The Lowdown
Alright folks, Rusty here. I’ve had a look at the charts for the next couple of weeks, and I’ll be straight with you – it’s a tough stretch. The forecast is pretty much a write-off for decent waves, so don’t get your hopes up.
There’s a long gap of no surf worth mentioning right from the start. We’re looking at a solid 16 days with nothing good on offer. The only break on the radar is Foz do Lizandro, a river mouth setup that’s best with a SW swell. Unfortunately, that’s just not what’s coming.
The water’s sitting about average for the time of year, nothing weird there.
The first few days are a bust. Monday the 3rd kicks off with a tiny 2ft swell from the west, but it’s a cross-onshore breeze and the combined energy is weak (60). By the afternoon, it’s a bit bigger at 3ft, but the wind is straight onshore and messy. Tuesday and Wednesday are more of the same – small, weak swell, never over 3ft, and the wind is either cross-onshore or a strong cross-shore that’s going to chop it all up. The energy stays weak, barely cracking 100 on the 4th, then dropping right off.
Thursday the 6th through the 10th is a flat spell with swell barely reaching 2ft and energy readings down in the 20s and 30s. The wind is a constant problem, mostly fresh cross-shore breezes. It’s just not surfable.
We get a little blip of energy on the 12th of August, with the swell picking up to 3ft from the west and a 9-second period. The combined energy climbs to 123 (moderate), finally something to look at. But the wind is still a cross-shore breeze, making it choppy and offering poor quality. It’s still not a goer.
After that, it’s back to small, weak, and windy right through to the 18th. The swell never gets above 2ft, the period is short, and the energy is mostly in the teens and twenties. On the 17th, the wind hits 25 mph, which is just a mess.
The only thing I can say is that the setup would be more interesting for the kite surfers than paddle surfers. For us, it’s a blank run. Foz do Lizandro is fairly consistent as a break, so this kind of run is a bit of a rarity. It’s not going to stay poor forever, forecasts can change, but for now, there’s nothing to get excited about.
Rusty.
