The Lowdown

Alright folks, Rusty here. Let's have a look at what Nera Rivermouth has got cooking for us over the next couple of weeks.

First up, it's a pretty quiet start. There's a bit of swell on the way for Sunday the 6th of September, with a 5ft SSW swell showing up, but it's got a cross-shore wind on it and the call is marginal at best. The water temp is sitting at a pretty normal 73°F for this time of year. Don't get your hopes up for that one.

From Monday the 7th right through to Friday the 11th, it's a real dry spell. The swell drops right away and the wind is all over the shop – onshore, cross-onshore, just messy. There's not much point paddling out. This is one of those stretches where the forecast just isn't giving us anything to work with.

Now, come Saturday the 12th, things get a bit more interesting, but it's not straightforward. We've got a proper 10ft SSW swell rolling in, and the energy is strong – we're talking over 5000 (5034) in the morning. That's a lot of water moving. However, the wind is cross-shore and the conditions are described as marginal. That size is for experienced surfers only – way too big for beginners. The period is a long 17 seconds, which means it's a groundswell. At a river mouth, that long period can make things a bit walled-up and straight, so it's not a sure thing for perfect waves. Sunday the 13th still has a solid 6ft SSW swell, with that strong energy (1321), but again the wind is messy.

After that, we hit another quiet patch from the 14th right through to the 17th. The swell is tiny or non-existent, and the wind is howling from the southeast. Not worth a look.

Finally, we get a glimmer of hope towards the end of the outlook. On Friday the 18th, we see a 6ft SSW swell pick up with that long period (18 seconds) and moderate energy (1765). It's still marginal, but it's something. Then, the standout looks like Saturday the 19th of September. The morning session is the pick: a clean 6ft SSW swell, a long 16-second period, strong energy (1592), and a light cross-onshore breeze. The water temp will be about average. That's a solid size for a river mouth, and the light wind should keep it reasonably clean for those who know the break. It's a beginner-friendly spot normally, but at 6ft, it's pushing into intermediate territory. Crowds can pop up here sometimes, so keep an eye out.

Sunday the 20th morning also has a big one – 8ft SSW with a 16-second period and over 3000 energy (3016), and the wind looks almost glassy from the SSW. That's a big, powerful swell, only for experts. The river mouth might handle it, but it could be a beast.

All in all, the first week is a write-off. The second week has a few days with size, but the wind is always a factor. Saturday the 19th morning is your best bet for a cleanish session. The rest is either too small, too windy, or too big and tricky.

Rusty out.

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.
