The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Nera Rivermouth is a real mixed bag, and a pretty frustrating one at that. Mostly, it's going to be a waiting game. We've got a solid pulse of groundswell pushing through mid-week, but the wind is going to be a constant battle. The real standout, and the only time I'd really get excited, is on the morning of Tuesday the 25th of August. The water temp is sitting at a pretty normal 73° for this time of year, nothing weird there.
Alright, let's break it down. We kick off on Monday the 24th, but it's a non-starter. Tiny 0.7ft of 18-19 second groundswell, and a cross-off breeze. The combined energy is a weak 32 (that's barely a ripple) and then 126. It's clean, but there's just nothing to ride. Forget it.
The first real hope comes on Tuesday morning the 25th. We've got a 4ft groundswell from the SSW with a sweet 15-second period, and the combined energy is a solid 746 – that's a proper pulse of energy. The wind is a light cross-off from the ESE, which will keep the river mouth pretty clean. This is the best window of the whole forecast. The afternoon stays rideable with the same 4ft swell, but that wind picks up to a moderate 12 mph, making it a bit lumpy. Still, the morning is your time.
Wednesday the 26th is still fun, with 4ft of the same 15-second SSW groundswell in the morning. The energy is still a decent 491. Light cross-off wind again. It's a good option if you missed Tuesday. The afternoon gets a bit more breeze on it.
Thursday the 27th starts off okay with 3ft of 15-second swell and a very light cross-off breeze (3 mph, almost glassy). The energy is down to 413, but it's clean. The afternoon turns to a cross-shore wind though, making it messy and poor.
Then it all goes pear-shaped. From Friday the 28th right through to the end of the first week of September, we get a mix of poor conditions. The swell drops off, the wind swings onshore or gets strong and cross-shore, and the quality just disappears. We get a blip of 5ft on the 2nd of September, but it's with a lumpy cross-shore wind, so it's a write-off for a paddle board. That kind of setup is more for the kite surfers.
The only other glimmer of hope is a surprise glass-off on the afternoon of Friday the 4th of September. The wind goes dead calm, and we get a clean 3ft of 18-second SSW groundswell. The combined energy is a solid 405. It's a long way out, but if that glass holds, it could be a sneaky, uncrowded session. The rest of the time after that is just small, choppy, or cross-off but tiny. It's a frustrating run, but that's the river mouth for you. It needs everything to line up.
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.
