The Lowdown
G’day, it’s Rusty here. Let me tell you, the next couple of weeks are looking pretty grim for a wave around here, especially if you’re after that Nera Rivermouth magic. We’ve got a real dry spell on our hands, so don’t be in a hurry to drag your board out.
Right off the bat, this Saturday afternoon is a write-off. We’ve got a fresh cross-shore breeze and lumpy chop, with a weak 3ft SSW swell - a total no-go. The water’s sitting at a normal 73°, so nothing to get excited about there. The next three days just keep the misery going. Sunday’s blown out with a fresh SE wind, and Monday’s tiny, with a long-period swell that’s basically doing nothing. Not a single ride worth paddling for.
Things stay flat and messy through the middle of the week. There’s a bit of a pulse showing Tuesday morning, but it’s still cross-shore and the conditions are just ordinary. Wednesday’s the first time we see a hint of something, with a light cross-off breeze and a clean surface, but the swell is barely a ripple at 3ft. It’s surfable, sure, but only just. You’d be scratching for a wave.
From Thursday up to the following Tuesday, it’s a proper dead zone. Swell heights tumble to under 2ft with short periods, and the wind is either glassy but flat, or light and crossing. There is a little bump of moderate energy (112) on the Tuesday morning, but it comes with a cross-onshore wind, making it choppy and uninviting. Honestly, you’d be better off checking the surf cam from the car.
We then hit a lull that’s almost funny in its emptiness. For days on end, the energy is tiny, often under 50, with only brief, small pulses. The 15th Saturday has a little more grunt in the water (124), but it’s onshore and messy, so it’s not worth your time.
Now, for the far end of the window, there’s a spark of promise. On the 16th of August, we finally see a proper pulse of energy with 570 in the combined reading and a 4ft SSW swell. But, and this is a big but, the period is only 11 seconds and the wind is light cross-shore, so the Rivermouth is going to be lumpy and inconsistent. It’s a marginal call at best, and honestly, for a break this sheltered, it’s not looking like a standout.
So, here’s the bottom line. This river mouth is sheltered and inconsistent at the best of times, but this forecast is a proper blank run. We’re looking at a solid stretch of nothing from now until at least the second week. The energy is so weak for so long that it’s hard to see it turning around quickly. But hey, that’s how it goes sometimes – when it does come back, it’ll be worth the wait. Keep an eye on the charts, but for now, maybe dust off the skateboard.
Rusty.

Information about the Nera Rivermouth Surf forecast
The above surf forecast table for Nera Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Nera 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 (Nera 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 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.
