The Lowdown
G’day, I’m Rusty, and reckon I’ve got the local skinny on what’s comin’ our way at Nera Rivermouth. It’s a sheltered river and beach setup, best when a solid SW groundswell lines up with a clean offshore, but it’s an inconsistent little spot that can be real fickle. Right now, we’re lookin’ at a long, quiet stretch before any real hope shows up. Water temp’s sittin’ around 74°F for Tuesday the 14th, which is pretty average for this time of year, so nothin’ to write home about on that front.
First off, Tuesday the 14th and Wednesday the 15th are a complete write-off. We’re talkin’ tiny dribbles of 0.7ft to 1ft from the SSW, with weak wave energy (32 to 141) and poor surf conditions. Light cross-off winds are blowin’, but there just ain’t enough swell to even bother paddlin’ out. Thursday the 16th and Friday the 17th see the swell creep up to 2ft–3ft from the southwest, with moderate energy (218–298) and clean conditions thanks to light offshores. It’s surfable, but very ordinary – you’d be scratchin’ for a ride.
Now, things start to look a bit more interestin’ on Saturday the 18th. The swell pushes to 3ft–4ft from the SSW, with moderate to strong combined wave energy of 497 to 743, and those long-period groundswell lines around 17 seconds will give the waves some real shape and power. Winds are light cross-off, keepin’ it clean. This is the standout session of the whole forecast window – the best on offer. However, because the period is so long, that SSW groundswell might break a bit straight across this beach-and-river break, so you’ll want to pick your peak carefully. That said, Saturday arvo with 4ft of clean, long-period swell is where you wanna be.
Sunday the 19th is a letdown, with the swell droppin’ and wind turnin’ onshore, makin’ for marginal conditions. Then from Monday the 20th right through to the 29th, it’s mostly a mess. We get a solid week or so of poor surf, with strong onshore winds, choppy conditions, and generally weak or junk swell. The 23rd of July even sees a quick spike of 5ft from the SSW, but with a short, weak 10-second period and onshore wind, it’s a sloppy hell of a closeout – only for the brave or the foolish.
There is a glimmer on Tuesday the 28th, with a glassy morning and 2ft from the SSW on a 16-second swell – very clean but tiny. Then Wednesday the 29th arvo brings the last shot: 3ft from the SSW, 13-second period, with moderate energy of 609 and clean conditions from a light cross-off breeze. It’s not a world-beater, but after all that dross, it’ll feel like a gift.
So to sum it up: the real highlight is Saturday the 18th. After that, the forecast turns into a long spell of junk. If you can’t get out on the 18th, keep an eye on the 29th, but that’s a long way off and less certain.

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.
