Table - best surf conditions forecast for Nera Rivermouth over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s on offer for the Nera Rivermouth over the next couple of weeks. I’ll be straight with you – it’s a quiet stretch, so keep your expectations in check. We’re looking at a spot that’s inconsistent and sheltered, with the optimum swell from the SW. The first bit of anything surfable doesn’t show up until Monday morning, July 13th, and even then it’s tiny.
The week starts off with a real whisper. On Monday morning, July 13th, we get a clean, glassy 1ft swell from the SW, with a very long period of 14 seconds. The wind is light and cross-offshore from the ESE at 3 mph, which is lovely for the surface. But the energy is weak (50), and the wave comment is flat out ‘poor’. It’s a fun little fizzle for a log, but nothing to get excited about. The water is sitting at a warm 74°, about average for this time of year. Monday afternoon turns a bit choppy with a cross-shore breeze kicking up.
Tuesday the 14th starts even smaller, 0.7ft, but the afternoon brings a pulse of 4ft from the SE, though with a short period of just 6 seconds. That’s windswell, and the energy is still low (111). The wind stays light and cross-offshore so the surface is clean, but the wave quality is poor. It’s just not doing much.
Wednesday the 15th sees tiny surf again, with a bit more energy in the water (110–126) but the heights are 1ft to 2ft. The cross-offshore wind in the morning gives way to a cross-shore breeze in the afternoon that messes with the shape.
Thursday the 16th is the first time the energy kicks up a notch – we see moderate energy (410) from a SSW swell at 3ft, with a solid 16-second period. But the wind turns cross-onshore from the SSE at 6–9 mph, putting a bit of chop on it. The quality is still poor. Friday the 17th is similar, with 3ft to 5ft of SSW swell and moderate to strong combined energy (384–555), but the wind stays cross-onshore or cross-shore. Friday afternoon is the first time we get a ‘marginal’ reading, but it’s still not worth the paddle.
Saturday the 18th has a similar story – 5ft SSW swell with moderate to strong energy (507–591), but the wind is cross-onshore and the morning is marred by light rain. Still poor conditions overall.
Sunday the 19th is interesting. The morning is still marginal with a 2ft SSW swell, but the period is a massive 21 seconds – that's a proper groundswell with very long lines. The wind is light cross-onshore, so not ideal. Sunday afternoon, though, sees the energy spike to 1113 – that’s strong wave energy – with a 3ft SSW swell at a 20-second period. And the wind goes straight onshore from the SSW at 6 mph. The wave comment is still only ‘marginal’, but that’s the best we get in the whole run. That deep groundswell is holding together despite the wind. It’s a river mouth setup, so that long-period stuff can get a bit weird on the banks, but for a patient soul on a bigger board, there might be a few.
After that, it trails off. Monday the 20th and Tuesday the 21st see dropping swell (3ft to 3ft) with moderate energy but cross-onshore winds that are picking up to 12–16 mph, making it choppy and poor. Wednesday the 22nd and Thursday the 23rd are even smaller, with Thursday seeing zero energy.
Then we hit a blank patch. From Thursday afternoon, July 23rd, through to the end of the forecast on July 28th, there is no surfable recommendation at all. The energy drops to zero for a couple of days, then we see tiny 0.7ft to 1.0ft waves with very weak energy (18–72). Friday the 24th morning is glassy and calm, but there’s nothing to ride. Tuesday the 28th has a glassy morning with 0.7ft and a 15-second period, but it’s just a ripple.
So the standout here, and the only true highlight, is Sunday afternoon, July 19th. At Nera Rivermouth, you’ve got 3ft of SSW groundswell with a 20-second period and strong wave energy (1113). The wind is onshore, which is a shame, but that energy is real. It’s a long-range hope, so keep an eye on the forecast. For the rest of this 16-day window, it’s mostly a skunk. With the inconsistent nature of this spot, a blank run is pretty normal. Still, forecasts can change.
Stay patient.

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.
