The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this is a grim outlook for Nera Rivermouth. The next 16 days are basically a write-off. We’ve got a long gap of nothing to start – the first few days are a total bust, and the pattern doesn’t improve. It’s not a great stretch for this spot, and honestly, it’s a patch that’s more likely to see you sitting on the bank than getting wet.
First up, Tuesday the 28th of July. The morning is flat as a tack – zero energy. By afternoon, a weak 5ft swell tries to show up from the SE, but it’s a short-period 6 seconds of windswill, and the cross-shore wind (12 mph) is ruining any chance of a wave. The water’s at 74°, which is pretty much normal for this time of year.
Wednesday the 29th is tiny. A 1ft SSW groundswell with a long 12-second period gives you a hint of shape, but it’s barely a ripple. The wind is light and cross-off, making it clean, but there’s just no push. The combined energy is a weak 29.
Thursday the 30th is the closest we get to a “maybe.” Morning brings a 1ft SSW groundswell with a very long 16-second period, and its combined energy gets up to 195. The wind is light and cross-off, so it’s clean. But it’s tiny, and the long period means it’ll roll straight through at this river-and-beach setup. It’s surfable but very ordinary.
Friday the 31st is the pick of a bad bunch. Morning goes glassy – zero wind – and there’s a 3ft SSW groundswell with a 14-second period. The combined energy is a moderate 236. It’s still small, but with the glassy conditions, you’d get a few clean, slow peelers if you’re patient. The afternoon turns to light rain and a slight cross-on wind, so that window is short.
From Saturday the 1st of August onward, it’s a hard pass. The swell bumps up to 3ft to 5ft, but the wind is a solid 16 mph cross-shore, creating a choppy mess. The combined energy spikes to 815 on Saturday afternoon, but it’s all wind-affected junk. The rest of the first week and into the second week is the same story: wind from the SSE or S, 9 to 19 mph, always cross or cross-on, with the swell never getting above 4ft and often dropping to barely 0.7ft.
By the second week, from the 3rd of August onwards, the swell is mostly a long-period ghost – 0.7ft to 2ft – but every session is blown out by a moderate to fresh breeze. The combined energy never gets strong enough to overcome the chop. On the 8th of August, a fresh 19 mph cross-on wind with a 3ft swell makes it look more like a kite-surfing setup than a paddle session.
Honestly, there’s no standout here. The only day worth a look is the morning of Friday the 31st of July for the glassy conditions, but you’ll be fighting for a knee-high wave. For the rest, save your energy. Forecasts can change, but this run looks pretty locked in.
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. 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.
