The Lowdown
Alright folks, Rusty here. Let’s be honest, this 16-day run for Foz do Arelho is a tough one to write. The forecast is a real mixed bag of poor conditions, with only a tiny window that’s worth paddling out for. Don’t get your hopes up for clean, consistent waves.
The water’s sitting at 70°, which is a touch warmer than normal for the time of year, so at least the temperature is on our side for the one decent session we’ve got.
Things start slow on Sunday the 26th. We’ve got a fresh 19 mph cross-onshore wind making a mess of a 6 ft swell. It’s a no-go. The energy is weak (347), and the period is short. Just leave the boards in the car.
Then, a brief glimmer of hope arrives on Monday morning, July 27th. The wind drops to nothing, dead glassy. That’s a major positive. The swell is a clean 4 ft from the NNW with moderate energy (250). It’s your only chance for a clean, shoulder-high wave, perfect for a beginner. But pay attention – this break is inconsistent, so you’ll be sitting and waiting for the sets. And sometimes it gets crowded, so expect company.
Everything after that falls apart pretty quickly. From Monday afternoon all the way through the end of the outlook on August 10th, it’s a string of cross-onshore winds, lumpy conditions, and “poor surf” stamped across every session. That’s a solid 13-day gap with nothing worth chasing.
Even when the swell gets a bit of punch, like on Thursday, August 7th, with a 5 ft NNW swell pumping out strong energy (558), the 16 mph cross-onshore wind just shreds it. The same story repeats on the 1st and 2nd of August – plenty of swell energy (over 450), but ruined by moderate cross-shore winds. It’s more of a windy, messy beach setup that might be fun for kite surfers than anyone with a paddle.
A few sessions around August 6th see a 12-second period groundswell with big energy (518), but again, the wind is on it, and the forecast says “poor surf conditions.” Long-period swell like that would be best on a point or reef, but here it’ll just be blown-out lines.
And that’s it, folks. One glassy morning is your best shot. After that, the wind is relentless.
Rusty, signing out.
