The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the coming weeks. I gotta be straight with you – it's a tough stretch ahead. The only spot with any real potential is Nera Rivermouth, and even then, we're looking at a long, quiet gap at the start.

The first hint of anything worth paddling out for doesn't show up until Sunday, September 6th, and it's a marginal one at best. The winds are mostly cross or cross-onshore, which will leave things a bit bumpy and messy. There's a weak-to-moderate combined swell energy (622) hitting that morning, with a 4ft SSW groundswell. It's not going to be a classic, but it's the first pulse we've seen.

After that, we hit another dry spell. The conditions just aren't coming together and there's nothing I'd recommend until we get into the second week. You're looking at a solid few days of coffee sipping on the beach.

Alright, here's the standout. If you're an experienced surfer, circle Sunday, September 13th. That morning, the forecast flips. Nera Rivermouth is looking at a much better picture. We've got a 6ft SSW swell rolling in with a decent period of 15 seconds, giving it some real push and shape. The combined energy is strong (1460). But the big win here is that wind – it's a light, gentle cross-offshore breeze. That means the surface should be clean, with none of that chop we've been dealing with. The swell is over 5ft, so this is for stronger paddlers, not beginners, but for the crew who know what they're doing, this is your window. Expect some crowds though, as this spot can get busy when it's the only game in town.

The rest of the week after that fades quickly. By Monday the 14th, we're back to cross-shore breezes and dropping wave heights. From Tuesday the 15th onward, it's pretty much flat and poor all the way through to the end of the 18th. There's nothing else to chase.

So, to sum it up: the first week is a write-off. Your one real chance is the morning of Sunday, September 13th at Nera Rivermouth. It's a long way out, so keep an eye on it, but if it holds, that's where you'll want to be.

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.

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.
