Updates in hr min s Forecast update imminent
G’day, Rusty here. Let’s be honest, the next couple of weeks are a tough watch for us at Barra da Lagoa. We’re staring down a long dry spell before anything half-decent shows up.
Right now, it’s flat and quiet. The water’s sitting at 62°F, which feels much colder than normal for this time of year – a good three to five degrees below what we’d expect, so you’ll want a thick steamer. The first real pulse of energy doesn’t arrive until Sunday, July 6th, when a moderate SSE swell shows up at 6ft but with a pretty ordinary period and messy winds from the NNE. That marks the start of what looks like a week of mediocre, forgettable surf. The combined wave energy will be up and down, hitting moderate levels like 705 on that Sunday afternoon and 528 on Monday morning, but the conditions are just never there to back it up. Winds stay cross or onshore for most of that week, and the swell direction (SSE to SE) isn’t doing us any favours.
After a week of that, we finally get a standout. Mark your calendar for the morning of Sunday, July 12th. That’s when we’ve got a clean, glassy morning with 3ft of ESE groundswell pushing in at a nice 12-second period. The combined energy climbs to a solid 548, and with that glassy surface the waves should be clean and lined up. This is the best on offer – nothing else comes close. The swell direction is hitting our optimum from the ENE, so the banks should handle it nicely. It’s a beginner-friendly spot, so it won’t be too heavy, but expect crowds because this is the one morning everyone will be keen on.
The following Monday morning, July 13th, is also worth a paddle. Clean cross-off winds, 3ft of SSE swell at 11 seconds, and 411 combined energy. Not a standout, but a solid, fun session after the Sunday buzz.
From there the energy fades fast. By mid-week we’re back to small, weak stuff – combined energy dropping into double digits by July 17th and 18th, with onshore winds and rain. The last few days of the outlook are best saved for a beach walk. There’s really nothing worth chasing in that final stretch.
