The Lowdown
G'day, Rusty here, checking in on the surf outlook for the next couple of weeks. We've got a heap of different options, so let's get into it.
We're looking at a solid run of SSW groundswell, and the standout session is clear. The best wave on offer will be Thursday, September 4th at La Barra (river/jetty). The morning is looking magic with a 4 ft SSW swell, a super long period of 17 seconds and glassy conditions. The wind is dead calm, so it'll be clean as a whistle. The combined energy is strong at 1069, so there's plenty of grunt in the water. This is a solid wave for experienced surfers. The water's sitting at 87°, which is a touch warmer than normal.
The week starts with some small but fun windows. On Tuesday, September 1st, the morning has a 3 ft SSW swell with a 13-second period and a very light cross-onshore wind. The energy is moderate at 348, so it's a bit of a marginal one, but not a write-off. The afternoon gets choppy, so get in early.
Wednesday, September 2nd is a ripper morning. The swell is 2 ft from the SSW with a period of 17 seconds, and it's glassy. The energy is up to 537, so it's a clean, small wave with a lot of push. The afternoon turns into a choppy mess with a strong cross-onshore, so that's a hard pass.
Thursday, September 3rd has a small 2 ft SSW swell in the morning with a very long 19-second period and a light offshore. It's clean and workable, but the afternoon gets messy again.
Now, Friday, September 5th is the other standout. The morning has a 5 ft SSW swell with a 16-second period and glassy conditions. The energy is pumping at 1225, so this is a bigger, punchier wave. The crowds are possible here, so keep your eyes peeled. This one is only for the crew who know what they're doing.
Saturday, September 6th morning is clean with a 4 ft SSW swell and glassy conditions, but the energy has dropped to 700. The afternoons are consistently let down by the cross-onshore wind, so treat them as a no-go.
The following week sees a pattern of clean mornings and messy afternoons. Monday, September 8th has a 3 ft SSW swell, Tuesday, September 9th a 3 ft, and Wednesday, September 10th a 3 ft, all with glassy conditions and decent energy. The long-period swells mean the sets will be clean and well-shaped, but the river mouth setup should handle it fine.
There's a gap of a few days in the middle of the second week where the swell drops right off, with a 1 ft day on Monday, September 14th before it starts to build back up. The pick of the second week looks to be Tuesday, September 15th morning, with a 3 ft SSW swell, 15-second period, and glassy conditions. The energy is a solid 581, so it's worth a paddle.
Keep in mind, the long-range stuff is promising but a bit less certain. The overall pattern is set, but the details might shift. Rusty out.

Information about the La Barra Surf forecast
The above surf forecast table for La Barra provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Barra can be found by selecting the local surf guide option on the grey menu. Our La Barra surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
