-off. We’ve got a South swell pushing 6ft, but it’s getting hammered by onshore winds. The wave energy is there, but the quality is poor. Not worth paddling out.
Things look a bit more promising on Friday the 4th. The swell drops off to a clean 3ft from the SSE, and with a glassy morning, the break should be looking tidy. It’s a beginner-friendly, very consistent point break here, and the water temp is about average for the time of year. It’s a small window, but worth a look for a longboard cruise.
Saturday the 5th morning is glassy again with tiny 2ft waves, but it’s really small, more of a splash-around than a proper surf. The rest of the first week and into the next is a real mess of onshores and poor conditions, with the swell size bouncing around but the wind just ruining it. There’s a big patch of days where it’s just not recommended.
The first real standout arrives on Monday the 14th of September. A clean 4ft swell from the South, but the period is a very long 14 seconds. That’s proper groundswell energy. It’s glassy in the morning. This is going to be lined-up and clean at this point break. Keep an eye on it, as a long-period swell like this can turn a good wave into something special.
But the absolute winner, the one you circle on the calendar, is Wednesday the 16th of September. Don’t let the “cloudy” sky fool you. The wind will be light and cross-off, and we are looking at a solid 6ft South swell with a 13-second period. This is the pulse of the whole forecast. It will be strong, clean, and punchy. This is for the crew who know what they’re doing – not for beginners at that size. It’s the best bet by a long shot, and with it being a couple weeks out, there’s a bit of hope riding on it, but it looks perfect.
So, there it is. A slow burn with one absolute beauty of a day on the 16th if the forecast holds.
