Rio Pro, 2025
June 21st - 29th

All times are local.
Australia is 13 hours ahead: 9pm Saturday here is 8am Saturday in Rio.

Once again, we’ve got a quick turnaround between CT stops. There's just five days between Trestles and Brazil, with the waiting period for the Vivo Rio Pro set to kick off this Saturday, running through until the following Sunday.

However, we’re unlikely to see competition get underway this weekend thanks to the lack of any notable swell. Saquarema will be small out of the east on Saturday and then a touch bigger from the south on both Sunday and Monday.

With just three days needed for competition, the WSL can afford to be picky so they'll have their sights on the middle to end of the waiting period, which looks much more active. That corresponds with the middle to end of next week when a series of strong frontal systems spawn off the Argentinian coast, spinning around a large, slow moving Southern Ocean gyre.

Each of these frontal systems will generate moderate to large pulses of south-southwesterly swell from Wednesday through Friday, easing a little into the weekend.

The first will generate an expansive fetch of south-west gales that will push up towards southern Brazil through Monday, with the swell due to build into Tuesday afternoon albeit with onshore winds. Wednesday looks a better option with wave size peaking around 6 foot, replete with light variable winds ahead of afternoon sea breezes.

A secondary, reinforcing pulse of south-southwest groundswell is due on Thursday to 4-6 foot, generated by further strong to gale-force south-west winds off Argentina. Again, local winds at Saquarema look great through the morning, offshore out of the north-northeast, before strengthening out of the east into the afternoon.

Friday appears similar with light early winds giving way to sea breezes and the swell easing further. Those three days - Wednesday, Thursday, Friday - will likely be the three likely competition days.

If, however, any of those days fails to deliver the WSL has a contingency plan with a secondary surge of gales due later next week. They'll produce a less consistent though moderate-sized south-southwest groundswell for next weekend. At this point, size appears to peak around 4-6 feet on Sunday, though winds are too hard to decipher. With the storm staying at arm's length from Brazil, the inclination is to think we'll have favourable morning conditions, though we’ll have a closer look at the exact timings and sizes of the incoming swell pulses in the next update.
