The Lowdown
Right, surfers, Rusty here. We've got a long look ahead at Praia da Barra and to be honest, the opening act is a bit of a dud.
The first good surf doesn't show up until the morning of Friday the 28th of August. Before that, we're looking at nearly three days of poor conditions with onshore winds and weak, messy waves. Wednesday the 26th and Thursday the 27th are a write-off with stormy weather and choppy slop, so don't even bother.
But then, Friday morning the 28th is the big prize in this forecast. A clean, glassy morning with a solid 8ft swell from the WNW. The combined energy is strong (1277), and with a period of 11 seconds, those are proper groundswell lines. That size is for experienced surfers only – it's a powerful wave. The offshore gets a bit messy in the afternoon, so get on it early.
Saturday the 29th and Sunday the 30th drop right off. We're back to small, weak waves and onshore wind. A bit of a letdown after that Friday flash.
Monday the 31st and Tuesday the 1st of September see the size pick back up to around 6ft to 7ft from the NW, but the wind is cross-shore and lumpy all day. It's not totally worthless, but it's a long way from clean.
After that, the whole first week of September looks like a near-total blank. Day after day of small, weak, wind-affected surf. The 6th of September has a glimmer of a long period (12 seconds) swell, but it's tiny and the wind is howling.
The real standout, however, is the morning of September 8th. This is a monster call for the far end of the window. Swell hits 13ft from the WNW, with a very long 14-second period and enormous wave energy (6214). This is big, powerful, and heavy – strictly for experts. The morning wind is light, so it could be the session of the month. The afternoon turns onshore again, so again, it's a dawn patrol mission.
Praia da Barra is a sandbar setup that rarely breaks, so any good surf is a treat. The water temperature feels about average for this time of year.
Overall, you've got one epic Friday morning (August 28th) and a promise of a massive, expert-only swell on September 8th. The rest is either small, windy, or just plain poor.
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 Praia da 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.
