The Lowdown

Alright, this is Rusty. Let's break down what’s coming up for La Barra, that point-and-river set-up.

Right off the bat, we've got a quiet spell. The first few days are flat or close to it. Sunday the 30th through Tuesday the 1st are a total write-off with tiny, weak swell and junk wind. Wednesday the 2nd of September shows a flicker of life with a clean 0.7m easterly swell under light offshore winds, but it's small and weak (75-90 energy). Thursday the 3rd is similar, still small but clean with moderate offshore wind pushing the 0.7m to 0.8m easterly swell into something rideable for an intermediate. It's ordinary, not a standout.

Then the pattern gets messy. Friday the 4th and Saturday the 5th see building swell, but the wind swings cross and cross-onshore, turning it into lumpy, poor-quality surf. By Sunday the 6th, a big 3.5m southerly groundswell hits, but it's absolutely shredded by strong cross-onshore winds and rain. That's a mess for paddle surfing, but would be interesting for a kite session.

Now, here's the real standout. Monday the 7th. That morning is the best we're going to see. The swell settles to a solid 3.0m out of the SSE with a very long 16-second period, pumping serious energy (3887). The wind goes glassy—dead calm—which is a massive positive for a spot like La Barra. This is a wave for experienced surfers only, as that size will be too heavy for beginners. The long-period groundswell should set up beautifully along the point and river mouth, offering proper shaped waves. The crowds can be a factor here, so get out early. The afternoon drops in quality, but that Monday morning window is pure gold.

Tuesday the 8th is the second highlight, but a step down. The swell drops to a still-thumping 1.6m from the SSE with a 13-second period, and the morning stays clean with cross-offshore wind. It’s a very good session for stronger intermediates, with solid energy (835). After that, the surf fades through the rest of the week, shrinking back down to 0.6-0.8m by the 10th and 11th with onshore wind returning. The final days from the 12th to the 14th see another pulse of easterly windswell, but the wind is all wrong—cross to cross-on and fresh—so expect lumpy, poor surf to close out the period.

So, to sum it up: the first week is a bust, but the second week has one true gem. If you’re an experienced surfer, make a plan for Monday the 7th. Otherwise, Tuesday the 8th is your best bet for cleaner, more manageable waves. After that, it’s a slow fade.

Rusty.

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. If you surf the same spot (La Barra) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
