The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Atalaia (Molhes).
Right off the bat, the next week and a half is gonna be a real struggle. We’ve got a long gap with next to nothing worth paddling out for. The first real glimmer doesn't show up until the morning of Wednesday the 24th, and even that is just ordinary, ankle-to-knee high stuff at 2ft from the SE with a nice, long period of 13 seconds. The water temp is sitting at 66.7°, which is right on the money for this time of year – no surprises there.
The true standout, the one to circle on your calendar if you can wait, is the morning of Friday the 25th of September. That’s where it finally comes together. We’ve got a clean, glassy morning with light offshore winds from the NNW. The swell is a very tidy 3ft from the SE, but with a very long period of 14 seconds. That kind of groundswell energy (399) will make for some proper lines wrapping in, though keep in mind that with that much period at a beach/jetty setup, it might be a bit straight for some spots. Still, on a good tide, this is the pick of the forecast.
After that, the morning of Sunday the 27th of September is worth a mention too. Another glassy morning with a 2.5ft SE swell at 11 seconds and decent energy (349). It’s not as special as the Friday, but it’ll be clean and fun.
Before all that, we’ve got a run of messy conditions courtesy of onshore winds and short-period windswell. Saturday the 19th and Sunday the 20th see some size (5ft to 7ft), but it’s all rain-lashed, cross-onshore junk. That 7ft on Sunday morning is way too powerful for beginners anyway, and with the wind all wrong, it’s just a washing machine.
Stay patient, lads. The end of the month is where it’s at.
