The Lowdown

Alright folks, Rusty here, casting an eye over the Nera Rivermouth forecast for the next couple of weeks. Let’s get into it.

First thing you gotta know: this break is a rivermouth setup, so it’s a bit sheltered and tends to be inconsistent. The water’s sitting at 73°F right now, which is about average for this time of year, so no surprises there.

The outlook starts slow, real slow. Friday the 28th and Saturday the 29th are a write-off – small, messy, and cross-onshore winds. Sunday morning shows a bit more size, about 5ft from the SSW, but the cross-onshore wind just chops it up. The wave energy on Sunday morning is moderate (572), but the quality just isn’t there. Monday and Tuesday are similarly poor with cross-shore winds and tiny surf. There’s a big flat spell from the 30th afternoon through the 1st of September.

Then things get interesting. Wednesday the 2nd of September is the first real standout. The morning brings clean conditions with light cross-offshore winds from the ESE, and the swell jumps to 7ft from the SSW with a 14-second period. That’s a solid groundswell with moderate to strong energy (1606). The wind is light, the break will have shape – this is a go. Just be aware, 7ft is getting toward the upper end for beginners, and with the rivermouth setup, it’ll have some punch.

After that, the surf gets more marginal through the 3rd and 4th, but there’s a sneaky window on Friday the 4th afternoon, where the wind goes cross-offshore and cleans up a 3ft SSW swell with a long 16-second period (energy 469). It’s not huge, but it’ll be smooth.

Now, the real highlight of the forecast is Friday the 11th of September. The morning session shows 7ft from the SSW, a very long 17-second period, light cross-offshore wind, and very strong wave energy (2213). This is excellent surf for experienced surfers. That kind of period and direction will push the rivermouth to its limit, creating deep, powerful lines. This one is a proper stand-out, but it’s a week and a half away, so keep your fingers crossed it holds.

A couple of other mentions: Wednesday the 9th of September morning has a big 8ft swell from the SSW, but with a shorter 13-second period and cross-shore winds. That’s big and a bit bumpy – really only for experts. And Thursday the 10th morning sees a clean 6ft from the SSW with 13-second period and light cross-offshore wind – another promising session, but the energy (1031) isn’t as strong as the 11th.

The forecast is a bit of a slow burn, but when it fires, it fires. The inconsistency of this spot means these clean, solid swells are precious. If you can wait, aim for the 2nd or the 11th.

Rusty.

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.
