Alright, Rusty here, let’s size up what’s on the menu for Barra da Lagoa over the next couple of weeks.
Right off the bat, the water is sitting at 62°F, which is a solid 5°F colder than what you’d normally expect for this time of year. That’s a real chill, so a thick wetsuit is a must.
The outlook starts slow. We’ve got a run of small, weak energy through until Wednesday morning, July 8th, with combined energies hanging in the moderate range. The surf is rideable but nothing special. The best of these earlier days is Wednesday the 8th, when we get a glassy 3ft swell from the ESE with a period of 9 seconds. It’s small, but perfectly clean under a light WNW breeze.
The real standout is Friday morning, July 10th. We get a clean 3ft swell from the ESE with an 11-second period. The combined energy is moderate, and the wind is a light cross-off from the SSW. It’s not a huge day, but the conditions will be clean and fun for a beginner-friendly wave. For a more experienced surfer, Saturday the 11th has a punchier 5ft ESE swell with a 13-second period, but it’s a tricky morning with cross-shore winds making for a bumpy surface.
The best quality is shaping up for the second week, but it’s a bit further out so take it with a grain of salt. Keep an eye on Sunday the 12th. The morning has a clean 4ft ESE swell with a 12-second period, but it’s the afternoon where it gets interesting—a solid 7ft SSE swell rolls in with strong combined energy. The wind stays clean cross-off from the south. That’s proper groundswell, so expect some nice shape, but it’s pushing into big-wave territory, so it’s one for the experts only.
After that, the swell backs off but we get a few more clean mornings. Wednesday the 15th has a nice 3ft SE swell with a 14-second period under a light cross-off. Clean, lined up, and much more manageable.
This spot can be inconsistent, but it’s fairly consistent here. Even when it’s small, the glassy mornings save the day. Crowds are something to think about at Barra da Lagoa—it gets “often” busy, so get in early.
Rusty.
