The Lowdown
Alright, Rusty here, checking in with the local surf outlook for the Barron Rivermouth. Let's get into it.
Alright, we’ve got a bit of a mixed bag over the next couple of weeks. The pattern is mostly small, but there are a few windows where the stars align. The water is sitting at a balmy 89° today, which is a touch warmer than usual for this time of year, so you might not need a full suit.
The first real standout is Monday afternoon, August 3rd. We’re looking at a clean, glassy 2ft swell from the southwest. The wind is almost nothing at 3 mph, making it perfect for a late session. The combined energy is moderate (182), and with that 13-second period, the waves will have some decent shape. This is the pick of the first week.
After that, things get messy. We have a long stretch of onshore and cross-onshore winds from Tuesday, August 4th, through to the morning of Saturday, August 8th, with swell dropping to 1.0ft to 2ft. It’s poor surf conditions, so save your energy.
Saturday afternoon, August 8th, brings a shift. The wind goes cross-offshore from the north at 6 mph, cleaning things up nicely. The swell picks up to 3ft from the southwest, with a 16-second period. The combined energy is strong (404), and the report says to expect good surf. This is another solid window, but you’ll want to be aware of the risk of thunderstorms.
The following week is a bit of a grind. We see a lot of onshore wind and marginal conditions. The swell stays small, mostly between 2ft and 3ft, and the energy fluctuates. The morning of Friday, August 14th offers a glimmer of hope with a 3ft, 18-second period swell from the southwest and a cross-shore southerly breeze, giving a combined energy of 631. That’s strong energy, but it’s a bit of a wildcard.
The real potential for the second week lands on Sunday morning, August 16th. The wind is cross-offshore from the north at 6 mph, which will keep the 3ft southwest swell clean. The combined energy is moderate (266), and the report says to expect good surf. It’s a long-range call, so keep an eye on the forecasts, but it’s promising.
The Barron Rivermouth is a point and river break that’s fairly consistent and exposed to the southwest swell, which is right on the money for these swells. It can get crowded sometimes, so get in early if you can. This is a break for intermediate surfers; the swell is small, so it’s fine for all levels, but watch for the longer period swells on the 8th and 14th, which could make things a bit more challenging.
To sum it up: Monday afternoon, August 3rd is your best bet for a clean, fun session.
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.
