The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the cards for Atalaia (Molhes). The next couple of weeks are a mixed bag, but there are a couple of moments worth getting excited about. First up, we’ve got a tricky start. The water temp is sitting at about 66°, about average for this time of year.
For the first few days, it’s pretty bleak. Late August is looking rough with a messy 5ft cross-on swell and poor conditions, so you might as well leave the board in the car. That carries into the end of the month and the start of September with only tiny, ordinary waves on offer. The wind turns offshore on the morning of Tuesday the 1st of September, with a clean 3ft swell from the ENE, but it’s small and weak, with combined energy at 169, so it’s more of a log session than anything.
The first real standout comes on Wednesday the 2nd of September. We wake up to glassy conditions and a 4ft south-east groundswell. The period stretches to 11 seconds, giving the waves a bit of grunt, and the combined energy jumps to 444 – that’s moderate but solid. This is the pick of the early window. The wind is glassy, and the break should be clean and user-friendly for intermediates. Keep in mind, it’s a beach/jetty setup with that long period, so expect the waves to be a little more lined up, but watch for them to close out if it gets too straight.
The second week is a real wait-and-see game. There are some promising signals, but they’re further out. The morning of Sunday the 6th of September sees another glassy session with a 4ft south-east swell pushing through at a long 12 seconds. The energy is 379 – not huge but quality. Then Monday the 7th of September morning is worth a look: calm, glassy conditions, a 4ft south-east swell with a very long period of 14 seconds, and the energy jumps to 470. That’s a solid groundswell. Given the long period, this swell will work well at a jetty or river mouth, but at a beach break it might be a bit too straight and unpredictable.
Later in the week, there’s a massive pulse of energy on the 10th and 11th of September, but with onshore winds and poor conditions, it’s a write-off for us. The setup looks more interesting for kite surfing than paddle surfing if you’re into that.
Overall, the best bet is the morning of Wednesday the 2nd of September for a clean, glassy session on a modest but fun 4ft south-east swell. Keep an eye on Monday the 7th of September morning as a promising long-range option, but that’s less certain.
Rusty.
