The Lowdown
Grab your board, it’s Atalaia (Molhes) calling the shots for the next couple of weeks. We’ve got a mixed bag here, with a few bright spots scattered through the period, but it’s not all good news. The first week is mostly a write-off, with a lot of poor conditions and choppy, messy wind. The water’s sitting at 68°, which is pretty normal for this time of year, so no surprises there.
The only real standout comes on Tuesday morning, 15th September. We’ve got a solid 6ft swell from the SSE, with a period of 8 seconds and a combined energy of 570 (moderate). The wind is a clean cross-off from the WSW at just 3 mph. That’s going to produce some punchy, clean waves with decent shape. The swell is a bit on the bigger side for beginners, but intermediate surfers should have a blast. It’s a beach/jetty setup, so expect some decent peaks. Crowds are possible here, so don’t be surprised if you’ve got company.
Later in the week, on Thursday afternoon, 17th September, we get a real treat. There’s a very long-period groundswell from the SE blowing in at 18 seconds, with a combined energy of 393 (moderate). The swell height is only 2ft, but that period is going to create some long, clean lines, especially on the point. The wind goes glassy, with a light SSE breeze at 3 mph. This is a classic setup for a point break or reef, and the waves will be smooth and lined up. Keep in mind, with such a long period, the sets might be spaced out, so bring your patience.
The rest of the forecast is a bit of a struggle. There’s a lot of poor surf days with onshore winds and chop. A few mornings have clean conditions, like the 7th and 9th September, but the swell is too small or weak to get excited about. The 14th September afternoon sees a massive 10ft swell from the S, but the wind is cross-on and the period is short at 8 seconds, making it a big, messy, challenging day for experts only. The 15th September afternoon is also a letdown, with a small, weak swell.
Overall, it’s a slow start, but the 15th and 17th are your best bets. The 15th is the pick for power and punch, the 17th for pure, clean lines. Stay patient.
