The Lowdown
Alright, the wait has been a bit of a drag, but there is light on the horizon. The long-range models are starting to show a pulse of energy that will get our attention, but you’re going to have to be patient.
Let’s start with the here and now. The vibe is flat and frustrating. From Friday afternoon the 28th right through to the end of the first week of September, conditions are a write-off. The swell that tries to show up on the 28th is a chunky 7ft from the WNW, but with a moderate cross-onshore breeze, it’s a choppy, bumpy mess. The water temp is sitting at a pretty mild 68°, which is a touch cooler than average for this time of year, but nothing crazy.
After that, it’s a brutal stretch. From Saturday the 29th all the way until Tuesday the 8th of September, there’s nothing worthwhile. The swell collapses completely for a solid week. The combined wave energy drops to these tiny two-digit numbers like 20 mm and 22 mm – that’s not even enough to get a ripple going. The wind stays cross or cross-onshore, and the period is either short or just not lining up. It’s dead, flat, and lifeless. This is a normal pattern for the area when the summer lull sets in, but it doesn’t make it any easier to swallow.
Now, here’s where it gets interesting. Eyes on Tuesday morning the 8th of September. The models are promising a fresh 6ft WNW groundswell rolling in. The period is a solid 11 seconds, which is just long enough to pack a punch and will start to wrap into the river mouth at Foz do Lizandro. The combined energy jumps to 640 – that’s moderate but lively energy. The wind is a cross-shore from the north at 12 mph, which isn’t perfect, but it’s not going to ruin it either. This is the standout of the forecast. It’s not for beginners though. Anything over 5ft gets a bit much for the learners, and this one is pushing that limit. The break is fairly consistent, but it can get a crowd, so expect some company. The direction is WNW, which matches the optimum SW direction fairly well for the river set-up.
After that little pulse, it fizzles out again. By Wednesday the 9th, it’s back to zeros. A tiny 3ft bump tries to show on Friday the 11th, but with onshore winds, it’s just messy.
So, in short: the next week is a total washout. The one shot you have is Tuesday morning the 8th of September. If you can get free, that’s the session to chase. Don’t hold your breath for anything else.
