The Lowdown
Alright, Rusty here. Let's break down the upcoming surf.
It's going to be a bit of a mixed bag at first, with some wind messing things up early on. The real standout window is Monday, September 7th, and Tuesday morning, September 8th. That’s where the gold is.
For Monday morning, Praia do Aventureiro (a point break) will have a solid 7.5ft southerly swell, with a nice long 11-second period. The wind is light and cross-offshore, so the waves will be clean. The combined swell energy is strong at (1176), so there’s plenty of punch. This is the pick of the forecast, but at that size, it’s a bit much for beginners – you’ll want to be on your game. The water is sitting at a pleasant 73.4°, which is a touch warmer than average for this time of year.
By Monday afternoon, it drops a touch to 6.2ft, but the wind goes glassy from the WNW. That is as perfect as it gets. The energy is still strong (736), giving you long, smooth lines. This is prime time.
Tuesday morning is also a great call, with 4.3ft of south swell, a 10-second period, and glassy NE winds. The energy is moderate (533), perfect for logging some smooth rides without getting hammered. Expect a few people in the water, as it's a popular spot.
After that, the surf drops off considerably. Wednesday, the 9th, offers small 3ft waves in the morning with glassy conditions – fun for a longboard but nothing to get too fired up about. By Thursday the 10th, we see a bit of a pick-up in period to 12 seconds on a 3.3ft south swell with clean cross-offshore winds, but the energy is moderate (367). It’s surfable.
Things get messy from Friday the 11th right through the weekend, with poor conditions and choppy seas. There’s a long stretch of pretty ordinary surf until Monday, September 14th, when we see a new pulse of 5.6ft from the SSE with an 11-second period. The energy is strong (723), but the morning wind is cross-shore and the afternoon turns choppy and cross-onshore, so it's a bit of a tease.
We then get another drop-off before a final interesting window on Friday, September 18th. The morning brings a chunky 7.2ft from the ESE with an 8-second period and cross-onshore wind – that’s a bit raw and lumpy, though the energy is very strong (1477). The afternoon shifts to a lighter 4.9ft but with offshore ENE winds and a much longer 13-second period, and the energy is still very strong (1316). That afternoon might clean up nicely for the more experienced crew looking for a late-session hit. It's one to watch.
Saturday, September 19th morning is marginal, but the afternoon cleans up with 3.3ft south swell, 12-second period, and clean cross-offshore winds. A decent way to finish the fortnight.
Overall, your best bets are Monday, September 7th, and Tuesday, September 8th. That’s the window I’d be marking on the calendar.
That’s it from me. Stay salty.
