The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Barra da Lagoa over the next couple of weeks.

Right off the bat, I’ve gotta be honest with you – the next few days are gonna be a write-off. There’s virtually no energy in the water. Sunday the 6th and Monday the 7th are completely flat, with a fresh southerly breeze making a mess of things anyway. The whole start of the period is a painful gap of dead calm with no surf to speak of.

We finally get a pulse of life on Tuesday morning the 8th. A 4ft SSE swell rolls in with a period of 10 seconds, pushing a decent 382 (moderate energy) into the beach. The wind is light from the NW, blowing cross-offshore, which’ll make for clean, tidy lines. This is a fairly consistent spot, so it’s definitely worth a paddle. The water temp is sitting at 67°F, which is bang on average for this time of year, so no surprises there. That Tuesday morning window is your best bet for the whole forecast – a proper little stand-out session for a beginner-friendly wave.

Things get messy again after that. Wednesday and Thursday see the swell drop right back to ankle-snappers with poor wind and periods of rain, leaving nothing to get excited about. The whole second half of the week is a mix of tiny swell and onshore slop.

Now, looking further out, there’s a bit of a wildcard on Sunday morning the 13th of September. We’ve got a 8ft SSE swell pouring in, with a very strong combined energy reading of 1111. That’s a lot of water moving around. The wind is a moderate S at 12 mph, blowing cross-off, so it’ll be clean. But for a beginner-friendly break, 8ft is getting up there in size, so it’s more for the confident crew. The period is only 10 seconds, so it’s a bit of a short-period windswell, which can be a bit dumpy and tricky on the take-off. It’s a promising pulse, but it’s a long way out so keep an eye on it.

After that, there’s a bit of a lull, then a clean dawn patrol on Tuesday the 15th of September offers a 5ft SE swell with a light southerly cross-off again. The energy is moderate (375), and it’s a solid option for a morning session before the wind swings.

Overall, the first week is a real struggle. The standout is undeniably the Tuesday morning (8th) session. The Sunday the 13th pulse is the one to watch for the second week, but it’s a long-range call, so treat it with a pinch of salt. For now, set your alarm for the 8th.

Rusty.
