The Lowdown
Alright, Rusty here. Let’s take a look at what’s shaping up for Nera Rivermouth.
Honestly, mate, it’s a bit of a flat spell for the most part. The next week and a half is looking pretty rough – mostly small, messy, and cross-shore. There’s a lot of weak energy and poor conditions, with a real lack of quality. The only brief window of hope comes on Wednesday, the 2nd of September, and even then it’s a one-session deal.
The first real sign of life shows up on the morning of Wednesday, the 2nd of September. We’ve got a solid pulse of 7ft swell from the SSW, with a long period of 15 seconds. That’s a proper groundswell. The combined energy is strong at 1613, so there’s some grunt behind it. The wind is light and cross-offshore from the SE – clean conditions. The swell direction matches the optimum from the guidance, so the setup should be working. This is your standout. The water temp is about 73°F on the 27th, which is pretty normal for this time of year. Keep in mind, this is an inconsistent spot that rarely breaks, so you’ve got to be on it when it happens. The 7ft face height is getting into the territory where it’s not for beginners, but it’s still manageable for most.
The rest of the window is a write-off. From Thursday afternoon the 27th right through to the morning of the 7th of September, it’s mostly poor surf conditions, with a few days of no swell at all. There’s a couple of days around the 7th and 8th of September with small 2-2ft SSW swell and offshore winds, but the energy is weak (under 200) and the waves are just ordinary. Not really worth paddling out for unless you’re desperate. After that, it’s back to small, weak, and choppy through to the 11th.
So, if you’re keen, you’ve got one morning – Wednesday the 2nd of September. Get out there early, because the afternoon turns to mush. Otherwise, it’s a long wait for much of anything.
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.
