The Lowdown
Alright, Rusty again. Let’s break down the Nera Rivermouth situation in feet and miles per hour.
Truth is, it’s a rough 16-day stretch. The Nera Rivermouth is a sheltered, inconsistent river-and-beach spot that needs a solid southwest swell to come alive, and the numbers just aren’t stacking up.
We’re looking at a gap of poor conditions from August 9th all the way through August 24th. There’s a little pulse of energy around August 14th and 15th, with combined swell energy hitting 460 and 484 (moderate wave energy), but the period is short (10 to 11 seconds), and the wind is cross or cross-onshore at 12 to 18 mph. That’s going to be choppy and lumpy. The swell height gets up to 5 feet on the Saturday morning of August 15th, but with that wind and short period, it’s a messy, blown-out mess. This setup honestly looks more interesting for kite surfing than paddle surfing.
The only windows that look clean are the glassy mornings on Tuesday August 11th and Wednesday August 12th, but the swell is tiny – 0.3 feet to 0.7 feet – with combined energy under 40 (weak wave energy). You’d be waiting for a ripple.
There are no standouts here. The best you could do is a very early, very patient longboard session on one of those glassy mornings, but it’s a gamble. The water temperature is about average for the time of year.
The second week doesn’t offer any hope either. By August 20th, the wind is cranking at 28 to 31 mph from the south, and by August 21st, the swell flatlines to zero. A blank run like this is pretty normal for this area.
Rusty.

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.

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.
