The Lowdown

Alright, surfers, Rusty here. Let’s be straight with you. We’ve scanned the charts for the next couple of weeks, and I’m not gonna sugarcoat it: the Nera Rivermouth is looking pretty grim for a while. This stretch is more about keeping the board in the car than getting wet.

For the first stretch, from Tuesday the 8th through Friday the 11th, it's just poor surf conditions. The swell is tiny and messy, mostly around 2ft to 4ft, and the wind is all over the place – cross, cross-on, doesn’t matter, it’s all gonna be choppy. The wave energy is weak to moderate, just 154 to 367. Not worth the paddle out.

Then we hit a change over the weekend. Saturday the 12th rolls in with a bigger push of swell, around 10ft, and the energy jumps way up to 4708, which is strong. But here’s the kicker – the wind is a fresh 30-37 mph cross-shore. That’s gonna turn it into a lumpy, cross-chop mess. The report calls it "marginal" at best. With that much swell and that much wind, this looks more interesting for the kite surfers than for us paddle surfers. It’s just too messy and too big for a fun day.

Sunday the 13th stays poor, and Monday the 14th has a bit of swell, 7ft, but again, a fresh 30 mph cross-shore wind ruins the party. The energy is strong at 2276, but it's all for nothing if you can't surf it.

Finally, on Tuesday the 15th, the wind backs off to a gentle breeze from the SE, and the afternoon looks clean. There's 4ft of SSW swell with a 14-second period, and the energy is a moderate 580. That’s our one genuine window. The Nera Rivermouth (this is a sheltered river and beach setup) is going to be your best bet. It's an inconsistent spot, and it's a beginner wave, so this is the one to keep an eye on. Glassy conditions will make it worthwhile.

After that, we're back to poor surf for the following week. Wednesday the 16th through to the 23rd is mostly small, weak, and onshore. There are a few pulses of energy – like Friday the 18th and Saturday the 19th with 5ft and 5ft swell – but the winds are just too strong to make anything of it. The 20th and 23rd are also rated marginal, with moderate energy, but the wind is still not doing us any favors.

So, if you can only get out once, make it Tuesday the 15th in the afternoon. Otherwise, it’s a dry spell for a while. The long-range stuff is promising but less certain, so we’ll just have to wait and see.

Later, Rusty.

Information about the Nera Rivermouth Surf forecast

The above surf forecast table for Nera Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Nera Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Nera Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
