The Lowdown
Alright, Rusty here, and I gotta be honest – Nera Rivermouth is in a real slump for a while. The water’s sitting at about 73°F right now, which is pretty standard for the season, nothing wild.
The first week is mostly a bust. From Wednesday the 19th through Monday the 24th of August, you’ve got a stretch of flat or junk surf. The combined energy readings are either zero or in the low hundreds – that’s weak, and the wind is mostly cross or lumpy. There’s a multi-day gap where it’s basically a lake. Not good.
Tuesday the 25th of August finally shows a pulse: 3ft to 3ft of SSW groundswell with a 15-16 second period. That’s long-period energy, which can be a bit tricky at a river-and-beach break, but with light offshore winds from the ESE at 6 mph and clean conditions, you might squeeze out a few small ones. It’s still just “ordinary” surf.
Wednesday the 26th is more of the same – 3ft SSW swell, clean in the morning. Thursday the 27th gives you a glassy 2ft swell in the morning, but it’s tiny.
The real highlight – the only highlight – is Monday the 31st of August. Swell pushes up to 4ft to 4ft from the SSW, and the combined energy jumps to strong (300-403). Winds go glassy with a light NNE/NNW breeze, meaning clean, smooth waves. That’s your best bet in the whole forecast. Expect a few other folks out there, but the waves will be worth it for a beginner or anyone wanting clean small waves.
Tuesday the 1st of September jumps to a raw 8ft of SSW swell – that’s for experts only, and the wind and rain make it messy. After that, it’s back to poor conditions and dropping energy. So, if you’re itching for a wave, aim for that Monday the 31st.
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.
