The Lowdown
Alright folks, ol' Rusty here, lookin' at the charts for the next couple of weeks. It's a bit of a mixed bag, gotta be honest with ya. We've got some serious grunt coming through at times, but the wind gods aren't always gonna play nice. Let's start with the pick of the litter.
The standout window looks to be that Sunday morning, the 24th of August. La Barra (Uruguay) is gonna be the place to be. We're looking at a solid 6ft swell out of the S with a juicy 12-second period, and the wind is gonna be a gentle cross-offshore breeze. That's a recipe for some proper clean waves, the kind that make you forget about the work week. The combined energy is up there at 959, so there's some real push in the water. This thing is gonna have some shape. Now, because it’s a long-period groundswell, it might be a little straight-breaking at a beach, but for a point and river mouth like La Barra, it’s gonna be threading nicely. Just bear in mind, crowds can pop up here, so get there early.
Before that, there's a lot of wind to deal with. We've got a strong, lumpy cross-shore on the Friday the 14th and Saturday the 15th. Sunday the 16th morning cleans up with a NNW offshore breeze and 4ft from the east, but it’s not the biggest. Monday and Tuesday the 17th and 18th are pretty ordinary. Then things get messy again through the 19th and 20th, although the 20th has a tiny 2ft wave with clean offshore wind. Nothing to get excited about.
Now, into the second week, there’s potential. That Sunday the 24th is the real standout. The Monday the 25th is back to being choppy and onshore. But then, look at the 27th and 28th of August. Early mornings on the 27th (Thursday) and 28th (Friday) are showing light offshore and cross-offshore winds with 4ft and 3ft swell. The energy is moderate (210 and 208), but it’ll be clean. Those are your quiet, fun-sized sessions for the end of the run. The rest of that last week is mostly onshore slop.
All in all, pencil in the morning of the 24th as the best call. If you can't wait, that Sunday the 16th morning is your best early bet, and keep an eye on the 27th and 28th for a clean, smaller paddle.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for La Barra may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
