The Lowdown
G’day, it’s Rusty here. I’ll be straight with you – this forecast for Foz do Lizandro is a tough one. For the first week, from the 7th of August through to the 14th, the wind is a persistent problem. It’s mostly cross or cross-onshore from the NNW, with speeds from 12 to 19 mph, and the swell is just too small, mostly around 1ft to 3ft, with weak wave energy (66 to 151). The water is a mild 69°F, which is about average for this time of year, but the chop and lumpy conditions mean there’s nothing worth paddling out for. Every single session in that first block is marked as poor surf conditions. It’s a real bummer.
Then there’s a gap. From the afternoon of the 14th right through to the morning of the 20th of August, there’s effectively no surf on offer. The swell drops to tiny 0.3ft to 1ft, with very low energy (10 to 48), and the wind is either onshore or glassy with nothing to ride. You’re looking at about five days of flatness.
The one standout in this whole 16-day window is the morning of Saturday the 15th of August. That’s the only time the wind goes glassy, with a light westerly breeze at just 3 mph. The swell jumps to 5ft from the NW with a period of 9 seconds, and the combined wave energy hits 436 – that’s strong energy. The conditions are described as glassy, and the forecast says expect good surf conditions. This is the best on offer, and honestly, it’s the only one worth chasing. The water temperature is still around 69°F, so pretty normal for the season. Foz do Lizandro (river) is a beginner-friendly spot, and it’s fairly consistent, but it can get crowded sometimes. For this morning session, the clean conditions and that solid NW swell will make it work. The only catch is that this is over a week away, so treat it as promising but not locked in.
After that, from the 15th afternoon onward, it goes back to tiny, weak swells and messy winds, with a few cross-shore and cross-onshore days from the 20th to the 22nd that bring a bit more size (4ft to 7ft) but the wind is too strong (19 to 25 mph) and lumpy. That 7ft on Friday the 21st morning is big, but with 19 mph cross-winds and a fresh breeze it’s going to be a mess – more for kite surfers than paddle surfers.
So, bottom line: you’ve got one shot on the 15th of August morning. Make it count.
Rusty.
