Alright, this is Rusty. Let me break down what’s on the horizon here.
I gotta level with you – the next week and a half is going to be a grind. There’s a consistent, long-period SW groundswell running through the whole 16-day window at Barron Rivermouth, but the wind just won’t cooperate for most of it. The forecast is full of "poor surf conditions", so you’ll need to be patient and pick your window.
The swell energy builds into a strong range, peaking at (1002) on Tuesday the 7th, with a very long 18-second period and waves up to 4ft. But the wind that afternoon is a light cross-onshore, keeping things messy and marginal. The water is also running hot – 87°F, which is 4°F above normal for July. It’s going to feel like you’re paddling in a bathtub.
For the cleanest session, you’ve got to wait it out. Monday morning the 6th offers a bit of hope with light winds and a 3ft SW swell, but it’s still cross-onshore. The real gem is much further out, on Tuesday the 14th. That morning, the winds go dead calm – glassy conditions. The swell is small, just 2ft from the SW with a 13-second interval, but with zero wind, that river mouth setup will be as smooth as glass. The energy is light (222), but for pure quality, that’s your best bet. It’ll be clean, fun, and uncrowded.
Outside of that, most afternoons are blown out by onshore breezes. The swell energy is moderate to strong, but without clean wind, Barron Rivermouth is going to be a bumpy mess. You won’t have to fight for waves, though – the lineup will be quiet.
The last day on the 17th shows a new SSW pulse building with a better period, but the winds are still all wrong. Might set up for something better just after this window closes.
It’s a long wait for one glassy Tuesday morning. That’s your shot. I’ll be there.

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. Our Barron Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Barron Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
