The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on offer for the next couple of weeks.
First up, the honest truth: the whole 16-day window is looking pretty bleak for a proper surf. Picao (Baia Formosa) is our only option, and it’s just not happening. The swell is there, but it’s short-period, weak energy, and the wind is ruining any chance of quality. The water’s sitting at a warm 80.8°, which is about normal for this time of year.
We kick off Tuesday, August 25th, with a 4.9ft swell from the east, but it’s a weak 7-second period and the wind is a cross-offshore breeze at 19 mph. The wave energy is a measly (260) – it’s all just a bit of a mess. That "poor surf conditions" tag is spot on. This same pattern holds through the rest of the week and into the next. Swell hovers between 3.9ft and 4.9ft, all from the east or east-southeast, with periods between 7 and 8 seconds. The wind is mostly cross or cross-offshore, but it’s just not enough to clean up the weak, short-period chop. The combined energy rarely breaks past 300, staying in the moderate range at best, but the quality is just not there.
The only slight glimmer, and I mean *slight*, comes around the morning of Monday, September 7th, and Tuesday, September 8th. We see a clean, cross-offshore wind from the southeast at 16 mph, and the swell picks up to 4.6ft to 4.9ft from the east. The period is still short (7 seconds) and the energy is still nothing special (249), but the wind is cleaner. Then on Wednesday, September 9th, the period finally bumps up to 8 seconds and the energy hits 295, but the wind is back to cross-shore with a chop. It’s still a "poor surf conditions" call.
Honestly, there’s no standout session here. The wind is never truly offshore, the swell is weak and short, and the break is a reef setup that needs a proper push. For a beginner, the 4.9ft days might be a bit much, but the quality is so poor it’s not really a worry. This is a tough run. Forecasts can change, but right now, I’d say leave the board at home and go for a swim.
