The Lowdown
Alright folks, Rusty here. Let’s be real – this is a tough outlook for Barra da Lagoa. The next couple of weeks are looking pretty grim for surf, with a big stretch of flat or poor conditions. The water temp is about average for this time of year, so no surprises there at least.
The first real shot of surf shows up on the morning of Thursday, July 24. It’s our best bet by a long shot. We’ve got a 6ft swell from the SSE, period around 9 seconds, and combined energy reading moderate (493). The wind is light from the south, making it clean. That’s a solid, fun-sized wave for the more experienced surfers – 6ft is a bit much for beginners. The swell direction comes from the SSE, which is a bit off the optimum ENE, but with that clean texture, it’ll still be rideable. Afternoon glass-off conditions with a 5ft SSE swell and glassy wind will be a dream. Crowds are likely here often, so expect company.
Saturday, July 26, holds a smaller 5ft SE swell with a short 8-second period in the morning. Clean again with light winds, but the energy drops to moderate (291). The afternoon gets a bit messier with a cross-shore breeze, making it only marginal.
Then we hit a long dry spell. From Sunday, July 27, all the way through the end of the window on August 5, it’s mostly poor or flat. You’ll see very small leftover swells, weak energy (values like 139, 82, 40), and most days have onshore or cross-onshore winds chopping it up. There’s a tiny pulse of 3ft on August 1 with a long 11-second period, but the wind is onshore, ruining any chance of quality. By the start of August, it’s back to flat with no swell showing.
So, the standout is Thursday, July 24. That’s your window. Everything else is a write-off.
Rusty.
