G’day, Rusty here. Look, I’ve been staring at this Nera Rivermouth forecast and it’s a tough one. We’ve got a full 16 days on the table, but honestly, it’s a pretty grim stretch for a paddle. The first week is flat-out quiet, with tiny little waves and poor conditions. There’s a real gap in quality surf here, with nothing worthwhile until the second week, and even then it’s only barely surfable.

Let’s start with the opening days. Thursday the 9th and Friday the 10th of July are a write-off. We’re talking 0.7ft to 1.3ft of swell coming from the SSW, with a period around 18 to 20 seconds. That’s a long-period groundswell, but it’s just too small and the wind is a messy cross-on or cross-shore from the south. The water’s sitting at 74.3°, which is about average for this time of year. The combined energy is weak, just 39 to 146, so there’s nothing to get excited about. The river-mouth setup is sheltered, but it’s not helping here.

Saturday the 11th and Sunday the 12th don’t get much better. Saturday morning sees a tiny 1.6ft SSW swell at 16 seconds, with a light cross-on breeze. The energy bumps up to 147, but it’s still poor. Sunday morning is a bit of a tease—we get a glassy, dead calm morning with a 1.3ft SSW swell at 18 seconds and a decent energy of 231. It’s labelled as “surfable waves but very ordinary conditions.” That’s about the best we’ve got in the first week, but it’s barely a ripple. If you’re desperate, you could go for a longboard session, but I wouldn’t hold your breath.

Monday the 13th through Wednesday the 15th are all poor. The swell stays tiny, between 1.0ft and 2.3ft, with short periods or cross-shore wind messing it up. The energy is all over the place, from 49 to 225, but it’s not translating into any kind of decent wave.

Now, Thursday the 16th of July finally shows a glimmer. We’ve got offshore wind from the ENE at just 3.1 mph in the morning, with a 2.3ft SSW swell at 17 seconds. The energy is 353, which is moderate. It’s clean, and the conditions are “surfable waves but very ordinary.” Still, that offshore wind is a big positive. This is the best of a bad bunch in the first week.

Friday the 17th and Saturday the 18th are the standout days in the entire forecast. Friday morning is glassy with no wind at all, and a 2.3ft SSW swell at 13 seconds. The energy is 245, and it’s clean. Friday afternoon the wind switches to a light offshore from the NNE at 6.2 mph, with a 2.0ft SSW swell at 12 seconds. Saturday morning has a gentle offshore from the NNE at 9.3 mph, with a 1.3ft SSW swell at 14 seconds. Saturday afternoon is the real highlight: glassy, dead calm, with a 3.3ft SSW swell at 13 seconds and a combined energy of 336. That’s a clean, small wave that a beginner could enjoy. The swell direction is SSW, which matches the optimum direction for this break. It’s not big, but with the glassy conditions, it’ll be the best on offer.

Sunday the 19th of July takes a turn for the worse. The swell jumps to 4.3ft to 4.9ft from the SW, but the wind is a strong cross or cross-on from the WNW at 15.5 mph. The energy hits 544 to 626, but it’s choppy and messy. Not worth it.

Monday the 20th of July has a solid 6.2ft SSW swell at 12 seconds in the morning, with a combined energy of 1404—that’s strong. But the wind is a cross-shore from the WNW at 15.5 mph, so it’s lumpy. The afternoon is worse with a fresh cross-on. This is more of a kite-surfing setup than a paddle session, given the strong wind and poor quality.

Tuesday the 21st and Wednesday the 22nd are still poor, with a cross-on wind and dropping swell from 5.6ft down to 2.6ft. The energy is still moderate to weak, but the conditions are choppy.

Thursday the 23rd of July has a 6.2ft WSW swell at 9 seconds, with a gentle cross-shore wind. The energy is 734, but the short period makes it a bit fat and weak.

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.
