The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Barra da Lagoa.
To be honest, the next week and a half is a bit of a write-off for any decent paddle surfing. The water temp is sitting right around average for this time of year at 66°F, but the surf just isn’t showing up. We’ve got a long stretch of tiny, weak swells with poor energy readings, and the wind is mainly cross or onshore, keeping things messy. The best we see in the early days is a couple of glassy moments on Wednesday the 5th and Thursday the 6th, but the swell is tiny – 0.7ft to 2ft at best – so it’s not really worth paddling out for. Don’t get your hopes up for any of the weekend or early next week swells either; they’re mostly flat or junk.
Now, hold onto your board, because there is one standout window that looks like the real deal. On Tuesday morning, August 11th, the stars align. We’re looking at a solid 8ft groundswell rolling in from the SSE with a very long period of 15 seconds. That’s proper energy – the combined energy reading is a massive 2627, which is a serious pulse of power. The wind is a light offshore from the SSW, which will keep the waves clean. This is big, powerful, and long-period stuff though, so it’s going to be a handful. At this size, it’s not for beginners, and the long period will make it peel fast and hollow, best suited for the more experienced crew. The wave direction is ENE, and this swell is coming from the SSE, so it might not be a perfect match for the break, but with that much energy and clean conditions, there will be some bombs.
After that, we fade back into mediocrity. The following Saturday morning, August 15th, has a clean 4ft SSE swell, but the winds turn onshore in the afternoon, messing it up. The waves are there, but the window is tight. The Sunday morning of the 16th sees a 6ft swell with a short 8-second period, which is a bit of a mushy mess, though it’s clean with offshore winds.
So, the bottom line: wait for that Tuesday morning, the 11th. That’s your best, and really only, standout for the whole 16 days. Everything else is a flat spell or not worth the paddle.
Rusty.
