The Lowdown
Alright, Rusty here with a look at what’s coming up for Praia do Aventureiro.
It’s a mixed bag to start, but there are some absolute gems hiding in the second half of this run. The water’s sitting at about 73.2°, which is much warmer than normal for this time of year – a solid 3.8° above average, so you can leave the thick suit at home.
The first real sniff of action is Thursday morning, the 13th of August. We’re looking at a clean 6ft swell out of the south, with a nice 12-second period. The kicker? Glassy conditions, dead calm. That’s pure magic for a point break like this. The wave energy is moderate (1018), but clean, lined-up surf is on the cards. Not a standout size-wise, but the conditions make it a solid choice for a paddle.
Friday morning the 14th is a bit smaller at 5.6ft, but the wind is cross-off and clean. The swell’s still from the south with a decent 13-second period. Another session worth chasing.
Saturday morning the 15th looks punchier, with 6.6ft south swell and 13-second period, but the wind is onshore and it’s marginal. The afternoon turns to risk of thunderstorms and gets messy – I’d skip it.
Sunday the 16th and Monday the 17th are a write-off. Onshore junk, poor quality. Tuesday the 18th morning offers a tiny window of clean 5ft surf from the east-southeast with a short 8-second period and light cross-off wind – it’s clean, but weak.
Then there’s a real drought. From Wednesday the 19th through Saturday the 22nd, the swell drops way down, mostly under 3.3ft, with poor conditions. You’re looking at a 4-5 day gap where there’s almost nothing worth paddling out for.
But hold on, because things fire up again. Monday morning the 24th brings glassy conditions and a clean 6ft south swell. That’s a good start to the week.
The standout windows are Tuesday the 25th and Wednesday the 26th. Tuesday morning has 6ft south swell with a super long 15-second period, clean cross-off wind, and excellent conditions for experienced surfers. The wave energy jumps to a strong 1524 – there’s proper push behind it. That long period will make it a bit walled-up at the beach, but for a point like Aventureiro, this is prime territory.
Wednesday morning the 26th is the real trophy. We’re looking at 8.2ft of south-southwest swell, 13-second period, glassy as it gets. The energy hits a beefy 2520. This is big, powerful, and clean – for experienced surfers only. Crowds are possible here sometimes, but on a morning like that with that size, the pack will be thin. This is the one to circle on the calendar.
Thursday morning the 27th closes the run with another glassy session, 6.2ft of south-southeast swell, 12-second period, good energy (1393).
So the takeaway: the next few days are average to poor, with a real dead zone mid-period. But the 25th and 26th, especially Wednesday morning, are the real deal. Get that date locked in.
