The Lowdown

Alright folks, Rusty here with a look at what’s shaping up for Nera Rivermouth over the next couple of weeks. I’ve gotta be straight with you—this stretch ain’t looking generous. The entire 16-day window is a tough ask, with almost no proper windows for a decent paddle. We’ve got a real dry spell on our hands, so let’s break it down.

Right off the bat, Wednesday morning September 2nd sees a bit of a pulse from the SSW pushing 6ft at a long 15 seconds, with a combined energy of 1459. That’s got some weight, no doubt. But here’s the rub—winds are cross from the SE at 6 mph, and the spot’s sheltered nature makes it tricky. Water temp is sitting at 73°, right about average for this time of year. The problem is, the wave comment flags it as marginal with questionable tide, so it’s not gonna be clean or lined up. That afternoon the wind picks up to 9 mph cross-shore and it gets chop. Not the day to get excited.

Thursday September 3rd we see a drop. Morning has 5ft from the SSW at 13 seconds, but cross-onshore wind kills it. By afternoon everything fades to zero. From Friday September 4th right through to Wednesday September 9th, it’s a sad story. Swell heights barely tickle 0.7ft to 5ft, periods are all over the place, and cross or cross-onshore winds keep things messy. The energy readings are low—like 32 to 826—and the wave comments are all “poor surf conditions” or marginal at best. This is a long, frustrating gap with nothing worth paddling out for.

We get a brief flicker on the morning of Sunday September 6th with 4ft from the SSW at 16 seconds (826 energy), but again, cross winds and the setup just isn’t cooperating. Still marginal.

Now, Saturday September 12th rolls around, and here’s where things get a bit weird. We’ve got 8ft from the SSW at 17 seconds in the morning, with a combined energy of 3179—that’s serious energy. But the wind is cross-onshore at 16 mph, and the wave comment is still “poor.” That amount of swell with that much wind at a river-mouth beach setup is gonna be a mess. That’s more of a kite-surfing proposition than a clean surfing wave. Period over 15 seconds makes it a groundswell, but at a beach break it’ll break straight and be hard to manage. This one’s for experts only, if anyone bothers.

After that, from Sunday September 13th onward, it’s another dead zone. Tiny waves, zero energy, poor conditions. By September 17th, we’re looking at nada.

Honestly, there’s no standout here. The best of a bad bunch is that early pulse on Wednesday September 2nd morning, but even that’s a marginal wobbly mess. You’d be better off waiting for the next system to roll through.

Rusty.

A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu.

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.
