The Lowdown
Alright, Rusty here, checking in with the outlook for Barra da Lagoa.
Honestly, this is a tough one. We're looking at a pretty grim stretch ahead. The next two weeks are mostly a write-off for any decent waves. The good news is the water is sitting at a comfortable 66°, which is about average for this time of year, so you won't be freezing your toes off waiting for something that never comes.
The pattern is broken for the first week. From Friday, the 31st of July, right through to the end of the week after, it's a whole lot of flat, tiny, or messy conditions. There's a significant gap where there's basically nothing worthwhile. The swell energy is almost non-existent, with values struggling to hit double digits and often just a zero. Winds are a mixed bag of cross and cross-on, but it doesn't matter when there's no swell to work with.
We do get a little tease on the morning of Friday, the 7th of August. The energy climbs to 92 (moderate) with a 2ft SSE swell and a clean 10-second period, and the wind goes glassy. The report says "surfable waves but very ordinary conditions." It's the best on offer, but that's not saying much. It's a hard pass.
Then, on Saturday, the 15th of August, things get interesting, but not in a good way for most of us. A massive 12ft SSE groundswell with a very long 16-second period shows up. The combined energy is a whopping 6055 (very strong). There's a caveat here: that long-period groundswell can be tricky at a beach break, possibly breaking too straight. But the main issue is that this is way too big for beginners and only for experts. The afternoon session actually gets a note saying "the swell is predicted to be too big for this break." This setup looks more interesting for the kite crowd than paddle surfing.
So, to be blunt, there's nothing to write home about. The one standout, if you can call it that, is the morning of the 7th of August, but it's a real scrap. The massive swell on the 15th of August is a spectacle, but it's a dangerous one. Don't hold your breath.
Rusty.
