The Lowdown
Alright, let’s get this sorted. It’s Rusty here.
To be honest, the next week and a half is a bit of a write-off. We’ve got a lot of junky, wind-blown swell and not much quality. But hold on, there’s a glimmer of light at the end of the tunnel. Keep your eyes on the end of August and the very start of September.
Now, let's break it down day by day.
Starting from Tuesday the 18th, it’s messy. We’ve got a 5ft SSE windswell with a short 6-second period and a fresh 22 mph onshore breeze. The energy is weak (169), and it’s just poor. Nothing to get excited about.
Wednesday the 19th, the swell drops right off. We’re looking at a weak 2ft S swell, still with a short period and light onshore winds. The energy is really weak (65). Keep the board in the car, mate.
Thursday the 20th, it gets even smaller. 1ft S swell with light rain and light cross-shore wind. Combined energy is a pathetic 29, just weak. Not a chance.
Friday the 21st, the wind pipes up again. A fresh 22 mph S cross-onshore breeze blows straight into a 5ft S swell. It’s lumpy, it’s poor, and the energy is still moderate (174). Not worth the paddle out.
Saturday the 22nd sees the swell come up a bit, hitting 6-7ft from the SSW, but the wind is still a fresh 22 mph cross-shore. The energy is getting stronger (450-660), but the conditions are just too messy. This one’s for the experts only, and even then, it looks challenging.
Sunday the 23rd, the swell clean-up starts, but it’s not there yet. We’ve got 6ft SSW/S groundswell, but the wind remains an issue. The energy is now strong (1037), but the surface is lumpy and cross-onshore. Marginal at best.
Monday the 24th, now we’re talking. This is the standout. The wind finally eases off and goes cross-offshore from the NE at just 3 mph. The swell is a solid 6ft from the SSE with a 13-second period. The energy is strong (1156) and the forecast says “excellent surf conditions.” This is going to be clean and powerful at La Barra (Estuary). It’s a river mouth, so this long-period groundswell should really focus. This is our best bet of the whole stretch. Get on it.
Tuesday the 25th is a step down. The swell drops to 3-4ft, still from the SSE with a long 11-second period. The wind goes cross-offshore again in the morning, making it clean, but the energy has dropped back to moderate (265). It’s surfable, but not the same as Monday.
Wednesday the 26th and Thursday the 27th are pretty average. Small, weak swell with light winds. The energy is weak. Not much happening.
Friday the 28th, the morning is small but clean, but the afternoon sees the swell pick up slightly to 4ft from the SSW with a short 6-second period. The wind is cross-offshore and the energy is moderate (260). Could be a sneaky fun one but nothing special.
Saturday the 29th and Sunday the 30th are pretty poor again. Small, weak swell and the wind swings onshore. No good.
Monday the 31st and Tuesday the 1st, the wind becomes a major issue. Tuesday the 1st of September has a strong 28 mph cross-shore wind, making it a complete mess despite the 3-4ft SSE swell. Kite surfers might dig it, but surfers, stay home.
Finally, Wednesday the 2nd of September. Another one to watch. The wind goes light and cross-offshore from the NNE, with a 3ft SSE groundswell rolling in with a 12-second period. The energy is moderate (314) and the forecast says to “expect good surf conditions.” It’s a much smaller version of that Monday the 24th swell, but should be clean. A promising end to the run, but less certain being further out.
So, for the standouts, it’s Monday the 24th for the main event, and then Wednesday the 2nd of September as the backup.
Alright, I’m signing off.
Stay stoked,
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.
