The Lowdown
Right, crew, Rusty here. Let’s have a look at what’s on offer for the Nera Rivermouth stretch over the next couple of weeks.
First off, we've got a river and beach setup that’s pretty sheltered, so it doesn't see a lot of action. The water temperature is sitting at 74°, which is bang on average for this time of year – nothing to write home about, but it’s comfortable.
We’re starting with a bit of a slow burn. Friday morning, the 24th of July, we’ve got a tiny 2ft SSW swell, but man, it’s glassy. The wind is just a whisper from the SSE, so the surface is clean. The combined energy is weak (131), and it’s inconsistent, so it’s a bit of a gamble. For a beginner, it could be a fun little paddle, but don’t expect much. Friday afternoon goes flat and cross-on, so that’s a write-off.
Saturday the 25th is a mess. The swell drops to 1ft with a cross-shore breeze, and the energy is a paltry 45. Sunday the 26th is where things get interesting, but it’s not for the faint-hearted. We’ve got a solid 7ft SSW groundswell on Sunday morning, with a very long period of 15 seconds. The combined energy is strong (2220). This is a big, powerful swell. The problem? It’s cross-shore wind at 15 mph, which will chop it up. The swell direction (SSW) matches the optimum (SW) pretty well, but the wind is a killer. Sunday afternoon is even bigger at 8ft, but still cross-shore. This is expert-only territory, and even then, the conditions are marginal. The long period will make it dumpy and tricky at a river mouth, though it could draw some lines if you’re brave.
Monday the 27th through Tuesday the 28th is still messy with cross-shore winds and dropping swell, and the energy is moderate (793 to 548). Not worth a trip.
Now, there’s a glimmer. Thursday morning the 30th of July, we get a little 2ft SSW swell, but the wind goes light offshore from the ENE. The combined energy is moderate (211) and the surface is clean. It’s surfable, but very ordinary. Still, a clean wave is a clean wave.
The standout for the whole forecast is Friday the 31st of July. Morning brings a 3ft SSW swell, with a very long period of 16 seconds and a light offshore wind from the NE. The combined energy is moderate (463) and the forecast says "expect good surf conditions." This is the best on offer. The swell direction is a perfect match for the optimum SW, and the offshore wind will make it glassy. The crowd situation is "sometimes," so you might have a few others, but it’s worth it. Friday afternoon goes glassy with a 3ft swell, but it’s a bit weaker.
After that, it’s a long, dusty stretch. From Saturday the 1st of August right through to Saturday the 8th of August, it’s a mess of cross-on and cross-shore winds, with the swell staying small or dropping out completely. The energy readings are mostly weak, and the wind is never good. There are a few days in the second week with moderate energy (like the 4th of August at 1901), but the wind is cross-on and choppy, so it’s not worth paddling out. The 5th of August has a 5ft swell with a 17-second period, but again, cross-shore wind and marginal conditions. It’s a kite-surf setup at best on those bigger days.
So, the bottom line: Friday the 31st of July is your one and only true standout. It’s clean, the swell is solid, and the wind is perfect. Everything else is a gamble or a washout. If you’ve been waiting, that’s your window.
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.

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.
