The Lowdown
Righto, grab a seat. Rusty here, and I’ve been staring at the charts for this little corner of the world. It’s a quiet stretch we’ve got on our hands, so don’t go expecting a pumping session any time soon.
Look, if you’re hanging out for a wave, you’re gonna need a lot of patience. The whole 16-day window is a tough one. Nera Rivermouth is the only spot we can talk about, and to be honest, even the "good" days are pretty ordinary. Let’s not sugarcoat it.
The first week is a write-off for any kind of surfing you’d want to paddle into. From Thursday the 13th right through to Monday the 17th of August, it’s all cross-shore to cross-onshore winds with a messy, lumpy sea state. Swell is there, but it’s useless with that wind. On Sunday the 16th and Monday the 17th, there’s some longer-period energy – 16 seconds – and the combined energy gets up there, hitting 657 and even 902 on the Monday. But with fresh cross-shore winds blowing at 19 mph to 22 mph, it’s a choppy, blown-out mess. That’s more of a kiteboarding gig than a paddle surf session.
Things look a tiny bit better by Tuesday the 18th of August. We get a morning session with a cross-offshore breeze (light, at 9 mph), and the water cleans up. The swell is a small 4 ft from the SSW with a long 15-second period, and the combined energy is moderate at 498. It’s surfable, but it’s hardly a standout. The waves will be weak and the sets inconsistent – this break is temperamental at the best of times. Still, if you’re desperate for a splash and you’re a beginner, it’s your best shot of the fortnight. Water temp is sitting at 73°F, which is about normal for this time of year, so a spring suit will be fine.
After that, it drops right off. Wednesday the 19th has a few similar tiny, clean waves, but by Thursday the 20th, the swell just dies. From Thursday the 20th of August all the way through to the end of the outlook on Friday the 28th of August, it’s a long, flat run. We’re talking waves that are lucky to reach 1.0 ft, and the combined energy is often under 100. There is a tiny kick on Wednesday the 26th with some short-period 3 ft swell, but it’s cross-shore and weak.
So, the honest truth: there’s nothing to get excited about. The one brief window on Tuesday the 18th is the only time the stars almost align. If you’ve got a log and a lot of patience, paddle out then for a few crumbly little runners. Otherwise, save your energy. Forecasts can change, but this run looks stubborn.
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.
