The Lowdown
Righto, folks, Rusty here, giving you the lowdown on Barra da Lagoa.
To be straight with you, it’s a quiet outlook for a good stretch. From right now all the way through to the 27th of September, we’re looking at a proper drought. There’s barely anything worth paddling for those ten or eleven days. A few tiny, weak signals but nothing that’ll get you out of bed. That’s a long dry gap, plain and simple.
The one moment that actually has some bite is on Monday the 28th of September in the morning. That’s the one to circle. We’ve got a pulse of swell coming through at 6ft out of the SSE, with combined energy sitting at 354 (moderate wave power). That’s a solid size – too much for beginners, but the right stuff for anyone who knows what they’re doing. The wind is light out of the SW, giving us a clean cross-off breeze. That’s gold for keeping things glassy. The water is sitting at 64°F, which is a little cooler than usual for this time of year, so don’t leave the wetsuit at home.
After that Monday morning, things drop off again quickly. The 29th has some small surf but the quality falls away.
This spot is usually fairly consistent, so having a blank run like this is a bit of an outlier. Forecasts can flip, so don’t lose hope entirely.
