The Lowdown
Alright, Rusty here, let’s break down what’s coming.
It’s a slow start, no doubt. For the first few days, there’s hardly anything worth paddling out for. You’ll be sitting on the beach for a while. The first real chance comes on the morning of Wednesday the 12th. We’ve got a 3ft SE swell with a light offshore wind out of the west – clean but tiny. Better suited for a log than a thruster. The swell energy is moderate (213).
Thursday the 13th morning is the one to circle. Glassy conditions with a 3ft SE swell, but the period stretches out to 15 seconds. That’s proper groundswell. The energy kicks up (326). At Atalaia (Molhes), a jetty/beach break, that long period might make it a little straight, but it’ll be the cleanest, most fun session of the first week.
Friday the 14th afternoon also looks glassy with a 3ft SE swell and a 14-second period. Good surf conditions again.
Then we go into a dry spell. Weak, short-period swell (8-9 seconds) and messy winds through the weekend and into the following week. Nothing to get excited about.
The real highlight comes on Tuesday the 25th morning. The wind goes dead calm, totally glassy, with a 4ft E swell. The energy jumps way up (424) – the most powerful we see. That short period (8 seconds) will make it punchy, and with zero wind, it’ll be clean and fun for intermediate surfers. That’s your best day of the whole outlook.
So, to sum it up: Thursday the 13th morning for the cleanest, lined-up conditions, or hold out for Tuesday the 25th morning for the most power and perfect glass. The rest is mostly a miss.
Rusty.
