The Lowdown
G'day, Rusty here. Look, I've had a good look at the Nera Rivermouth forecast, and I'm not gonna lie to you – it's a pretty ordinary run for the next couple of weeks. This spot is a sheltered river-mouth setup, and while it's got that classic river-and-beach feel, it's also inconsistent and exposed to SW swells. The water temp is sitting at 73°, which is about average for this time of year.
The first few days are a write-off. Friday the 28th through to Sunday the 31st of August are all "poor surf conditions" with small, weak swells and messy onshore or cross-shore wind. You're looking at combined energy in the feeble range (156 down to 50), so don't bother.
We finally get a tiny glimmer on Tuesday morning, September 1st. The swell bumps up to 5ft from the SSW with a long 18-second period, and the combined energy kicks up to 1302 (moderate). But it's still cross-shore wind and the call is "marginal." Not great, but it's something.
The real standout – and I mean the only proper standout in this whole outlook – is Wednesday morning, September 2nd. It's the one session that gets a "very good" call. You've got 6ft of SSW groundswell at a solid 14-second period, with light cross-offshore winds from the SE. The combined energy is a strong 1419. That's the morning to chase. It'll be clean and have some proper push, but at that size it's still manageable. The afternoon turns cross-shore and messy again, so get it while it's good.
After that, it's back to the grind. The rest of the first week and into the second is mostly cross-shore wind and small, weak swells. There's a brief mention of offshore wind on Monday morning, September 7th, with 4ft of SSW swell, but it's only rated as "good" conditions, not a standout. Then Tuesday the 8th has a glassy morning with 3ft SSW swell, which would be fun on a longboard, but the energy is low (212).
The second week gets messy. By Wednesday, September 9th, the swell jumps up to 7ft in the morning and 10ft in the afternoon, with combined energy hitting a massive 5255 (very strong). But it's all cross-shore wind and "marginal" at best. Thursday the 10th is even bigger at 10ft with fresh cross-shore wind – that's expert territory and really rough. At that point, with the strong wind and beach setup, this looks more interesting for kite surfing than paddle surfing.
Friday the 11th and Saturday the 12th fade into small, weak junk. Nothing worth paddling out for.
So, to sum it up: the surf is bleak for most of the 16-day window. Your only real chance at a decent wave is Wednesday morning, September 2nd. That's the one. The rest? Save your energy.
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.
