The Lowdown

Alright, let’s have a look at what’s on offer.

Alright, let’s look at Nera Rivermouth. This is a sheltered river-and-beach setup, and it’s an inconsistent spot that rarely fires, so when it does, you’ve got to pay attention. The water temp is about average for this time of year, nothing wild there.

The week starts quiet. Tuesday the 25th has a little pulse of 4ft SSW swell, long period around 15 seconds – that’s proper groundswell. The morning sees a light cross-off breeze, and the combined energy is moderate at 746. It’s clean, but the wave comment says “good surf conditions” for a beginner-friendly wave. It’s not going to blow your mind, but it’s a fun little wave for a learner. The afternoon gets a bit bumpier with a moderate breeze, and the score drops right off.

Wednesday the 26th is similar, a touch smaller at 4ft, still that long-period SSW swell. Morning has that light cross-off again, clean, with moderate energy of 491. Again, not a standout, but a nice little session for the right crew. The afternoon gets cross and choppy.

Now, Thursday the 27th morning – this is where it gets interesting. The swell drops to 3ft, but the wind goes glassy. That’s a huge positive. The combined energy is 413, still moderate, but the conditions are glassy. That’s a rare treat at this break. The swell is long period, 15 seconds, so it’ll be a bit walled on a beach break, but at a river mouth, it could wrap in nicely. This is probably the best window in the first few days.

Friday the 28th and Saturday the 29th are a write-off. Swell is tiny, wind is onshore or cross-onshore, and the energy is weak. Sunday the 30th has a spike to 5ft, but the wind is howling onshore at 16 mph, so it’s a mess. That trend continues through to Monday the 1st of September. The afternoon of the 1st has a big energy reading of 1133 from a 4ft, 19-second swell, but the wind is cross and moderate, and the wave comment says “marginal.” Not worth paddling out for.

Now, here’s the real standout. Wednesday the 2nd of September morning. The swell jumps to 7ft from the SSW, with a period of 16 seconds. That’s a solid groundswell. The combined energy is 2485 – that’s strong. The wind is light and cross-offshore, so the face is clean. This is excellent surf, but only for experienced surfers. That’s a big wave for a river mouth, and it’s going to be powerful. The afternoon drops a bit but still has good energy.

After that, the swell fades fast. Thursday the 3rd through to the 6th is mostly small, weak, and messy. The 8th of September afternoon sees a return to 3ft SSW swell, 18-second period, clean conditions with a light cross-off, and energy of 507 – that’s a good call for a smaller board, but it’s not a standout.

The last big one is Wednesday the 9th of September morning. Swell 6ft, 16 seconds, cross-off light breeze, energy 2232. That’s another clean, powerful swell for the experienced crew. It’s a week and a half away, so keep an eye on it, but it’s promising.

So, the best on offer is the morning of Thursday the 27th of August for the glassy conditions and a fun little wave, and then the morning of Wednesday the 2nd of September for the bigger, cleaner, groundswell for the experts. The 9th of September is a promising long-range option but less certain.

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.
