The Lowdown
Alright, let me tell you what we’ve got coming up here. The next couple of days are a bit of a mixed bag, but if you’re patient, there are some real gems hiding in the second half of the outlook.
Right off the bat, first real chance to get a wave is Wednesday morning here at Praia do Aventureiro. It’s a point break, and it’s beginner-friendly and very consistent, which is a good sign. The water is sitting at a very warm 74°, a big jump from what’s normal – almost 4° warmer than usual for this time of year, so you can leave the thick suit at home. Wednesday morning we’re looking at clean, surfable waves around 4 ft from the SSW with a short period of 8 seconds. The wind is light offshore from the WNW, so it’ll be clean, but the energy is fairly weak (256). You can get a few rides, but it’s nothing to write home about.
The real standout, the one you should circle on the calendar, is Friday morning, September 4th. This is the best of the first week. The swell drops a touch to 3 ft from the SSE, but the period stretches to 11 seconds, giving it some proper push (moderate energy at 387). More importantly, we’ve got glassy conditions – that wind is a dead calm from the SSE at just 3 mph. That means mirror-smooth faces, no chop, just clean lines. This is your morning session. The afternoon stays clean too with a cross-off breeze, but the morning glass is the winner here.
Now, we hit a rough patch. From Saturday the 5th through most of the following week, conditions turn poor. We get a lot of rain showers, light rain, and onshore or cross-shore winds that chop everything up. Even though there’s a pulse of bigger swell (up to 7 ft) on Monday the 7th, the wind is a mess – moderate cross-onshore and choppy. Not worth the paddle-out.
But hold tight. The second week has a serious payoff. Tuesday morning, September 8th delivers another glassy morning. 5 ft from the south with an 11-second period, moderate-strong energy (615), and that lovely NE breeze at just 3 mph. The wind is dead, the swell has power – this is one of the two best windows in the whole outlook.
Then, another notable window appears on Wednesday the 9th and Thursday the 10th. On Wednesday morning, we get 4 ft from the ESE with a cross-off wind from the WSW – clean conditions. Wednesday afternoon goes glassy again at 5 ft (ESE, 6 seconds, moderate energy at 320). Thursday stays clean all day with 5 ft from the ESE and a consistent cross-off breeze. Perfect for a slow, fun session.
The very last chance is on Monday, September 14th. It’s a full day of clean surf. Morning is totally glassy with a calm wind and 4 ft from the SSW, and the afternoon has a light cross-off from the SW. Energy is solid (573). This is the final gift before the outlook closes.
There is another pulse on the 17th – a big 5 ft swell from the south with a very long 16-second period and strong energy (1440) – but the wind is a moderate cross-shore with chop, so it’s not a standout for clean surfing. A bit of a tease.
If you’re a beginner, stick to the smaller, cleaner mornings like Friday the 4th or Monday the 14th. The bigger stuff (over 5 ft) on Monday the 7th is more for experienced surfers. But honestly, the standouts are Friday morning the 4th and Tuesday morning the 8th – glassy, clean, and with enough push to make you smile.
