The Lowdown
Alright, grab your board, but maybe leave your hopes in the car for this one. This is shaping up to be a proper test of patience for Picao. The long-range window is looking real flat and wind-blown for the most part. We’ve got a long stretch of poor conditions on the cards, so don’t be expecting any magic sessions.
The next week to ten days is a write-off. From Monday the 10th right through to the following Monday, we are looking at waves that are too weak and shifty, with cross-off winds messing up any chance of a clean face. Sure, it’ll be around 3ft to 5ft in the water, but it's all short-period windswell and the energy just isn't there. We're seeing combined energy values in the low hundreds (like 109 to 207), which is just weak to moderate, and it’s just not pushing through with any conviction. The water temp is a warm 81°, which is about average for this time of year, so at least you won't be cold changing your mind.
The first real standout is way out there, a full week from now. I’m talking about Sunday the 16th. There’s a proper pulse of energy showing up, with combined energy jumping right up to 721. That’s a strong signal and it's bringing a bit more size, around 5ft, but the swell period is a long 12 seconds. Now, Picao (Baia Formosa) is a reef break, so this long-period groundswell is exactly what it wants. But, and it’s a big but, we've got cross-shore winds that morning and the forecaster is calling it marginal, with a cross-chop on the water. It's the only thing on the calendar with any real grunt, but it looks like it'll be a bit of a battle. If you’re an expert, it could be your only window.
After that, we slide back into the poor stuff. The energy drops, the swell backs off to 3ft-4ft, and we’re back to short-period slop with more of that cross-off wind. There’s one more day, Wednesday the 19th, that has moderate energy at 357 but is again rated as marginal. The wind is offshore, so it might be clean, but the wave quality just isn't forecast to be there.
Honestly, for the next 16 days, there isn't one day I'd tell a beginner to paddle out. The Sunday the 16th is for experienced heads only. For the rest of us, it's a long blank run of poor surf. Keep the board in the car, but the wax in the drawer. Forecasts can change, but as it stands, this is a waiting game.
