The Lowdown
G’day, I’m Rusty, and here’s how the next couple of weeks look for the Nera Rivermouth.
Alright, mate, it’s a bit of a slow start here. We’ve got a nice little window on the morning of Monday the 20th of July – that’s the one to get the wetsuit on for early in the week. The swell is coming from the SSW at 4 ft with a very long 18-second period, giving us some proper groundswell energy. The water is sitting at 74°, which is about average for this time of year. The wind is glassy from the SSW at just 3 mph, so the surface is going to be clean as a whistle. The combined energy is moderate, coming in at 732. Just keep in mind, this is a river-and-beach setup that’s sheltered and inconsistent, and it’s a beginner-friendly wave. The swell direction (SSW) matches the ideal SW direction, so it’ll be working well. Crowds are possible here, so don’t sleep in. That morning session is the standout of the first week.
After that Monday morning, it goes quiet. The afternoon turns cross-on with rain showers and a drop to 3 ft, and then from Tuesday the 21st through to the weekend, we’re dealing with a big gap of poor conditions. The surf drops away to nothing, with tiny 1 ft waves and days of zero energy. There’s a fair bit of cross-shore wind, and the combined energy is mostly in the double digits – weak stuff. You’re looking at a solid 5-day lull here.
We start to see a pulse of energy building again on the morning of Sunday the 26th of July. The swell jumps to 5 ft from the SSW at a 17-second period, but the wind is a cross-shore from the SE at 9 mph, which puts a bit of chop on it. The combined energy is strong at 1410, but the conditions are marginal. By the afternoon, it’s up to 7 ft and the energy is 1833, but the cross-shore wind is stronger. This continues into Monday the 27th with 7 ft swell and over 2000 in combined energy, but it’s still a cross-shore wind. This is better for stronger surfers, but it’s not clean.
The real standout of the whole forecast comes on the morning of Sunday the 2nd of August, which is over a week away. The wind goes glassy, absolutely dead calm from the NE, and the swell is a solid 8 ft from the SSW with a 15-second period. The combined energy is very strong at 2479. The water temp anomaly is normal, so no surprises there. This is big, powerful, and clean – but at 8 ft, it’s in the expert-only zone. The afternoon is also glassy from the E at 3 mph with 7 ft swell, so you get a full day of it. That Sunday is the one to circle on the calendar. After that, the wind turns onshore again and the quality drops off into the start of August.
Keep an eye on the morning of Saturday the 1st of August, too – it’s got 8 ft swell from the SSW and a clean cross-off wind from the ESE at 12 mph. Combined energy is 2986, very strong. It’s a solid option for experienced surfers, but the Sunday is cleaner.
So, in short: Monday the 20th morning for a clean, fun beginner wave, and then hold out for Sunday the 2nd of August for the real deal – glassy, powerful, and only for the crew who know what they’re doing.
Rusty.

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.
