The Lowdown

G’day, Rusty here. Look, I’m gonna level with you – the next 16 days at Nera Rivermouth are looking pretty grim for paddle surfing. This spot is a river and beach setup, sheltered from a lot of swell, and it’s inconsistent at the best of times. We’ve got a long stretch of poor conditions ahead, with only a couple of moments that might get your attention, but they come with serious caveats.

The water temperature is sitting at 73°, which is right about average for this time of year, so that’s one thing you don’t have to worry about.

Right off the bat, there’s a gap of several days with nothing worth paddling out for. The first real sniff of anything comes on Sunday morning, the 26th of July, but that afternoon session brings a 8ft SSW swell at 14 seconds. That’s a lot of water moving – combined swell energy is pumping at 2627, which is very strong. Problem is, the wind is cross-shore from the SE at 12 mph, so it’s going to be chopped up and messy. That size is too big for beginners, and with the cross-chop, even experienced surfers will find it tough. Not one to get excited about.

Monday the 27th offers a smaller 6ft to 6ft SSW swell (12-13 second period), with energy in the 818 to 1068 range – moderate to strong. But again, we’ve got a cross wind from the SE at 12 mph. The surf quality is rated as poor, so it’s a pass.

The standout in this whole outlook, if I have to pick one, is Thursday morning the 30th of July. We get a tiny 2ft SSW swell, but the period is a very long 16 seconds, bringing clean, glassy conditions with a light SSW wind at 3 mph. Combined energy is only 215 – weak, so don’t expect any power, but for a beginner-friendly break, it’s the cleanest window we see. The river mouth setup might produce some fun little lines on the low tide banks. Keep expectations low though.

Friday the 31st and into the first weekend of August – forget it. We get a bump in swell to 6ft-7ft on Saturday the 1st of August (SSW, 13-14 seconds, energy over 1294 – strong), but the cross-onshore wind from the SSE at 16 mph makes it a washing machine. That’s more of a kite-surfing setup than a paddle session.

We then hit another gap of almost no surf through the first week of August, with tiny waves and strong cross winds.

The last two potential windows are Thursday the 6th and Friday the 7th of August. On the 6th morning, we get a 2ft SSW swell with a very long 22-second period – that’s deep ocean groundswell. Energy is moderate at 587, and the wind is light from the ESE at 6 mph, giving us clean conditions. That’s promising, but it’s 10 days out, so treat it as a hopeful maybe. Friday the 7th morning is similar: 4ft SSW at 18 seconds, light ESE wind, clean, energy 751. For a river mouth, that long period might make the waves a bit too straight, but if the tide lines up, there could be a fun bank.

Honestly, if you’re desperate, pencil in Thursday the 30th of July morning as the only real glassy offering, or keep an eye on those early August mornings. The rest is a write-off. This spot tends to have long blank runs, so this is pretty normal for the area. Forecasts can change though.

Rusty.

Information about the Nera Rivermouth Surf forecast

The above surf forecast table for Nera Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
