The Lowdown

Alright folks, Rusty here. Let’s get into it.

Well, I gotta be straight with you – this is a tough one. The first week and a half is looking pretty flat and uninspiring. We're talking about Nera Rivermouth, and for the first few days, the swell is barely a ripple. You’ll see tiny 0.7ft waves from the SSW with long periods, sure, but the energy is just not there. The combined energy readings are in the single digits and low twenties – that’s almost nothing. It’s going to be a frustrating wait for any real surf.

The first real sign of life doesn't arrive until Thursday, the 13th of August. We get a small bump to 1ft from the SSW, but the real kicker is a jump in energy to 142 in the afternoon. Still, the wave height is tiny, so it’s more of a tantalising tease than anything rideable for most of us.

Things get a bit more interesting from Friday, the 14th, onward. The swell builds to 2ft on Friday morning, then 3ft by the afternoon. The combined energy is climbing into the 160s and 260s – that’s moderate energy now. Saturday the 15th sees the swell push over 7ft from the SSW, with the energy screaming into the 1100s. That’s strong wave energy. But here’s the catch – the wind is a moderate cross-shore from the SE, which is going to chop it up. The period is in the 12-13 second range, so it’s a decent groundswell, but for a river-and-beach setup like this, that long period tends to make the waves break a little straight and harder to handle.

Sunday the 16th of August is the standout, if you can call it that. The swell is 4ft in the morning, building to 5ft in the afternoon from the SSW, with a very long period of 21-23 seconds. The combined energy is massive – 1815 in the morning, 2414 in the afternoon. That’s strong to very strong energy. But the wind is a fresh cross-shore from the SE at 19 mph, so it’s going to be lumpy and messy. This is expert territory because of the size and the tricky conditions. The water temp is about 73°F, which is pretty normal for the time of year.

After that, the swell drops back down through the following week, with some cleaner but smaller conditions on Tuesday the 18th and Wednesday the 19th of August. On Tuesday, we get 4-4ft with a clean cross-offshore wind from the ESE and the energy still decent at 459-565. That’s actually the best combination of size and clean conditions in the whole window. Wednesday morning is dead flat calm, glassy, with 3ft, but the energy is lower.

Honestly, if you’re looking for a session, the best bet is Tuesday the 18th of August. It’s not huge, but it’s clean and the swell is there. After that, it fades out again into the 21st and 22nd, with tiny waves and poor conditions.

So, there’s a window from the 15th to the 18th, but it’s a mix of messy and just okay. Keep your expectations low and be ready to get skunked.

Rusty.

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.
