The Lowdown
Alright, Rusty here. Let’s be straight with you. For the next 16 days, there’s a long stretch of nothing. It’s a tough one.
We’ve got Nera Rivermouth (Nera-Rivermouth) on the table, and for the first week and a half, it’s pretty much a write-off. The swell is tiny, mostly around 0.7 ft to 1 ft, and the wind is all over the place. The combined energy is weak as a cup of tea most days, with values like 9, 16, or 39 (weak energy). There’s a bit of a bump from August 14th through the 17th, with the swell picking up to 5 ft at one point, and the combined energy getting into the moderate range (254 to 648), but the wind is a problem. It’s cross-shore or cross-onshore at 16 to 22 mph, making it choppy and lumpy. The wave comments are all “poor surf conditions.” This is a river and beach setup, so with that wind and messy swell, it’s looking more like a kite-surfing spot than a paddle-surfing one.
There’s a glimmer of hope on August 18th. The swell drops back a bit to 3 ft from the SSW, but the wind finally turns cross-offshore from the ESE at 12 to 15 mph, and the wave comment says “expect good surf conditions.” The combined energy is 493 (moderate energy). It’s not a standout by any means, but it’s the best on offer. The water temperature is 73°, which is about average for the time of year. Still, Nera Rivermouth is inconsistent, so don’t expect a set every few minutes.
After that, it drops off again. From the 19th onward, it’s back to tiny or flat swell, with the combined energy falling to 0 by the 23rd. There’s a glassy moment on August 24th with no wind, but the swell is just 1.0 ft from the west with a 4-second period – barely a ripple.
So, the only real window is August 18th. It’s not a classic, but if you’re desperate for a paddle, that’s your best bet. Everything else is a no-go.
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.
