The Lowdown
Alright folks, Rusty here. Let’s get this straight. We’re looking at the Nera Rivermouth for the next couple of weeks. That’s a river and beach setup, a sheltered spot, and it’s best with swell from the southwest. The water is sitting at 73°, which is pretty normal for this time of year, nothing weird going on temperature-wise.
The kick-off is a bit of a tease. On Thursday, the 27th of August, we’ve got a solid window. The morning is looking glassy with a 3ft SSW groundswell rolling in with a period of 15 seconds. That’s proper long-period energy, which means those waves will have some shape and punch, and the combined energy is a solid 413. The water is glassy, wind is barely there – it’s clean. This is probably the best on offer early on. The afternoon stays small but still glassy, though conditions are a bit more ordinary.
Friday the 28th and Saturday the 29th are a write-off. The wind swings onshore or cross-onshore, the swell gets messy or too small. Saturday morning gets a bump up to 4ft, but it’s cross-on and choppy. Not worth paddling out for.
Sunday the 30th through the end of the first week is a real dry spell. Cross-shore winds, lumpy, messy, and the swell drops to almost nothing by Monday. The waves are there on paper, but the wind is just ruining any chance of a good session. The energy on the 30th is still moderate at 531, but it’s all cross-off and messy.
The second week starts with a whimper. Monday the 1st of September is a no-go, and Tuesday the 2nd has a big jump in energy – 1703, which is strong – with a 7ft SSW swell, but the wind is cross-shore and the conditions are only marginal. That’s too big for beginners, and the wind is just not cooperating.
Then, we hit the real standouts. Wednesday the 9th of September is the one to circle. The morning brings a 4ft SSW groundswell with a killer period of 19 seconds, and the combined energy is 1773. The wind is a light cross-off, and it’s clean. This is proper groundswell, so it might be a bit straight at the beach break, but for a river/reef setup, this is the best shape we’ll see. The afternoon is just as good, with 6ft and 17-second period, still clean. After a long gap of nothing, this is a true standout.
Thursday the 10th of September is worth a mention – glassy morning with 4ft and good energy – but it’s not as strong as the day before. The rest of the period fades out with cross-shore winds and ordinary conditions.
So, the best call is Thursday the 27th of August for a clean, small session, and the real highlight is Wednesday the 9th of September. That’s the one to wait for. The rest of the time is a lot of wind and chop. For a beginner spot, the 7ft+ days on the 2nd and 11th are too much, and the wind makes it look more interesting for kite surfing than a paddle.
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.

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.
