The Lowdown
Alright folks, Rusty here. Let’s get into it.
First off, the water’s sitting at 67° which is a bit colder than normal for this time of year, so you might want a thicker spring suit.
We’ve got a long stretch ahead, and honestly, for the first several days, the surf at Foz do Lizandro is a write-off. From Tuesday 25th right through to the end of the month, we’re looking at a run of poor surf conditions. The wind is mostly onshore or cross-shore, lumpy, and the swell is a mess. The combined energy is weak to moderate (172 to 564), but it’s just not organised. The swell is short period, around 6 to 8 seconds, and the wind is either fresh or moderate, keeping things choppy. Don’t bother paddling out until the end of the week.
Now, Friday morning, 28 August is the first real standout. We’ve got a clean, cross-off wind from the NNE at 12 mph, and the swell is 8 ft from the WNW with an 11-second period. The combined energy jumps to 1490 (strong to very strong). This is a solid groundswell, but it’s a big one – only for experienced surfers. The wind is favourable, and the conditions are clean, but at 8 ft, it’s serious. If you’re a beginner, sit this one out.
After that, Saturday through Monday (29th to 31st) drops back to poor quality with cross-shore winds and messy, short-period swell. The combined energy sits between 163 and 302, but it’s all lumpy and cross-chop. Not worth the drive.
The next real highlight is Monday morning, 7 September. This is a long-range standout, so keep an eye on it. The wind is cross-off from the N at 19 mph, and the swell is 8 ft from the NW with a 12-second period. The combined energy is very strong (1915). Again, this is big and for experts only. The conditions are clean, but it’s a heavy day.
The rest of the window into early September is mostly small, messy, or too big with poor wind. The periods from 1 September onward are mostly cross-shore with lumpy conditions and weak swell. There’s a long gap of poor surf from the 4th to the 6th, with tiny swell (0.3 ft) and grinding cross-shore winds.
Overall, your best bets are Friday 28 August morning and Monday 7 September morning. Both are big, clean, and for advanced surfers only. The rest of the forecast is a struggle.
Rusty.
