The Lowdown
Alright, I’m looking at the forecast for Foz do Lizandro and there’s really not a lot to get excited about. The whole 16-day window is pretty much a write-off for decent surf. We’re looking at a solid run of days with poor conditions, and the energy is just too weak to make anything work.
Right from the start, on Sunday the 19th, we’ve got a tiny 3 ft swell from the NNW with a short period of 6 seconds. The combined swell energy is a weak 66, and it’s got a cross-onshore wind blowing at 12 mph. That’s just choppy, messy, and no good for anyone. The water temperature is 69°, which is about normal for the time of year, nothing unusual there.
The whole first week, from Sunday the 19th all the way through to Saturday the 26th, is a gap of nothing but poor surf. The swell heights barely get above 1 ft, and the winds are mostly cross or cross-onshore, keeping things bumpy. The energy is consistently low, with values like 25, 80, 23, all under 100, meaning it’s just weak, weak, weak.
The second week doesn’t offer much hope either. There’s a tiny uptick on Sunday the 2nd of August, with a 1 ft to 2 ft swell from the WNW, period 12 seconds. The combined energy hits 146 on the afternoon, which is moderate, but the wind is still cross at 15 mph, so it’s likely still lumpy. The swell direction is WNW, and the optimum for Foz do Lizandro is SW, so it’s not even coming from the right angle.
Honestly, there’s no standout. The best-looking day might be the morning of the 29th, when the wind is light, cross-offshore from the NE at 6 mph, giving clean conditions. But the swell is just 1 ft from the WNW with a period of 11 seconds, and the energy is only 25. That’s barely a ripple. For a spot that’s a river mouth, it’s inconsistent, and you’d be scratching for anything rideable.
This is a classic blank run for the area. It tends to happen, but forecasts can change. For now, I wouldn’t bother waxing up. Hang tight, Rusty.
