The Lowdown
Alright, Rusty here.
First up, we’re looking at Nera Rivermouth. It’s a sheltered river-and-beach setup that’s beginner-friendly, but don’t get your hopes up too high for this run. The water’s about average temp-wise for this time of year, nothing wild there.
The forecast starts off pretty bleak. Monday the 3rd has a tiny 0.3ft swell from the SW, with a long period of 18 seconds and a moderate cross-off breeze. The combined energy is only 12 – that’s really weak. Not worth paddling out for.
We start seeing a bit of life on Tuesday the 4th. The morning shows 3ft from the SSW, period 19 seconds, and a cross wind at 9 mph. The combined energy is up to 402, which is moderate, but the wind’s not perfect. It’s still a marginal call at best. The afternoon gets a bit bigger but the wind picks up, making it choppy.
Wednesday the 5th is probably the pick of the first week. The morning has 3ft from the SSW with a clean cross-off breeze from the ESE at 9 mph. The energy sits at 291, so it’s moderate but the conditions are clean. The afternoon is similar with lighter wind. For a beginner spot, this is about as good as it gets in this window – small, clean, rideable.
Thursday the 6th drops right back off, and from there it’s a long stretch of poor surf. There’s a gap from Thursday the 6th all the way through to Monday the 17th where the scores are all zeros. There are tiny bumps of swell here and there, like Sunday the 9th morning with glassy conditions but only 2ft and very weak energy (67), so it’s flat and not worth the drive.
We finally get a pulse again on Monday the 17th with 3ft from the SSW, but the wind is cross and the energy is moderate at 342. Still, the forecast calls it poor surf conditions. Not a standout.
The one that catches my eye, and the only real highlight in the whole 16-day run, is Tuesday the 18th. The morning shows 6ft from the SSW, with a period of 11 seconds and a gentle cross breeze at 9 mph. The combined energy jumps to 917 – that’s strong. This is the biggest swell of the period and the conditions are cleaner than anything else we’ve seen. It’s marginal for beginners at that size, but for a stronger intermediate or expert, this is the day to be out there. It’s the only time the wave energy really gets pumping.
Honestly, for Nera Rivermouth, this is a tough outlook. The spot is inconsistent at the best of times, and this forecast shows a long, dry run with only a few windows that are just barely surfable. But that Tuesday the 18th has some real promise – bigger swell, cleaner conditions, and real energy in the water. Keep an eye on it, but don’t hold your breath for the rest.
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.

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.
