Alright, this is Rusty. Let’s talk about what’s happening at Nera Rivermouth.
Right off the bat, I gotta be straight with you – the next two weeks are looking pretty grim for a proper surf session. There’s no real swell on offer for the first few days. Friday the 3rd and Saturday the 4th are flat or near-flat, with just tiny 0.7ft waves and cross winds that aren't doing us any favours. The water temp’s sitting at a mild 75°, which is about normal for this time of year, but that’s small comfort when there’s nothing to ride.
Sunday the 5th and Monday the 6th stay small and messy. We’re talking 0.7ft to 2ft of wind chop, cross-onshore breezes, and the combined wave energy is barely registering – around 236 on Monday morning. Not worth paddling out for.
Now, I do see one window that’ll get your heart racing, but it comes with a warning. On Tuesday the 7th, the swell fires up to a thumping 10ft from the SSW with a very long period of 18 seconds – that’s serious groundswell. The combined energy jumps to a massive 4650, which is strong stuff. But here’s the catch: the wind is cross-onshore at 12 mph, so it’s going to be a choppy, bumpy mess. Plus, Rivermouth is a sheltered, inconsistent spot, and a swell this big with such a long period tends to race straight through at beach breaks and river mouths. The setup looks more interesting for kite surfing than paddle surfing that day. Only experts should even think about it.
Wednesday the 8th hangs in with 8ft to 8ft swell, but the wind stays cross-onshore, and the energy drops a bit to 2553. Still too messy for most. Thursday the 9th drops off to 7ft and is only marginally better, but the chop is relentless.
After that, the rest of the second week is just a slow fade. From the 10th through the 18th of July, we’re back to dribbly little waves – mostly under 3ft, with short periods and cross or cross-onshore winds. There’s a brief moment on the morning of Saturday the 11th with 7ft swell and a cross breeze, which gives it a score of 2 out of 10, but it’s still pretty average with moderate energy at 1197. The morning of Thursday the 16th sees another pulse of 6ft, but again the wind is cross-onshore and it’s not clean.
Truth is, Nera Rivermouth is an inconsistent spot that breaks rarely, and this run is a classic example of a blank period for the area. There are no standouts here. The best bet for a keen surfer would be that Tuesday the 7th big swell, if you’re an expert and don’t mind rough conditions, but for everyone else, save your energy. Forecasts can change, but right now it’s a waiting game.

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.
