The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this stretch ain’t gonna have you ringing your mates to get out of work. We’ve got a 16-day window, but it’s a real flat, ordinary run for the most part. There’s no standout swell, no magic window, just a few moments where you might get a soggy little wave if you’re desperate. The first real sniff of anything surfable isn’t until Thursday the 30th of July, and even then it’s nothing to write home about.
Let’s start with the only spot on the cards: Nera Rivermouth (river and beach). It’s a sheltered, beginner-friendly wave that’s inconsistent, so you gotta be patient. The water temp is about average for the time of year, nothing unusual.
Thursday morning the 30th of July brings a tiny 1ft SSW swell with a very long period of 16 seconds, but combined energy is weak (102). Wind is a light cross-off, so it’s clean, but the wave comment says “poor surf conditions.” That’s a polite way of saying it’s barely breaking. Afternoon picks up a fraction to 2ft, 15-second period, energy 169, still “very ordinary.” You might get a couple of straight little runners on the river mouth, but it’s a real struggle.
Friday the 31st of July is the best we’ve got across the whole 16 days, and it’s still only a 1 out of 10. Morning offers 3ft SSW swell, 14-second period, with energy at 236 (moderate). The wind is dead glassy – S at 3 mph. That’s a major positive; the surface will be like a mirror. The wave comment says “surfable waves but very ordinary conditions,” which for this spot is about as good as it gets. It’s small, slow, and for a beginner, those glassy conditions might make it worth a paddle. Expect crowds sometimes, but honestly, with this quality, it’ll be quiet. Afternoon turns to a cross-shore breeze and the quality drops right off.
Saturday the 1st of August is a write-off. Rain showers, 16 mph cross-on wind, choppy, 3ft but messy. Not worth a look.
Then we hit a real dead zone. From Sunday the 2nd of August through to Wednesday the 5th of August, there’s either no swell or barely a ripple (energy below 100), and the wind is nasty cross or cross-on. You’re looking at a gap of several days with nothing to recommend.
Thursday the 6th of August morning offers a tiny 2ft, 14-second swell, energy 135, light cross-off, clean – but it’s so small it’s barely a ripple. Again, “very ordinary.”
After that, it’s a long stretch of poor surf. From the 6th of August afternoon through to the 14th of August, nearly every session is labelled “poor surf conditions.” The swell tries to push a little higher around the 8th and 9th of August, with 4ft SSW swell, but it’s onshore, short period (8-10 seconds), and choppy. That 4ft is too big for beginners anyway, and with the wind, it’s junk. The combined energy in that period is moderate (around 300-350), but with poor wind and a beach/river setup, it’s more interesting for kite surfing than paddle surfing.
Late in the window, around the 14th of August, you get a tiny 0.7ft, 21-second period swell from the SSW, but the energy is only 46, and it’s cross-on. It’s a whisper.
So, to sum it up: the only real chance to get wet is Friday morning the 31st of July at Nera Rivermouth. It’s small, but glassy, and for a beginner who just wants to feel a glide, it’s your best bet. Don’t hold your breath for the rest. Forecasts can change, but right now, this is a blank run that’s pretty normal for this sheltered spot.
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. If you surf the same spot (Nera Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
