The Lowdown
Alright, Rusty here again. Let’s break this down in feet and knots, same story.
We’re staring at a long, 16-day stretch that’s mostly a dud. Barron Rivermouth is the only spot on the menu, and the first week is tough. Swell’s small and the wind is messy. You’ll need patience, but there are a couple of moments that might make it worth the wait.
Tuesday 21 July is a skip. We’ve got a 3ft SW swell with a very long 15-second period, and the morning has a light offshore from the WSW at 6 knots. But the notes say “poor surf conditions.” That long period groundswell is going to want to run straight at this river mouth anyway. Water temp is 89°, which is a touch warmer than normal for this time of year, but don’t get your hopes up for the waves.
Wednesday 22 July and Thursday 23 July are more of the same. Some waist-high SW swell, but the wind is cross-onshore or onshore, making it lumpy and unrideable. The energy on Wednesday morning is moderate, but with a cross-on breeze, it’s chopped up.
Friday 24 July afternoon – here’s our first real glimmer. After days of junk, the wind flips to a light offshore from the ENE at 3 knots, going glassy. The wave is tiny, only 2ft, but the period is a massive 23 seconds. The energy reading is moderate. For a point/river mouth, that long period groundswell can wrap in and produce a clean, tiny line. This is your first chance for a smooth, groomed wave, but you’ll need a longboard or a log.
Saturday 25 July and Sunday 26 July see the swell hit 4ft, but the wind turns onshore (WSW), so it’ll be choppy and ugly. Hard pass.
Now, the real standout. Monday 27 July morning. The swell is 5ft from the SW at 18 seconds – proper, long period groundswell. The wind is light and cross-shore from the S at 6 knots. For Barron Rivermouth, that’s as clean as it gets. The combined energy is strong at 1406. This is the best chance for a real, rippable wave in the first week. It’s not huge, but it’s clean and has punch. If you’ve only got one session, make it this one.
Tuesday 28 July and Wednesday 29 July bring bigger surf – 6ft – but the wind is cross-onshore. At 6ft, it’s getting into expert territory and will be a handful in those conditions. The energy is very high, but the quality is poor.
Thursday 30 July morning is a minor mention. The swell drops to 5ft from the WSW at 14 seconds, with a light onshore wind. It’s marginal, but better than what’s around it.
After that, from Friday 31 July onward, it really dries up. The swell fades to under 3ft, and the wind stays onshore or cross-onshore until Wednesday 5 August. There’s a 5-day gap with nothing worth chasing.
One last tiny glimmer at the very end – Wednesday 5 August morning. The wind goes glassy, dead calm, with a 3ft WSW swell at 10 seconds (short period). The energy is weak. It’ll be clean, but it’s small and weak. Bring the biggest board you own.
So, here’s the take: The best surf in this whole run is Monday 27 July morning for a clean 5ft SW groundswell. Second pick is Friday 24 July afternoon for a small, glassy, long-period wave if you just need a clean ride. Everything else is a waste of energy.
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.
