The Lowdown

Alright folks, Rusty here. Let's be straight with you: the next couple of weeks are looking pretty bleak for a paddle. This stretch of coast is set to be frustratingly small and messy for the most part, with only one real window of quality to get excited about. We'll be paying the price for a while, but there is a light at the end of the tunnel.

Right now, we're looking at the Nera Rivermouth (Rivermouth). The water temp is sitting at about 73°F, which is pretty much normal for late August. The start of this run isn't anything to write home about. Wednesday the 26th has some clean, rideable waves in the 4-4ft range with a 14-15 second period, and light offshore winds. It's surfable, but the energy is weak and the direction is a bit off for this spot. Thursday morning stays clean and small, but the swell fades through the day and the surface goes glassy, which is nice, but there's just not enough push.

From Friday the 28th, it all turns to mush. The wind goes onshore and the wave heights drop right off. We’re looking at a solid stretch of tiny, chopped-up closeouts through the weekend and into next week. The wind stays strong and cross-shore, creating lumpy cross-chop. It’s a write-off for surfing. Honestly, with that strong cross-shore wind and small, weak swell, the setup here looks more interesting for kite surfing than paddle surfing. The combined swell energy is very weak, mostly in the low hundreds or less, like on the 31st when it's only at 66. There’s a long stretch of nothing from the 28th through the 1st of September.

Now, I know this seems grim, but here’s the thing. Mark your calendars for a week from now: Wednesday, September 2nd. The forecast is showing a proper pulse of groundswell. We're looking at a 6ft SSW swell with a 15-second period, which is a serious step up. The energy is strong, with the combined swell energy jumping to 1459. And get this – the winds are predicted to be light and offshore, right out of the SE. This is the standout window. The river mouth will have some proper shape and power, but it might be a bit much for beginners. It won't be perfect, but it's the best we're going to see. That Wednesday afternoon looks like it gets messy again as the wind swings, so the morning session is the one.

After that, the following week looks like more of the same – inconsistent, often small, with onshore and cross-shore winds. There are a few attempts at a pulse, like on the 9th of September with 5-5ft swell, but the wind is set to be strong and cross-shore, ruining any potential. It’s a case of watching and waiting, but that Wednesday morning is the true standout. The conditions can always change, but this is what we’ve got.

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.
