The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got at Foz do Lizandro for the next couple of weeks.
To be honest, the first few days are a washout. Wednesday the 26th and Thursday the 27th are ugly – onshore winds, lumpy water, and the swell is short-period junk around 5 to 7 seconds. The energy is weak to moderate (92 to 598), and conditions are poor. Not worth paddling.
Things finally perk up on Friday the 28th. We get a clear morning with light offshore wind out of the WNW at 6 mph, and the swell comes up to about 7ft with an 11-second period (energy 1144). That’s proper long-period groundswell. But here’s the deal – for a beginner spot like Foz do Lizandro, 7ft is getting big. The wind and tide are favorable, but the size is predicted to be too much for this break. By afternoon it goes cross-onshore, so it’s not clean. If you’re a solid surfer, the morning of the 28th is the one real standout – clean, decent power. For the average surfer, it’s a handful.
Saturday the 29th through Monday the 31st slides back into mediocrity. Cross-shore winds and lumpy conditions. Sunday morning the 30th has cleanish waves around 4ft but with an 8-second period, it’s weak and boring (energy 145). Monday the 31st gets stronger north wind up to 22 mph, messy.
Then we hit a flat spell. Tuesday the 1st of September is nearly flat with tiny 0.7ft swell. That flatness continues through Thursday the 3rd, with glassy conditions but no waves – literally 0.7ft and 0.3ft. A few days of total nothing.
Things trickle back from Friday the 4th with small waves around 3ft from the NW, but still weak (energy around 139 to 89) and cross-shore breezes. Nothing special. Saturday the 5th is similar, small and clean-ish but hardly worth it.
The best of the second week looks like Sunday the 6th of September. We get a glassy morning with a SE breeze at 3 mph, swell at 3ft from the WNW with a 10-second period (energy 138). That’s clean and surfable, but very ordinary. The afternoon goes onshore, so get in early if you want a slow, clean session. Monday the 7th drops back to small, weak onshore conditions.
Into the second Wednesday and Thursday (9th and 10th), it’s tiny again – 0.7ft to 1ft. Forget it.
Overall, the only real highlight is Friday morning the 28th of August. It’s clean with light offshore wind and proper sized swell (7ft, 11-second period from the WNW). The full energy is moderate (1144). But that wave is too big for beginners, and it’s a river-mouth setup. For experienced surfers, it’s the one session to aim for. Everything else is small, weak, or messy.
Forecasts can change – especially a week out – but right now, it’s slim pickings.
Rusty.
