The Lowdown

Alright, this is Rusty. Let's have a look at the surf ahead for the next couple of weeks.

Well, to be honest, it's a pretty grim outlook for the Nera Rivermouth. The first real bit of swell that shows up on Sunday the 6th isn't worth paddling out for. The wave energy is moderate (818) but the wind is cross, the period is long at 14 seconds, and it's just too messy. The water temp is sitting at 73°F, which is bang on average for this time of year, so at least you won't be freezing.

We then hit a dead zone. From Monday, the 7th, right through to Friday, the 11th, it's essentially flat or poor. The wind is either onshore or cross-onshore, the swell is tiny, and the scores are a zero. It's a proper blank run.

Then, on Saturday the 12th of September, things get a bit wild. The combined energy of all swells directed here jumps to a massive 5286, with a 10ft swell from the SSW and a 17-second period. That is a lot of power, but it's a cross-shore wind, and the spot is a river and beach setup. For a river mouth, that long period groundswell can make things break a bit too straight. At 10ft, this is expert territory only, and with the wind, it's messy. The best of a bad bunch is probably the Saturday morning, but even then the score is a 2. Honestly, with that much power and the cross-shore wind, it might be more interesting for the kite crew than paddle surfers.

After that, it drops off again. Sunday the 13th has 6ft, but the wind picks up to 19 mph, creating a lumpy cross-chop. Then from the 14th, we are back to zero for a few days, with a tiny bit of weak, short-period junk showing up from the 15th onwards. A 4ft swell with a 6-second period on Tuesday the 15th is just not worth it. The rest of the run into the 21st is all tiny, weak, and messy.

There is no standout here. The best you could possibly hope for is the Saturday the 12th if you are an expert and don't mind the wind, but it's a gamble. For the rest of us, it's a waiting game.

Rusty.

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.
