The Lowdown
Alright, Rusty here again with the Imperial version. Let's talk about what's on the table at Atalaia for the next couple of weeks.
The real standout of this whole stretch is the morning of Wednesday, August 26th. This is the one to wake up for. We're looking at a 7ft swell out of the south-southeast. The wind is dead calm – glass floor – so the surface will be like a lake. Wave energy is strong at 1021. The swell is short period at 8 seconds so the waves will be a bit lumpy and dumpy, but with those clean conditions, Atalaia (Molhes) will have some serious punch for experienced riders. It's a bit on the bigger side, so not a beginner's day.
Leading up to that, the best early option is Thursday morning, August 13th. We have a waist-high 3ft swell from the southeast with a lovely 15-second period – that's true groundswell that'll offer long, smooth rides. Winds are glassy from the south. Energy is moderate at 394. Water temp is 19°, which is normal for this time of year.
Monday morning, August 17th, serves up a 5ft east swell with 8-second period. The wind is cross-off from the north-northwest and it'll be clean. Energy is moderate at 362.
Saturday morning, August 20th brings glassy conditions with a 3ft SSE swell, 11-second period, and energy of 359. Mellow and clean – great for a longboard.
Then Tuesday, August 25th is a beauty: both morning and afternoon have glassy southeast groundswell at 3ft and 3ft, both with 15-second periods. Energy is high (464 and 489). Long, clean walls for those who can find the lineup.
Now, as for the gaps: the first few days are quiet and the afternoons are generally blown out or onshore. Nothing worth getting excited about until the 13th. The Sunday, August 23rd afternoon shows a 7ft SSE swell with a massive energy reading of 1415 – that's a lot of water moving. But with onshore wind, it's more of a kite-surfing day for the brave, not a paddle session.
The clear winner is the 26th. Mark it on the calendar.
