The Lowdown
G'day, Rusty here. Let's have a look at what's on the table for Barron Rivermouth over the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a slow start. There's really nothing worth paddling out for until we get into the first week of September. The first few days are all poor surf conditions with cross-onshore winds messing things up, and the swell is just too weak and short to get excited about. You're looking at a solid week of pretty much nothing.
Come the morning of Thursday the 3rd of September though, things start to look a bit more interesting. We've got a clean 3ft SW swell rolling in with a very long 18-second period. That's proper groundswell energy, and the water's glassy with a light cross-onshore breeze. The combined energy is up at 838 (moderate wave energy). It's still only a marginal call, but it's the first real sign of life.
The standout window is shaping up for the afternoon of Thursday the 3rd of September. The swell bumps to 4ft from the SW, with a 19-second period – that's a long-period groundswell that'll wrap into the river mouth nicely. Winds go light offshore from the WSW, which is exactly what you want for a clean face. The combined energy hits 1032 (strong wave energy). For a point break like Barron Rivermouth, that long period is a bonus – it'll hold shape and push through nicely. It's not for beginners though, with the size pushing past 3ft. Crowds can be a problem here sometimes, so don't expect to have it to yourself.
The Friday morning of the 4th of September keeps the swell going at 4ft from the SW, 17-second period, and the combined energy is even higher at 1127 (strong wave energy). The wind is light cross-shore, so it should be clean enough. Again, that's a solid size for intermediates and up.
After that, the swell hangs around in the 3ft to 4ft range but the periods drop off a bit, and the winds get a little more onshore or cross-onshore. It's still marginal but a lot better than that first week. The long-range stuff is promising, but you know how it is – don't lock in your plans just yet.
The water temp is a warm 89°F, which is much warmer than normal for this time of year – a solid 4°F above the average. You won't need a wetsuit, that's for sure.
So, if you're keen, pencil in that Thursday afternoon of the 3rd of September and the Friday morning of the 4th of September. That's the best of the lot. Everything before that is a write-off.
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. 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.
