The Lowdown

G’day, Rusty here.

Look, I’ll be straight with you – this outlook is a tough one. There’s not a single day in the next 16 days where I’d tell you to grab your board and head down to Nera Rivermouth with any real hope. The whole window is a write-off for decent surf. We’ve got a long stretch of poor conditions with no real standouts to get excited about. It’s a bit of a blank run, to be honest.

We start off on Thursday, August 13th, with a tiny bit of swell, but it’s poor. The morning has a light offshore breeze with a 2ft swell from the SW at 10 seconds – not much energy here (130). By the afternoon, the swell bumps up to 3ft from the SW with a 13-second period, and the energy picks up a bit (270), but the wind swings onshore, ruining any chance of a clean wave. The water temperature is sitting at 73°, which is about normal for this time of year.

Friday the 14th and Saturday the 15th see a little more size, with 3ft to 4ft swells from the SSW, but the wind is a cross-onshore or cross-shore breeze, making everything choppy and lumpy. The energy values are moderate (343 to 428), but the conditions are just messy. Sunday the 16th brings a long-period 16-second swell from the SSW, hitting 3ft, and the energy spikes right up to 606 (moderate-to-strong), but again, the cross-wind chops it all up. That long-period groundswell would be better suited to a point or reef, but here at this river-and-beach break, it’s just going to close out or be a washing machine.

The following week doesn’t get any better. From Monday the 17th through to Wednesday the 26th, we see a mix of tiny swells, flat spells, and strong winds. The energy is weak, with values often below 100, and the few pulses of swell are either too small or have poor wind direction. Even a rare glassy day on Friday, August 21st, with a slight air and a 0.7ft swell, is just too small to do anything with. The water temp anomaly is neutral, so no surprises there.

The very end of the window, on Friday, August 28th, shows a tiny 1ft, 18-second period swell from the SSW with 122 energy, but with a light cross-shore breeze, it’s still not going to produce anything rideable.

This spot is ‘inconsistent’ and ‘sheltered’ from the SW swell, and the conditions just aren’t lining up. It’s a rare period where there’s genuinely nothing to recommend. Sometimes that’s the reality of this area.

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.
