The Lowdown

Alright, crew. Rusty here with the hard truth: this forecast tests your patience. We're looking at a solid chunk of nothing to start, a real dry spell for about five days. You'll be wondering if the ocean forgot about us.

Then we get one big, raw pulse of energy around the 12th, but it comes with a side of nasty onshore wind. We're talking a 7ft SSW groundswell on Saturday morning, jumping to a solid 12ft by the afternoon. The wave energy is off the charts, reading a huge 4546. But with the wind howling straight onshore, Nera Rivermouth is going to be a churning mess. This is strictly big-wave territory, and even then, it looks more like a fight than a surf. The water is sitting at a normal 73°, so nothing weird there.

The next morning, the 13th, is still chunky at 6ft, but the wind drops to a light breeze. It's still onshore, but the energy backs way off (1196). The period settles to 12 seconds, which should help the river mouth handle it a little better. It’s the closest thing to a standout here, but the swell is coming from the SSW, not its ideal SW direction, so it might be a bit lumpy and closed-out. It’s the best of a rough bunch, that’s for sure.

After that, it fades back down. The 16th offers a small, glassy 2ft wave, but it's inconsistent and pretty gutless. You'd be scratching for anything.

If that big weekend swell is as messy as it looks, grab the kite gear instead of the surfboard. The takeaway? Hang tight, don't get desperate, and remember that flat spells like this don't last forever. Forecasts can change. The long-range stuff is promising but it's a week and a half out, so we'll just have to wait and see.

Stay patient.

Rusty.

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.
