The Lowdown
Alright, let's get into it. This is Rusty, and I'm looking at what's on offer for the Nera Rivermouth over the next couple of weeks.
To be straight with you, it's a tough run. We're looking at a river and beach break that's sheltered and pretty inconsistent. The water temp is sitting at 73°, which is bang on average for this time of year, so no surprises there.
The only real window of opportunity comes early on. Thursday morning, August 27th, is your best bet. We've got a 3ft SSW groundswell rolling in with a very long 15-second period, and the wind is glassy from the ENE. Combined energy is moderate at 413, and it's expected to be good surf. That's the standout. But it's short-lived. By Thursday afternoon, the wind swings WSW and ruins it.
From there, it's a grim stretch. Friday through to the end of August is a write-off. The wind is onshore or cross-onshore, the swell is small or messy, and the conditions are poor. The first week of September doesn't look much better. There's a pulse of bigger swell arriving on Tuesday, September 1st, with a 5ft SSW swell, but the wind is howling cross-shore at 16 mph, making it choppy and ugly.
Now, here's a flicker of hope. Wednesday morning, September 2nd, is looking promising. The swell is up to 6ft from the SSW with a 15-second period, and the wind goes glassy again from the SE. The combined energy is strong at 1479. This is a solid, powerful groundswell. For a river mouth, that long period might make it a bit walled, but if it's clean, it'll be good. That's worth keeping an eye on, but it's a week away, so not a dead cert.
After that, the rest of the second week is a story of onshore and cross-shore winds, with the swell dropping and rising again. There's a brief glimpse of clean conditions on the morning of Monday, September 7th, with a clean 4ft SSW swell from the east, but it's not a huge standout.
Honestly, the best on offer is that Thursday morning, August 27th, for the clean, glassy conditions. The Wednesday, September 2nd, morning session is the other one to watch, but it's a long-range call. For most of this period, you're looking at a lot of blown-out, messy surf. The setup here is more likely to get a kiteboarder stoked than a surfer for most of the run.
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.
