The Lowdown
Alright, Rusty here. Let's talk about what's on offer at Barra da Lagoa.
We've got a bit of a mixed bag coming up. The real standout window is right at the start. Tuesday morning the 14th of July looks like the pick of the bunch. We're looking at a solid 6ft swell from the SE, with a period of 10 seconds, carrying a good amount of energy (597). The wind is light and offshore from the WSW, which is going to leave the waves clean and peeling. The water temp feels about average for this time of year. This is definitely the session to aim for.
After that, things get messy. The wind swings around and gets onshore or cross-shore for the rest of the week, and the swell drops off fast. From Wednesday the 15th through to Saturday the 19th of July, the conditions are pretty poor for a paddle. The energy drops away (down to the 100s and even 20) and the wind just kills the quality. It’s mostly clean-up sets and choppy conditions, likely more interesting for kite surfing than surfing.
We get a brief, tiny window early Sunday morning the 19th. There's a 4ft swell from the north with clean, light winds, but the swell period is very short at just 5 seconds, and the energy is low (56). It’s surfable but very ordinary.
Then we hit a major gap. From Sunday afternoon on the 19th right through until Wednesday morning the 22nd of July, there is essentially no rideable swell to speak of.
The next glimmer of hope comes late on Thursday the 23rd. We get a glassy 2ft wave from the SE in the afternoon, but again, the energy is low (110) and it's described as very ordinary.
The good news is the consistency of the break itself is fairly decent, so these flat spells can turn around. The rest of the week into the end of July looks very weak with poor conditions from onshore winds, and nothing is recommended for quality surfing until perhaps the morning of Tuesday the 28th, when we get another glassy, clean 3ft wave from the SE, but it’s another very ordinary one.
So, the short version: if you can get out Tuesday morning the 14th of July, do it. That’s the one true standout. The rest of the run is mostly a write-off until the last few days of July, and even then, you're looking at marginal conditions at best.
Rusty.
