The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening for the Zambujeira do Mar zone over the next couple of weeks.
Honestly, the first week and a half is a real bummer. From Thursday the 6th all the way through to Tuesday the 18th, it’s quiet. The swell is small, the wind is mostly cross or cross-on, and everything is listed as poor surf conditions. The combined wave energy is weak, staying under 300 most days, with a lot of it reading under 100 (like 44 on the 11th morning). The wind is a constant problem, with a 12 mph breeze from the NW or NNW putting a chop on the surface. There’s just nothing to get excited about for a paddle.
But then, things change. The standout window is the morning of Wednesday the 19th of August. This is the one to mark on the calendar. We’ve got a clean 5 ft groundswell rolling in from the NW, with a period of 9 seconds. The wind goes glassy – a light air from the SW – and that’s exactly what we want. The combined energy jumps to 445 (moderate), which tells you there’s some proper push in the water. This is the best chance you’ll get for a clean session, with the swell direction matching the break’s optimum WNW. If you can only get one day, this is it.
The morning after, Thursday the 20th, is still surfable but a step down. The swell drops to 3 ft from the WNW, period at 7 seconds, and that glassy conditions are back in the morning. The energy is weak at 117, so it’s small, but it’s clean. Worth a look if you’re keen on a longboard or a foamie.
The last morning we see, Friday the 21st of August, has a 3 ft NW swell with a light cross-shore from the NNW. The energy is moderate at 163, but it’s still a far cry from that Wednesday morning stand-out.
So, the takeaway: the first 13 days are a washout. You’re waiting for the 19th morning. That’s the one. Get on it.
Rusty.
