The Lowdown

G’day, Rusty here. Let’s look at what’s coming up for Barron Rivermouth. This is a point/river setup, gets exposed to the swell and breaks fairly consistently, but it can get a bit busy sometimes. First thing – the water’s at 32°F – no wait, we’re doing imperial now – 89°F, which is way warmer than normal for this time of year, over two degrees above average, so that’s a standout.

We’re in a slow period to begin. Thursday the 27th and Friday the 28th have small swell but the wind’s messy, cross-onshore, and the surf quality is poor. Not worth getting wet for.

Saturday morning the 29th shows some life: 5ft of SW swell with a 16-second period, light onshore wind, and a big energy reading (999). The forecast says it’s marginal – likely tricky tide or a bit fat – but there’s a chance for a good wave if you’re on it. Afternoon goes bad with stronger wind.

Sunday the 30th keeps that SW swell around 3-4ft, period dropping to 14 seconds. Morning has light cross-shore wind, energy is solid (687). Still a marginal call but cleaner than the previous days.

The real standout is around Friday the 4th of September. That’s the one to circle. Friday morning we’ve got glassy conditions with 4ft of SW swell, a 17-second period, and energy at 843. The afternoon turns offshore with NE wind, and it stays clean. Saturday the 5th follows up with offshore ENE wind in the morning and glassy in the afternoon, same 3ft of SW groundswell. Clean, well-shaped waves, good energy. That’s the best stretch on offer.

Sunday the 6th and Monday the 7th are smaller and cleaner – 2-3ft with good wind, cross-offshore and glassy at times – but the energy drops off (409-341). Fine for a small-board or longboard cruise.

After a windy patch Monday afternoon, things heat up again around Thursday the 11th of September. That morning shows 7ft of SW swell with a 14-second period and energy over 1800 (1864). That’s strong, but the wind is cross-shore and it’s called marginal – could be rugged. For experts only.

For beginners, nothing tops 5ft until that 7ft pulse, which is too big. The good days on the 4th and 5th are around 3-4ft – clean and manageable.

Crowds are sometimes a thing here, so the standout days might have a few others out.

Bottom line: Friday 4th and Saturday 5th September are the pick – glassy to offshore, good SW groundswell, clean lines. Get in the water.

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.
