The Lowdown
Alright folks, Rusty here with a look at what's coming up for Picao (Baia Formosa). Let's be straight with you – this outlook is a tough one. The water temp is sitting around 81°, which is pretty average for this time of year, so no drama there.
The forecast period kicks off, and honestly, it's a long, quiet stretch. From Monday afternoon the 31st of August, we see a small window with a 5ft easterly swell pushing through, but it's got a short 8-second period and the energy is moderate at best (365). The wind is a cross-off from the southeast, which does keep things clean, but the overall quality is just marginal. After that, we're looking at a real dry spell. From Tuesday the 1st of September right through to Sunday the 13th of September, the guidance scores are all low. The swell stays small, mostly between 3ft and 5ft, with that short period from the east. The wind is a constant cross-shore or cross-off, which is okay, but the wave quality is consistently described as poor. It's a solid stretch of days where you're better off doing something else.
The best bet on offer, and I'm reaching here, is the very first session. Monday afternoon the 31st of August. That 5ft easterly swell with the cross-off breeze gives you the cleanest conditions we'll see. The energy is moderate (365), and while it's not a standout by any means, it's the only time the ratings are even worth a look. For a reef break that's consistent and fairly exposed to the swell, it's a disappointment that the direction is coming from the east when it really wants a northeast swell to line up right.
There's a slight uptick around the 10th of September, a Thursday afternoon, with a 5ft swell from the east-southeast, but the period is still short at 7 seconds, and the quality is still poor. The wind is cross-off and clean, but the waves just don't have the juice. From the 11th onwards, the swell drops right off, with a 1.0ft wave on the Friday afternoon – that's barely a ripple.
In short, don't get your hopes up. This is a long, quiet period for Picao. The only real chance for a surf is that first Monday afternoon, and even then, it's a marginal call. Keep an eye on the charts, but for now, it's a no-go.
Rusty.
