The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Nera Rivermouth.
First thing you need to know, the water’s sitting at 73°, which is about average for late August, so nothing weird there.
Right now, there’s nothing rideable. The whole first week is a write-off, honestly. We’re looking at a gap of about four days of no surf worth paddling out for. The first real chance of anything decent doesn’t show up until Wednesday the 2nd of September.
Wednesday morning the 2nd is the standout. You’ve got a 6ft swell from the SSW, with a solid 15-second period. That’s a proper groundswell, and the energy is strong, right around 1312. The wind is light out of the ESE, meaning it’s clean and cross-offshore. The only thing is, the break is inconsistent and sheltered, so don’t expect a circus. But when it does come through, the shape should be good. Crowds are possible here, so get in early.
After that, things drop off again. The rest of the week is a mix of small, marginal surf and poor conditions. Tuesday afternoon the 1st has a 6ft swell with a 16-second period, but the wind is a fresh cross-shore from the SE at 19 mph, making it lumpy. Not worth it.
The second week is pretty quiet. There’s a small window on Monday the 7th, with a 3ft, 14-second SSW swell and clean conditions. That’s the best of a weak lot. The 8th has a glassy morning with 4ft, but the period is dropping and the quality is just okay. After that, it’s mostly small, weak swells under 2ft for the rest of the run.
Bottom line: if you’re free on Wednesday the 2nd, that’s your session. The rest is a waiting game.
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.
