The Lowdown
G'day, Rusty here. Look, I've got to be straight with you—this 16-day stretch for the region is a bit of a write-off. There's simply no good surf on offer, right from the start. The first record is Wednesday, August 26th, and it's all downhill from there. We're looking at a solid 16 days of poor surf conditions, with only a single day on September 1st that even nudges into "marginal" territory, and even that one is a bust.
The only spot on the radar is Picao (Baia Formosa), a consistent reef break that's fairly exposed to the swell. It's an intermediate-level wave, but you won't be needing your board for this. The ocean is mostly flat and messy. The wind is a constant problem, blowing cross or cross-off from the SE and ESE at 12 to 16 mph every day, which just ruins any chance of clean lines. The swell is tiny, hanging around 3 ft to 5 ft from the east, with a short, weak period of only 6 to 8 seconds. The combined energy of all swells is low, mostly sitting between 126 and 330—weak stuff.
The water temperature is a balmy 81°, about normal for the time of year, but you'll be spending more time floating than surfing.
The only glimmer is on Tuesday, September 1st. The morning shows a bump to 6 ft from the ESE, with a period of 8 seconds, and the combined energy jumps to 770—that's moderate wave energy. But it's described as "marginal" and the wind is still a cross-shore mess at 12 mph. There's no standout here. It's not worth a paddle.
For a stretch like this, with no consistency and no decent swell, it's a blank run that's pretty normal for the area. It tends not to stay poor for long, so keep an eye on the forecasts, but for now, I'd say find something else to do.
Rusty.
