The Lowdown
G'day, Rusty here. We’ve got a bit of a mixed bag coming our way at Barron Rivermouth. The window kicks off Sunday morning the 26th of July, but to be honest, the whole period looks pretty underwhelming for a proper paddle. There’s a nice-sized, long-period groundswell rolling in early on, but the conditions just won't line up to make it truly worthwhile. The first week is plagued by tricky, marginal conditions with a frustrating amount of cross-onshore breeze, and after that, the swell drops right out into tiny, almost non-existent waves for the second week. It’s a long stretch of poor or marginal surf with only a fleeting glimpse of something clean.
We start Sunday the 26th of July morning with a proper south-west groundswell sitting at 4ft and an impressive 18-second period, wrapping in from the optimum direction. The water temperature is a balmy 89°, a solid 4° warmer than usual for this time of year, so it’s a proper tropical bath. The wind is light and offshore early, but there’s a questionable tide that’s muddling things up, holding the quality back. Combined wave energy is moderate at 961. The afternoon stays similar, around 4ft, but the breeze swings more westerly and cross-onshore, making things pretty choppy. The following morning, Monday the 27th, the swell is still solid at 5ft from the SW, period still a long 18 seconds, and energy is up to a moderate 1287. Yet again, it’s a cross-onshore breeze making it fairly lumpy with small wind ripples. This pattern just keeps repeating itself. Tuesday the 28th of July has the biggest energy reading of the run at 1645 for the morning, with a 5ft, 17-second south-west swell and light offshore wind, but the "marginal surf" label is slapped all over it. The energy is there, around 4 to 5ft through the early part of the week, but with consistent cross-onshore or onshore winds and that long period—which can make a river mouth bar break too straight at times—it’s just never going to be the clean, lined-up day we’re after. The swell fades through Thursday and Friday, dropping to 4ft and then 3ft with increasingly poor conditions. By Friday the 31st of July afternoon, it’s a write-off. The first week is pretty much a bust.
Then we hit a big, flat gap. From Saturday the 1st of August right through to around Friday the 7th of August, the swell is tiny, mostly sitting between 1.0ft and 2ft. The wave energy is weak, dropping down between 43 and 312. The winds are all over the place—cross, cross-on, some storm risks—and it’s just not worth paddling out.
Now, there’s one tiny glimmer on Friday the 7th of August morning. The swell is still only 2ft from the south-west, but with that long 18-second period again, combined energy is a very weak 312. But the magic is in the wind: it’s glassy. A light west-south-west breeze, almost nothing, leaving a mirror-like surface. The forecast says "expect good surf conditions," which is a rare positive in this outlook. The wave quality is rated high, and with the river mouth, those long-period waves might actually find a bit of shape on the bar. If you're desperate for some clean, small-wave practice, that’s your absolute best chance. It’ll be tiny, but it’ll be the cleanest you’ll see. The rest of the month just trails off into poor, tiny, and cruddy conditions again. Honestly, the main event here might be the kiteboarders if they can find enough breeze, because the paddle surfing outlook is flat and bleak.
Rusty.

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.
