The Lowdown
Well, folks, it’s Rusty here, and I gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. Let’s get into it.
Right off the bat, we’ve got a long stretch of nothing to get excited about. The first recommendation for a surf doesn’t pop up until late in the game. For the first nine days, from now through to the 17th of August, the surf is essentially flat or blown out. There’s a run of tiny swell with poor conditions, mostly cross-onshore or fresh cross-shore winds that’ll turn the surface into a mess. Nothing worthwhile at all.
The first glimmer of hope arrives on Monday morning, 18th August, at Nera Rivermouth (river and beach). We’ve got a tiny 1ft to 3ft SSW groundswell, but the real win here is the wind. An easterly breeze, just 3 mph, is blowing cross-offshore, making for clean, smooth faces. The combined swell energy is moderate (326) on the morning, so there’s a bit of push, but it’s small and wobbly. The water’s sitting around 73°, which is bang on average for this time of year - no surprises there. This spot is classed as beginner-friendly, but it’s also *inconsistent*, so you’ll be waiting between sets. Crowds are *sometimes* an issue, so you might share it with a few other hopefuls. Honestly, this is the best we’ve got, but it’s still very ordinary.
After that, it’s back to the doldrums. A few days of tiny, weak swell with clean conditions, but nothing that’ll get your heart rate up. The energy drops right off, and then by the 23rd and 24th of August, the swell disappears entirely. A total blank on the charts.
So, if you’re desperate for a splash, try that Monday morning session on the 18th. But otherwise, it’s a waiting game. The forecast can always change, but for now, it’s a bust.
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.
