The Lowdown
Alright, Rusty here. Let’s be straight with you – this outlook for Picao is a tough one. We’ve got a long, drawn-out stretch of small, weak surf and tricky winds. There is no standout period, and honestly, no true “go” days in the whole 16-day window.
We’re looking at Picao (Baia Formosa), a reef break that needs a decent swell to light up. Right now, through the whole forecast, the dominant swell is out of the East and East-Southeast, which isn't the optimum NE direction this spot wants. Combined energy values are mostly in the low to high 100s (162 to 310), which is weak to moderate energy at best. Water temp is about average for the time of year.
Let’s run through it. The first week is a total write-off. From Friday the 4th right through to Monday the 14th, we see nothing but “poor surf conditions.” Swell heights barely nudge above 1.0m to 1.5m (that’s 3 ft to 5 ft), with short periods of 5 to 8 seconds. That’s weak, windswell stuff. Winds are cross-offshore from the SE for much of the early days, keeping it clean, but there’s just no push. The afternoon of Saturday the 12th shows a “marginal” call with 1.4m (5 ft) from the E at 8 seconds and a combined energy of 273, but it’s still not worth paddling out for.
After Monday the 14th, it’s more of the same. A gap of several days with zero recommendations continues right through to the end of the forecast on Saturday the 19th of September. Swells stay under 1.2m (4 ft), periods stay short, and winds turn more cross-shore or cross-onshore from the E and ESE, adding a bit of chop. The energy is low, the swell direction is wrong, and the consistency is poor.
This is one of those times where the blank run is pretty normal for this area. There’s simply no surf on offer worth getting excited about. Keep the board in the bag, or maybe wax up a kite if you’ve got one – the cross-shore winds and small, weak surf at this beach-and-reef setup look more interesting for kite surfing than paddle surfing right now.
Stay patient.
Rusty.
