The Lowdown

Alright, Rusty here. Let’s have a look at what we’ve got.

Honestly, the story around here for the next couple of weeks is a bit of a bummer. The break on offer is Nera Rivermouth, and while it can be a fun little river-and-beach setup, it’s inconsistent and sheltered from the main energy. The water temp is sitting at 74°, which is about average for the time of year, so no surprises there.

For the first few days, it's a write-off. Friday the 11th through to Tuesday the 15th is a real flat spell with poor surf conditions and cross-shore winds messing things up. There’s basically nothing worth paddling out for.

We finally see a bit of life on Wednesday morning the 16th, with a tiny 0.7ft swell, but it’s not going to do anything for you. Thursday the 17th brings a small offshore wind, with a weak 1.0ft swell on the morning, but the combined energy is only 22 – that's barely a ripple.

The first real blip comes on Monday the 14th morning – a 5ft SSW swell with a very long 18-second period and moderate wave energy (1588). But it’s cross-shore wind, so it’ll be lumpy and chopped. It’s only a marginal call.

The standout – if you can even call it that – looks like Saturday the 19th morning. There’s a solid 10ft SSW swell, but the period is 12 seconds and it’s blowing 19 mph cross-shore from the SSE. That’s a lot of water moving around with messy wind. Combined energy is strong at 2380, but the wind state is described as "fresh cross-shore with lumpy cross-chop." That’s not clean. For this spot, with that size and wind, you’d need to be an expert to even consider it – and even then, the quality is poor. Actually, with that much wind and power on a sheltered spot like this, it might be more interesting for kite surfing than paddle surfing.

Sunday the 20th morning has another 7ft swell, but again strong cross-shore wind and only marginal conditions.

After that, the second week fades fast. Monday the 22nd to the end of the period is mostly flat or tiny surf with very low wave energy, all under poor surf conditions.

So, the best on offer? I’d have to point to Saturday the 19th morning for size – but don’t expect perfection. It’s a rough, bumpy day for experts only, if anyone bothers. And if you want a cleaner, smaller window, Monday the 14th morning is your best chance at something rideable, but barely. The rest of the 16-day window is pretty much a quiet, cross-shore mess.

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.
