The Lowdown
Alright, Rusty here. Let’s look at what’s cookin’ for the only break in town.
So, we’re stuck looking at Nera Rivermouth. It’s a sheltered river and beach break, and it’s inconsistent, so don’t expect waves every day. It’s good for beginners when there’s something, and it needs a southwest swell to work.
Man, the first week is a write-off. From Saturday the 12th all the way through the end of the week, the conditions are just ugly. The wind is the main culprit. We’ve got a fresh breeze from the southeast kicking up a lumpy cross-chop nearly every day, and the tide is messing with what little swell there is. Saturday the 12th morning has a 8ft SSW swell, but with a 19 mph cross-shore wind, it’s just a bumpy, choppy mess. Not worth the effort. That repeats for Sunday the 13th through Friday the 18th. There’s some solid energy in the water, especially Monday the 14th morning (moderate wave energy at 1588) and Friday the 18th morning (strong energy at 1935), but the wind stays cross or cross-onshore, ruining any chance of a clean face.
But hold up. Look at Saturday the 26th afternoon. The wind finally plays nice and goes cross-offshore from the ESE at 16 mph. That’s a huge positive, keeping the surface glassy. We’ve got a 4ft SSW groundswell with a very long 21-second period, delivering strong energy (1384). That long period means the waves will have plenty of power and form, but at a river/beach break like this, it can sometimes make the waves jack up and close out. Still, with clean conditions, it’s the only standout in the whole run. Friday the 25th morning gives a little window with a light 9 mph cross-shore and a 3ft SSW swell (moderate energy at 435), but it’s only marginal. Saturday the 26th afternoon is the one to pencil in.
Water temp is about average for the time of year, so no need for a thick wetsuit.
This is a rough stretch for the Nera. The swell shows up, but with the wind and tide against us for so long, it’s looking more like a kite-surfing session than a paddle session for most of the fortnight. But forecasts can always change, and that last Saturday is a real glimmer of hope. Keep the fingers crossed.

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.

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.
