The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Nera Rivermouth. Gotta be straight with you – this is a rough stretch. The forecast is a long, frustrating gap where the surf just isn't on. We're looking at Friday the 31st of July for a tiny window, and then pretty much nothing worth paddling for until the middle of the next week.
The only real starting point is Friday morning, July 31st. The river mouth is seeing a small 3 ft swell from the SSW, but the real story is the wind. It’s glassy, dead calm from the NW at just 3 mph. For this spot, that’s pure magic. The wave energy is moderate (236), and the water is sitting at 73°, which is bang on average for the time of year. It’s a beginner-friendly wave, so if you’re learning, this is your moment. The swell direction isn’t exactly the optimum SW, but with that glassy surface, you’ll take it. Just be aware that this spot is inconsistent and can get crowded sometimes.
But don’t get too excited. That Friday morning window is it. By Friday afternoon, a cross-onshore wind from the south at 9 mph messes it up, and the surf drops to 2 ft. Then from Saturday the 1st of August right through to about Tuesday the 11th of August, the stars just don’t align. The wind is either howling from the SSE at 19 mph, making it lumpy and cross, or the swell disappears entirely. There are days with zero combined energy. It’s a proper dead zone for over a week.
There’s a tiny flicker of hope on Tuesday morning, August 4th, with a 3 ft SSW swell and clean cross-offshore winds from the ESE. The energy is moderate (406), but the score is low. It’s marginal. The period is a long 19 seconds, which is a groundswell. At a river mouth, that long period might make it break a bit too straight, but it’s clean, and you might snag a few if you’re desperate.
Wednesday the 5th of August and Friday the 7th of August also offer some clean, small waves around 3 ft, but the energy is lower. Saturday the 8th of August has a glassy 3 ft swell, but it’s still just ordinary. None of these are standouts.
Look, I’ll be honest: the best on offer is that Friday morning, July 31st, for the glassy conditions. After that, it’s a waiting game. For a spot that’s often inconsistent, this kind of blank run is more normal than not. If you’re a kite surfer, the strong cross-shore winds on the weekend might be more interesting than paddle surfing. But for now, stay tuned – forecasts can change.
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.
