The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming up for Nera Rivermouth.

Honestly, mate, the next couple of weeks are a real mixed bag. The first few days are pretty grim, with no surf to speak of. You’re looking at a flat spell stretching from Saturday the 22nd right through until Monday the 24th. The water temp is around 73°F, which is about average for this time of year.

We finally see a pulse of energy arrive on Tuesday morning the 25th. Nera Rivermouth will pick up a SSW groundswell, 4ft, with a very long period of 15 seconds. That long period means more power and better shape, but at a river mouth, it can get a bit straight. Combined wave energy is moderate (776), and with a light ESE cross-offshore breeze, the conditions will be clean. It’s beginner-friendly size, too.

Wednesday the 26th still has some okay waves, with the swell easing to 4ft from the SSW, period dropping to 14 seconds. Still clean in the morning with a light cross-off breeze.

If you’re willing to wait, the standout window looks like early September. On Wednesday the 2nd of September, the swell jumps up to 5ft from the SSW, with a long period of 16 seconds. The combined energy is strong (1208). It’s got a morning cross-offshore breeze, making for clean conditions. This is likely the best on offer, but it’s still a fair way out.

Then on Thursday the 3rd of September, we get another pulse: 6ft from the SSW, period 19 seconds – that’s a very long period groundswell. The energy is strong (1927). With a light cross-offshore breeze in the morning, it will be clean. This one’s for the experienced crew, as 6ft on a long period is no joke for beginners. Keep in mind, Nera Rivermouth is inconsistent, so these pulses are a big deal.

The rest of the period is filled with cross-shore and cross-onshore winds and low-energy slop. Not worth paddling out for.

That’s the rundown. Keep your eyes on that September window.

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.
