The Lowdown
Alright folks, Rusty here, taking a look at the local stretch for the next couple of weeks.
Right off the bat, I gotta be honest with you – we’ve got a pretty flat and messy start ahead. The waves are small and the wind is just not playing ball for the first few days. We’re looking at a long stretch of middling to poor conditions from the very beginning. The water here is sitting at 68° at the start, which is pretty much spot on for this time of year, so at least the paddle won't be a shock to the system.
What we are really waiting for is a late surge of energy that shows up in the second week. The first real glimmer of hope comes on the morning of Sunday, the 6th of September. The swell is a modest 4ft from the NW, but the wind is a light cross-off from the SSE, cleaning things up nicely. The combined energy is moderate (438), and it’s the first time we get a proper window of clean conditions. It’s not huge, but it’s a start.
The real standout, the one you want to circle on the calendar, is the morning of Tuesday, the 15th of September. This is the best we’ve got. We’re looking at a solid 7ft of groundswell rolling in from the WNW, with a period of 13 seconds. That’s proper energy, and the combined swell energy is a massive 1471, so you’ll feel the power. The kicker is the wind: it’s glassy, coming from the ESE, which is going to make it incredibly clean. This is a session for the experienced crew though – at 7ft, it’s a bit too much for beginners, but for the rest of us, it’s going to be pumping. The break is Praia da Barra, a sandbar, and it’s exposed to the west, so that WNW swell will be hitting it well.
The morning of Monday, the 14th of September, is also worth a mention. It’s a much smaller wave, only 1ft, but the wind is light and clean from the NNE, and the swell period is a very long 19 seconds. That’s a super long-period groundswell, which will be best for the points and reefs, but at a beach break like this, it might break a little too straight. The energy is still moderate (292), so it’s a fun wave for the loggers.
For the rest of the period, it’s a real mixed bag. The afternoons are consistently blown out by a stiff NW breeze, and the wave heights are generally too small or too messy to get excited about. The long-period swell on the 5th of September Saturday morning is a tease, but it's only 3ft.
So, bottom line: the first week is a right-off for the most part. The second week has some promise, with the 15th of September being the clear winner. Be patient, and you’ll be rewarded.
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.
