The Lowdown
Alright folks, let’s talk about what’s coming up for Praia do Aventureiro over the next couple of weeks. Grab a coffee and settle in, because we’ve got a bit of a mixed bag ahead.
First up, the water temp is sitting at 73°, which is a solid 4° warmer than usual for this time of year. That’s noticeably warm, so you might not need the thickest wetsuit.
The forecast gets going on Monday, August 10th, but it’s a tough start. We’ve got 7 ft of south swell with a 12-second period, and the combined energy is moderate-to-strong at 1144. But the wind is cross from the SSE, and the surface is already getting chopped up. It’s messy, and the call is marginal at best. Not the kind of day to get excited about.
Tuesday, August 11th, is a little better. The swell sticks around 7 ft from the south, still with a solid 13-second period, and the wind shifts offshore from the ESE. The energy jumps up to 1469 in the morning. It’s still a bit marginal, but with offshore wind and that size, there will be some cleanish waves for the more experienced crew. By the afternoon, the swell pushes to 8 ft and the wind stays offshore, but the quality is still just okay.
Wednesday, August 12th, the swell drops a touch to 6 ft but the wind stays offshore from the ENE. The energy is moderate at 1036 in the morning and 1657 in the afternoon. It’s rideable, but nothing to write home about.
Thursday, August 13th, the swell eases to 6 ft, and the wind in the morning is cross-on from the NE. The energy is moderate at 946. The afternoon gets worse – the wind picks up cross-onshore from the SE and it gets choppy. Poor conditions.
Now, here’s a little glimmer. Friday morning, August 14th, is glassy. The swell is 6 ft from the south, 13-second period, and the wind is light from the SSW, making it glassy. The energy is 1026. This is the best window in the first week. The forecast says “expect very good surf conditions.” It’s a standout, but it won’t last – the afternoon turns cross-onshore again.
Saturday, August 15th, starts with another glassy morning. The swell drops slightly to 5 ft, still with a 13-second period, and the wind is light from the NE. Energy is 910. Another clean morning, but again, the afternoon goes cross-onshore.
Sunday, August 16th, the swell drops to 3 ft, but the morning is glassy with a light NNW wind. The period is 11 seconds, energy is 508. It’s small, but clean. Good for a longboard or a funboard session.
After that, the surf drops off hard. From Monday, August 17th, through to Thursday, August 20th, the swell is tiny – 3 ft, 2 ft, 2 ft – with poor conditions and weak energy. That’s a solid four-day gap with basically nothing worth paddling out for.
Then, on Friday, August 21st, we get a sudden pulse. The swell jumps to 6 ft from the SSE, with a very long 15-second period. The combined energy is strong at 1840. The wind is cross-off from the SSW, and the conditions are clean. This is the other standout in the outlook – excellent surf for experienced surfers. The long period means it’ll be a proper groundswell, so it will wrap in nice and clean. Just be aware, with that size and period, it’s on the edge of expert territory for a point break.
After that, Saturday, August 22nd, drops back to 4 ft with cross-onshore winds, and it’s poor again. Sunday and Monday are small and weak, with short-period windswell. The energy is low, and the conditions are poor.
So, to wrap it up: the first week has a few glassy mornings that are worth a look, especially Friday August 14th and Saturday August 15th. The second week has a real spike on Friday August 21st that could be the best of the whole run, but it’s more than a week away, so keep an eye on it. The rest of the time is a lot of small, weak, or messy surf. The break is a point, so it handles the south swell well, but it’s inconsistent in the long run.
Stay tuned, and keep your board waxed for those two mornings.
