Alright folks, Rusty here. I've been staring at the charts for Nera Rivermouth, and I'm not gonna sugarcoat it – it's a rough outlook. This is a sheltered river and beach break that likes its swell from the southwest, and we're in for a long, quiet stretch.

Start with the water, it's running about normal for the season at Nera Rivermouth, so no surprises there.

We are looking at a huge gap with no real surf. From Saturday the 11th of July right through to Tuesday the 14th of July, it's flat or close to it. Tiny waves of 1 to 2 feet with cross or onshore breezes. On Monday the 13th, it's glassy, but the swell is a pathetic 1ft from the SW. Just nothing to work with.

Wednesday the 15th of July morning shows a pulse. A 2ft swell from the SSW, with a nice long 13-second period, and a light offshore wind keeping it clean. Wave energy is moderate at 163. It's surfable, but only just. You might get a few little peelers.

Thursday the 16th is similar size but the cross-breeze starts to put a bump on it.

Now, Friday the 17th of July brings some real size – 6ft from the SW, with a 12-second period. That's a 880 reading (strong wave energy), but the wind is cross-onshore and the description says marginal. That's big, expert-level surf, but blown out. Saturday the 18th of July is 5ft and onshore. Honestly, for a paddle surfer, this looks worse than the small stuff. Kite surfers might be all over it.

We then hit another dry hole. From Sunday the 19th of July through to Thursday the 23rd of July, it's back to tiny, weak swell. Sunday the 19th has a 2ft swell with a 20-second period, but at a beach break, that long period just means it will close out. Not worth the drive.

Into the second week, there's a tiny glimmer on Friday the 24th of July morning. Glassy conditions, a 2ft SSW swell, 13-second period, moderate energy at 194. It says "surfable but ordinary". You could get a clean little ride, but don't expect anything epic.

The only one that gets my pulse up a little is Saturday the 25th of July. The morning shows a 6ft SSW swell with a 17-second period. The wave energy is 1534 (very strong wave energy), and the wind is light cross-onshore. That is a serious, long-period groundswell. At Nera Rivermouth, that could set up nicely on the river mouth if the banks are good, but that cross-onshore wind is a major caveat. It's flagged as marginal. This is the biggest, most powerful swell of the whole 16 days, but it's a gamble on the wind.

So, the short of it: no true standouts. You've got a couple of clean but tiny days on the 15th and 24th, and a potentially big but dicey day on the 25th. It's a lean period. Keep your eye on the 25th, but don't book the day off work just yet.

Rusty.

A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu.

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.
