The Lowdown
Alright folks, Rusty here. Let's have a look at what Nera Rivermouth has in store for us over the next couple of weeks. Gotta be straight with you, this one's a tough stretch.
We're looking at a long, dry gap at the start. The first sign of anything remotely surfable isn't until Thursday the 3rd of September, and even then, it's a bit of a struggle. The water temp is sitting at 73°, which feels about normal for this time of year, so no surprises there.
The opening act on Thursday morning sees a 5ft SSW swell rolling in with a 13-second period. The combined swell energy is moderate at 703, but the wind is a light cross-onshore from the south. It's not terrible, but it's not clean either. The report calls it marginal, and honestly, it's a tough one to get excited about for a beginner-friendly spot. The afternoon goes flat with a 0 score.
Friday the 4th through to Wednesday the 16th is pretty much a write-off. There's a bit of swell on Sunday the 6th – a 5ft SSW swell in the morning with moderate energy (926) – but the wind is still putting a ripple on it. We get a bigger pulse on Saturday the 12th with a 10ft SSW swell and very strong energy (6139), but that's a major size for a river-mouth spot, and the wind is a messy fresh cross-shore. That's big, lumpy, and only for experts at best. For the most part, we see small, weak swells or onshore chop. There’s a brief spike to 6ft on Friday the 11th, but again, the wind just kills it.
The light at the end of the tunnel comes on Thursday the 17th of September. Finally, the wind shifts to a light cross-offshore from the ESE, cleaning things right up. We get a 3ft SSW groundswell in the morning (moderate energy at 445) and a smaller, clean 2ft SSW swell in the afternoon. The report even says "expect good surf conditions." For a break that's inconsistent at the best of times, this is the pick of the bunch. The wind will be clean, and it'll be a decent wave for a beginner at the river mouth. Crowds are possible here, but with the conditions we've had, it might be quiet enough.
Friday the 18th also looks rideable with a clean offshore wind from the NE, but only small 2ft SSW swell. It's surfable, but nothing special compared to the day before.
So, the standout is Thursday the 17th of September at Nera Rivermouth. It's the only time in the whole 16 days where everything lines up for a proper, clean session on a small but manageable swell from the SSW. It’s not a huge day, but after the long dry spell, it'll feel like a gift.
Stay patient.
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.
