The Lowdown
Alright, let’s get into it. This is a tough stretch for Nera Rivermouth. The river-and-beach setup is sheltered from a lot of the main swell directions, and what’s on offer is heavily wind-affected for most of the forecast.
Right now, into Tuesday, we’ve got junk. Cross-shore winds cranking, lumpy chop, and hardly any energy. The first flicker of hope shows up Wednesday morning, the 2nd of September. We get a 6ft SSW groundswell, with a long 15 second period. Combined wave energy hits a strong 1459. The winds are light cross-shore, so it’ll be bumpy but rideable. The swell direction matches the optimum from the southwest, but this spot is inconsistent, so you’ve got to be lucky with the tide and banks.
After that, it drops back into a long, flat, or messy stretch. Thursday the 3rd has some 5ft leftover swell, but the period is still decent at 13 seconds. The wind is cross-onshore, so expect small wind ripples. Not worth paddling out unless you’re desperate.
The real standout is Tuesday morning, the 8th of September. We’ve got glassy conditions — wind is 3 mph from the south, dead calm. Swell is 4ft from the SSW with a very long 14 second period. Combined wave energy is a solid 850, moderate. This is the cleanest window in the whole outlook. The swell direction matches the optimum, and light wind means smooth faces. For a break that’s often inconsistent, this is a rare moment where it could be fun. Because it’s glassy, the crowd factor is likely to be noticeable. It’s a beginner-friendly size too, under 5ft.
After that, it gets grim again. Strong winds choke out the rest of the first week, and into the second week, the pattern is familiar: lumpy cross-shore winds, poor conditions. The next possible highlight comes much later, on Monday morning the 14th of September. Another glassy morning with 3 mph southerly wind — dead clean. Swell is 4ft from the SSW, 17 second period, deep groundswell. Combined energy is 627, moderate. That long period will wrap nicely into the river mouth. It’s a classic early morning session before the seabreeze messes it up, and again, expect some company.
For a spot this sheltered and inconsistent, it’s not been great, but the two glassy mornings – Tuesday the 8th and Monday the 14th – are worth setting the alarm for.

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.
