The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s heading our way. We’ve got a 16-day window, and honestly, it’s a bit of a slow burn. There’s nothing firing straight away, so we’ll need to be patient. The first real chance for a wave comes up on Saturday morning, the 8th of August, but it’s a rough one to start.
The overall pattern is small, long-period SW groundswell, but with a lot of messy wind days in between. The wave energy is moderate, sitting around 446 (moderate) on Saturday morning, but it drops and climbs through the week. The standout window is actually a fair way off, on the 22nd of August, but we’ll get to that.
Saturday morning, 8th August is a write-off for a paddle. You’ve got 3ft of SW swell at 16 seconds, but a cross-onshore wind from the S at 9 mph makes it choppy. The energy is there (446) but the surface is junk. The afternoon cleans up a bit with a NE cross-off, but it’s still not great.
Sunday, 9th August is the first real glimmer. The morning is all glass. Swell is 2ft from the SW, period 14 seconds, and the wind is dead calm from the SSW at 3 mph. The energy is 264 (moderate), but that glassy surface is a major positive. It’ll be clean, but small. The afternoon gets a bit bumpy with a cross-on.
The best chance in the near term falls on Saturday morning, 22nd of August. That’s your pick of the whole outlook. The swell is still modest at 3ft from the SW, period 14 seconds, but the wind is a dead calm from the NNW at 0 mph. It’s glassy. The energy is 266 (moderate). For a point/river setup like Barron Rivermouth, that long-period SW groundswell is perfect. It’ll bend into the river mouth and offer up some nicely shaped, clean lines. The wave energy is moderate, but the conditions will be pristine. Just keep in mind crowds are possible here, as it’s a break that gets people.
The rest of the fortnight is a mix of marginal conditions and poor surf. The wind is mostly cross-on or onshore, especially from the WNW, which ruins the surface. The swell never really gets over 4ft, and the periods are long (14-19 seconds), which is good for shape but means longer waits between sets. The energy sits in the moderate range (200-693) for most of it, but the wind is the killer.
For the experts, there’s nothing here that’s too big. It’s all under 5ft, so it’s fine for most levels. The long period (over 15 seconds at times) will make the waves stand up nicely at the point, but it’s not a powerful, pushy swell.
In summary: the first week is a wash. The second week has a few marginal mornings, but Saturday the 22nd is the one to circle. Glassy, clean, small but fun. That’s your best bet.
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.

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.
