The Lowdown
Hey folks, Rusty here. Let’s be straight up: the next 16 days at Foz do Lizandro are a tough stretch. I’ve got to be honest with you – there’s virtually nothing rideable on the cards for most of the period. The first surfable day doesn’t show up until Monday, August 25th, so we’re looking at a gap of nearly two weeks with no good waves. A real bummer, I know.
The pattern is dominated by weak, short-period wind swell and persistent cross-shore winds. From Monday, August 10th, right through to Sunday, August 24th, we’re seeing tiny swell heights (0.3 ft to 4 ft), mostly from the NW and WNW, mixed with periods of 5 to 10 seconds. The combined wave energy struggles to get into the moderate range, mostly sitting between 68 and 338 (weak to moderate energy). The wind is a constant problem – cross-shore and cross-onshore, often a moderate to fresh breeze at 12 to 19 mph, making for choppy, lumpy conditions. The water is sitting around 69°F, which is just about average for the time of year.
Now, there is one solitary highlight. On Monday, August 25th, the early morning session at Foz do Lizandro (Portugal) looks absolutely magic *on paper*. We’ve got a glassy, clean morning with a light offshore breeze from the ENE at just 3 mph. The swell is a solid 7 ft from the NW with a period of 10 seconds, and the combined energy is a very strong 862 (moderate-to-strong energy). This is a proper groundswell. The problem is, at 7 ft, this wave is going to be a handful – it’s squarely in the expert-only zone, and it’s predicted to be too big for this break. That’s the catch. So while the conditions line up, the size might be overwhelming. It’s a long-range call, so treat it as a promising but uncertain prospect. The afternoon brings a cross-onshore wind that will mess it up, so it’s a one-shot morning deal.
Look, I’m not one to sugarcoat it. This is a lean run, but for this area, a blank couple of weeks isn’t unheard of. Forecasts can change, so keep an eye on it, but don’t hold your breath. If you’re desperate for a paddle, that 25th is your only real shot, and only if you’re experienced and ready for a big one.
Rusty.
