The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at a tough stretch for Nera Rivermouth. The setup is a sheltered river and beach break that needs a clean window to work, and honestly, over the next 16 days, we just don’t get one that’s worth paddling out for. The wind is almost always cross or cross-onshore, and the conditions are consistently described as poor. There’s a real gap here, with no quality surf on offer at all.

We kick off on Wednesday, the 9th of September. The morning has a 4ft SSW swell, but with a 9 mph cross-onshore, it’s choppy. The combined energy is moderate (367), but the wind just ruins it. That pattern sticks through Thursday and Friday, with the wind picking up to 16-19 mph, making it lumpy and messy. The swell period jumps to a very long 22 seconds on Friday morning, but with that strong cross-shore wind, it’s just a washing machine.

Saturday the 12th morning sees a bigger pulse of 8ft from the SSW, with a period of 17 seconds. The combined energy is strong (4090), but it’s still cross-shore at 19 mph. That’s a big, lumpy, expert-only slab if you’re desperate, but the wind won’t let it be clean. Saturday afternoon, the period drops to a terrible 6 seconds, so that’s a write-off.

Sunday and Monday see the swell drop away, with Monday having no real wave height. The wind finally goes light and cross-off on Monday morning, but with zero swell, it’s a flat, clean lake. Cruel.

The following week has a few more pulses of marginal energy. On Friday the 18th morning, we get 6ft from the SSW with a 14-second period (moderate to strong energy at 1411), but it’s still cross-shore at 16 mph. The same story repeats on Saturday the 19th morning with 6ft and a long 19-second period, and again on Sunday the 20th morning with 6ft. The wind never lets up enough to make it good. The water temperature is about average for this time of year, which is a small comfort, but it doesn't help the waves.

For a beginner spot that’s inconsistent, this is a blank run. There’s no standout session. The best you could hope for is a marginal, lumpy, expert-only session on the bigger days if you’re a masochist, but the wind is a deal-breaker every time. It’s a no-go from me.

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.
