The Lowdown
Alright, this is Rusty.
Honestly mate, I’ve been staring at the charts for Barron Rivermouth and it’s a tough stretch. We’re looking at a pretty bleak run of surf for the first week and a half. The southwest swell is hanging around, but the conditions are just all over the place. There’s a big gap from now until the start of the second week where you’d be hard-pressed to find a proper wave.
For the immediate future, Friday the 31st of July through to the weekend, it’s mostly poor surf. The swell is small, around 2ft to 3ft, but the wind is messy—cross-onshore or onshore, making it choppy and uninviting. The wave energy is weak to moderate, but it’s just not coming together. You’ll be fighting wind and chop more than riding waves.
We get a slight reprieve on Tuesday the 4th of August. Early morning the wind goes glassy, dead calm, and the swell is a tiny 1ft from the southwest with a long 16-second period. The energy is weak, and the report says "surfable but very ordinary". It’s gutless, but it’s the cleanest we’ll see for a while. That’s about as good as it gets in this first week.
From Wednesday the 5th up to the 10th of August, it’s a real dead zone. The swell drops to 1.0ft to 1ft, energy is low, and the wind keeps shifting around. You’ll be staring at a flat ocean more often than not. A few sessions have a "marginal" tag, but nothing worth paddling out for.
Now, things finally show a glimmer of life on Tuesday the 11th of August. That’s the standout. The morning session is looking like the best of the entire 16-day window. The swell is still small at 2ft from the southwest, but it’s a long-period groundswell at 18 seconds, pushing moderate energy. The wind is from the southeast, blowing cleanly offshore and creating good conditions. For a point/river break like this, that long period will actually wrap in nicely and give you a proper, lined-up wave. It’s a small wave, but it’ll be clean and rideable. The break is fairly consistent, so you can expect a few waves. Keep in mind, crowds are possible here sometimes.
After that, Wednesday the 12th sees a bump in swell to 3ft and more energy, but the wind turns onshore and ruins it. There’s another marginal window on Thursday the 13th and Friday the 14th, but the wind is cross-on or onshore again, killing the quality. The best bet is that Tuesday morning, the 11th of August. It’s not a classic, but it’s the only real window of clean surf.
Rusty.

Information about the Barron Rivermouth Surf forecast
The above surf forecast table for Barron Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barron Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Barron Rivermouth 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 (Barron Rivermouth) 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 Barron Rivermouth 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.
