The Lowdown

Alright folks, Rusty here. Let’s have a look at what Nera Rivermouth has got cooking for us over the next couple of weeks.

Straight up, it’s a pretty bleak run for the most part. We’ve got a long quiet spell from now all the way through to the end of August and into the first days of September. The wind is constantly onshore or cross-shore, the surf is tiny or junk, and you’ll be staring at a whole lot of nothing for days. There’s a big gap of poor, flat conditions that stretches right through the first week of the forecast.

We do finally see a flicker of life on Wednesday the 2nd of September, but you’ll have to wait for it. The only real standout in this whole 16-day window is the Wednesday morning session. We’ve got a south-southwest swell coming through at a solid 7ft, and the period is a long 14 seconds – real groundswell energy. The combined energy is pumping hard at 1591, so there's plenty of punch. The wind is a light cross-offshore breeze from the east-southeast, which is going to clean things up nicely. This is a river and beach setup, and with that long period, it will likely hold up better than a standard beach break, so shape should be there. It’s going to be big though, over 5ft, so this is for the experienced crew. Beginners, sit this one out. The swell is from the SSW, which matches the optimum direction for this spot. Expect crowds, it’s a small river break and word will get out for a morning like this.

Wednesday afternoon sees the wind swing cross-shore and the energy drop, so it’s a short-lived window.

After that, the rest of the forecast is a letdown. There are a few mornings with a bit of swell and cleaner conditions – like the 10th and 11th of September – but the energy is weak to moderate (384 and 424) and the swell height is small, around the 3ft mark. It might be surfable, but you won't be writing home about it. The 8th of September morning has a big 7ft SSW swell, but the wind is cross-onshore and it’s rated as poor, so it’ll be a messy, choppy mess – more of a kite surfing day than a paddle session.

The water temperature here is about average for this time of year, nothing crazy to report.

So, to wrap it up: the only day worth chasing is Wednesday the 2nd of September, early. Get out there if you can handle the size, otherwise, it’s a waiting game for the next proper groundswell.

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.
