The Lowdown
Alright folks, Rusty here. Let's talk about what's cooking at Praia do Porto. The start of the period is a bit of a dud, but we've got a few clean windows to chase, and one serious swell for the experienced crew later on.
The first few days are a total loss. Thursday the 30th and Friday the 31st of July are a washout with poor conditions and onshore winds. Saturday the 1st of August is no better, with a messy 7ft onshore NE swell that's all chopped up.
We finally get a break on Sunday morning, the 2nd of August. It's nothing special, but with a gentle offshore breeze from the SW and a clean 5ft swell from the ENE, it's rideable. The wave energy is moderate (226). Sunday afternoon cleans up with light cross-offshore winds.
The real highlights start next week. Tuesday morning, the 4th of August, is a gem. The wind goes dead calm, glassy, with a clean 3ft groundswell from the S. The period is a solid 11 seconds, and the energy is strong (376). The waves will be pure glass. That's the best of the early run.
Wednesday the 5th of August also looks good. Light offshore winds in the morning and a clean 3ft to 3ft S swell. The energy is strong (311). Not big, but clean and fun.
Now, for the experts, circle Monday the 10th of August. This is the big one. We’ve got a powerful 7ft S groundswell with a very long 13-second period. The combined energy is a massive 1455 – that's very strong. The wind is a light cross-offshore from the WSW, keeping it clean. This is serious, heavy surf. At 7ft it's only for experienced surfers. Monday afternoon drops to a still-chunky 6ft, but it's still a great option with clean conditions.
There's a long stretch of poor onshore wind from Friday the 7th of August through the 14th of August, with only small moments of clean surf. Tuesday the 11th of August morning looks glassy again with a 4ft S swell, but that's about it for clean conditions after the big Monday.
So, to sum it up: for the everyday surfer, the best bet is the Tuesday morning glass-off on the 4th of August. For the experienced crew, Monday the 10th of August is the day to be on it with that powerful groundswell. Get after it.
Rusty.
