The Lowdown
Alright, grab your coffee. It’s gonna be a mixed bag here. We’ve got a 16-day window ahead, and right now, things are looking flat and gloomy for the next few days. There’s a real dry spell in the forecast, so don’t expect much to happen.
After that, we finally start seeing some pulses of energy, but conditions are going to be a real battle. The standout, and honestly the only real highlight, is on Sunday the 15th at sunrise. Tuesday morning the 15th, we’ve got some clear skies and a light offshore breeze from the southwest. The swell is coming from the east at 6 ft with an 8-second period. The combined wave energy is moderate, sitting at 413. That offshore wind is crucial here – it’ll groom the face clean. Get on it early at Atalaia (Molhes) as that window is short – by afternoon, the wind swings onshore and messes it right up.
Then we have another shot on Saturday the 19th morning. There’s some cloudy skies and a clean cross-offshore breeze from the northwest with 5 ft of east swell. The energy is a bit weaker at 325, but clean conditions make it worthwhile.
Later in the run, we get a big jump in period. On the morning of Tuesday the 24th, we see a clean cross-offshore wind blowing from the south, with 3 ft of swell from the southeast but a very long 13-second period. The energy is strong at 275 – that’s proper groundswell lads. It’s small, but the quality will be there for a point or a reef if you can find the right sandbank.
For the weekend of the 20th, Sunday afternoon looks tidy – clear skies, a light cross-offshore from the west-northwest, and 4 ft of east energy (330). It’s a good, clean afternoon surf.
Honestly, there is very little here that stands out. The week of the 10th is poor to flat. Crowds at Atalaia can be a bit of a lottery, but with this up-and-down forecast, it could be manageable. No real big, clean swell days to write home about, so keep your expectations low and be ready to jump on those morning windows.
