The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Barra da Lagoa.
Honestly, the next week and a half is a tough slog. We’ve got a good run of moderate wave energy coming through, but the wind and conditions just aren’t lining up for a proper surf. The water’s sitting at 65°F, which is about average for this time of year, so nothing weird there.
Thursday the 27th kicks off with a pulse of 6ft swell from the SSE with a long 14-second period, and the combined energy is strong at 1156. That’s a proper groundswell. But the morning wind is a light cross NNW breeze, so it’s messy. By the afternoon, wind swings N-NE and chops it right up. This swell is better suited for a point or reef than a beach break anyway.
Friday the 28th drops to 3ft, and it’s blown out by moderate cross-onshore winds. Saturday and Sunday are tiny – under 2ft – and definitely not worth paddling out for.
There’s a long gap of flat or close-to-flat days from Sunday the 30th through to Wednesday the 4th of September. The combined energy is in single digits, and it’s just dead.
Things try to come back to life on Thursday the 5th of September. We see a 3ft SSE groundswell with a 11-second period, and the energy picks up to 354. But it’s cross-onshore again with a moderate N breeze, so you’re fighting chop. Not a standout by any stretch.
If you’re holding out for something clean, the only real window is Sunday morning the 7th of September. The swell is small, only 2ft from the SSE, but the wind is light S, cross-offshore, and it’s clean. The combined energy is weak at 68, so it’s more of a longboard or a foamie session. Still, it’s the cleanest you’ll see in this whole period.
The best on offer? Honestly, there isn’t a proper standout here. None of these days line up with good swell, clean wind, and decent size. The 6ft pulse on Thursday the 27th had potential, but the wind ruined it. The 4ft SSE swell on Friday the 11th of September has a nice 14-second period and clean cross-offshore wind in the morning, with solid energy at 640, but it’s a long way off and the tide may be questionable. That’s the one to watch, but keep your expectations low.
This is a period where forecasts can shift, but right now, it looks like a whole lot of waiting and watching.
Stay patient,
Rusty
