The Lowdown
Alright, Rusty here again. Let’s break down the same outlook in feet and miles per hour.
We’re zeroed in on just one break: Atalaia (Molhes). The first stretch is nothing to write home about, but there’s a couple of days that are gonna be worth the paddle out.
Starting Monday, August 31st, we’ve got a tiny 3ft swell from the ENE, with a weak 8-second period. Monday morning is surfable but nothing special. The afternoon turns glassy, which is nice, but the waves are still small. Tuesday and Wednesday morning are clean with cross-off winds, and the swell builds to about 4ft by Wednesday morning. The energy is moderate (340), and it’s looking decent. Don’t get caught out Wednesday afternoon – the wind goes onshore from the ESE and kills it.
Thursday, September 3rd morning has a 3ft swell with a nicer 11-second period from the ESE. Clean conditions. Friday and Saturday are small and choppy, a total loss.
Now, here’s the one you’ve been waiting for. Sunday, September 6th morning is the big one. Glassy conditions, a healthy 7ft swell from the S with a 10-second period. The energy is pumping at 1105. That’s solid, powerful surf. The water temp is about normal for the season. At 7ft, it’s a step up, but not insane. The morning glass will be pristine. The afternoon gets onshore, so you gotta be out there early.
The second week starts with a clean 5ft S swell on Monday, September 7th morning (655 energy) – solid. Tuesday the 8th is a dud. Wednesday the 9th morning is glassy with a 4ft ESE swell – a good, clean option. Thursday, September 10th morning is another standout. Glassy, 6ft from the E (663 energy), with a 9-second period. That’s a beautiful morning. Friday, September 11th morning is also a contender with a glassy 5ft from the ESE (675 energy). The afternoons get choppy. The end of the run from the 12th to the 15th fades to small, marginal surf, with a final glassy Tuesday morning but only 3ft waves.
So, my two picks are Sunday, September 6th morning and Thursday, September 10th morning. Atalaia (Molhes) is a beach/jetty, pretty consistent, and it can get crowded, so expect some company for those good days.
Rusty.
