The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for our local stretch.
Honestly, it’s a tough one. The next couple of weeks are looking pretty ordinary. We’ve got a real run of poor conditions stretching from Saturday the 5th right through to the end of the forecast. There’s a massive gap with no worthwhile surf on offer, day after day of lumpy, cross-shore wind and chop. The only real chance to get wet is a very brief window at the start, but it’s nothing to write home about.
Saturday, 5th September is the only time worth grabbing your board. Early morning at Foz do Lizandro (river) is your best bet. The swell is small at 3 ft from the WNW, with a period of 9 seconds. The combined energy is moderate (112). The wind is glassy from the NNW at 3 mph, which is a major positive – it’ll be clean. The water temp is about average for the time of year. The break is a river mouth, fairly consistent, and with a south-west optimum, this west-northwest swell is a decent match. It’s a beginner-friendly spot, but the crowds are sometimes an issue, so get there early.
By Saturday afternoon, the wind swings to a light cross-onshore, and the swell energy jumps up (252) but the quality drops. After that, it’s a no-go. From Sunday the 6th through to the 20th of September, it’s a write-off – strong winds, cross-chop, and poor surf quality dominate. Some days have a bit of height (like Monday the 7th with 5 ft from the WNW), but the wind is howling at 19 mph from the north, making it a lumpy mess. That’s one for the experts only, and even then, it’s not worth it.
The second week stays quiet. Small swells and onshore winds keep things flat and messy. The 13th of September has a tiny 0.3 ft swell from the south, but it’s accompanied by a fresh 19 mph breeze. Not worth the drive.
So, bottom line: if you can get out Saturday morning (5th September), you’ll find some clean, small waves at Foz do Lizandro. After that, put the board away for a while. Forecasts can change, but right now, this is a lean stretch.
Rusty.
