The Lowdown
G’day, Rusty here. Look, I’ll be straight with you—this is a tough one. The whole 16-day window for Nera Rivermouth is a real bust. There’s nothing on offer for ages, and honestly, the forecast is grim. We’ve got a long stretch of poor surf, with cross-onshore and cross-shore winds messing things up, and the swell is either tiny or just plain ugly. The first few days are a total write-off from Saturday the 29th of August right through to the end of the first week. The conditions are choppy and crummy, and the combined energy readings are weak to moderate at best, with values like 569 (moderate) on Saturday morning, but the wind is all wrong.
Water temp is sitting at 73°F with a 0.7°F anomaly, so pretty average for this time of year. Nothin’ special there.
We don’t see anything worth a paddle until Monday the 7th of September. That morning, you’ll get a bit of a break—a glassy, clean session with a 2ft SSW swell, period of 19 seconds, and a combined energy of 393 (moderate). That’s a long-period groundswell, which means the waves will have some shape and energy, but this is a river and beach break, so it might break a bit straight. Still, glassy conditions are a major positive, so you could get a couple of fun ones. But don’t expect crowds—this spot is inconsistent and only for beginners, so it’s not gonna be pumping.
Then, look ahead to Friday the 11th of September. The morning shows some promise with a 3ft SSW swell, 19-second period again, and a clean cross-offshore wind. The energy is 621 (moderate to strong), and the forecast says “expect good surf conditions.” That’s the standout window. The swell direction is SW, which is the optimum for this spot, and the wind is clean. It’s not huge, but it’ll be tidy. Saturday the 12th of September morning and afternoon are also looking solid—clean winds, 3ft to 4ft SSW swell, and period around 16-17 seconds, with energy readings of 572 and 765 (moderate to strong). That’s your best bet for the whole forecast. Just remember, this spot is inconsistent, so it’s a rare event when it comes together.
After that, Sunday the 13th of September goes flat again. So, if you’re keen, pencil in the 11th and 12th of September. The rest is a washout.
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 Nera 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.
