The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming up for Barron Rivermouth. This is a point/river setup that likes a solid SW groundswell, and we’ve got that in spades, but the timing and conditions are going to be the real story here.
The water is sitting at a very warm 89° right now, which is much warmer than normal for this time of year. That’s a real talking point.
We’ve got a decent gap before the first real call. The opening sessions on Friday the 28th and Saturday the 29th are a bit of a mixed bag. Friday afternoon has a solid 4ft SW groundswell with a 17-second period – that’s proper long-period energy – but the wind is onshore and the surf is looking poor. The combined energy is moderate (712). Not the one.
Saturday morning the 29th, the swell is up to 4ft from the SW, period 16 seconds, and the energy is strong (1046). The wind is light onshore though, so it’s marginal. But hold on – Saturday afternoon is where it gets interesting. The swell drops to 4ft, but the wind goes glassy, truly offshore from the W at just 3 mph. This is a genuine standout for the week. The wave energy is moderate (671) but the conditions will be clean as a whistle. This is the best session on offer for the first week, for sure.
Sunday the 30th sees the swell drop to 3ft with a 14-second period, but the wind is cross-onshore and the surf quality is poor. Monday the 31st is small, 2ft to 3ft, with a glassy window on Monday afternoon that could be a fun little session for a longboard if you’re desperate.
The first week of September is a bit of a write-off in terms of quality. We get a bit of a bump on Thursday the 3rd of September – 4ft, 18-second period, strong energy (893) – but the wind is cross or light onshore, keeping it marginal. Not worth a special trip.
Now, the real gem is hiding in the second week. Look at the 5th of September – Saturday morning. The swell is 3ft from the SW, a 16-second period, with a light cross-offshore breeze from the N at 3 mph. The energy is moderate (624) and the forecast says “expect very good surf conditions.” This is a solid call.
Then Sunday the 6th of September is a double-header. Morning and afternoon both have 4ft SW swell, 15-second period, and glassy conditions. The energy is moderate (648 and 625). This is clean, consistent, and the best-looking run of the whole outlook. If you can only pick one day, this Sunday is the standout.
The swell tails off after that. Monday the 7th is small. There’s a tiny window of glassy, clean surf on the 10th of September (Thursday morning) with 3ft and a 17-second period, but at that point, it’s a case of making the most of a small clean wave.
Overall, the best bet is Saturday afternoon the 29th of August for the glass and the easy paddle-out, but the absolute standout for quality and consistency is Sunday the 6th of September. Keep an eye on that long-period SW groundswell – it’s got plenty of energy and will wrap in nicely at this point/river break. The crowds can be an issue here sometimes, so get in early.
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. 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.
