Nera Rivermouth Surf Forecast and Surf Report

Alright, this is Rusty, and I’ve got a look at the Nera Rivermouth stretch for the next couple of weeks. Let’s be straight with you: it’s a slow start and there’s a lot of waiting involved, but there are a couple of windows that might just get your hopes up.

Right now, we’re looking at a long, quiet patch. The surf is pretty much non-existent through to Monday morning, with weak energy readings (0) and only tiny 0.7ft swell showing up under a light cross-off breeze. It’s clean, but there’s nothing to ride.

Monday afternoon is the first real flicker of life. Swell ticks up slightly to 1.0ft from the SSW with a very long 19-second period. The energy is still modest at 124, but that long period suggests some proper groundswell is trying to push in. It’s surfable, but very ordinary.

Now, the standout window kicks off on Tuesday the 25th of August. Morning brings a clean 4ft SSW swell (15-second period) and light cross-off winds from the ESE. Wave energy jumps to a solid 746, so the river mouth should start showing some lines. This is the best of the early run—clean, consistent enough for a beginner-friendly break, but the crowd could be a factor since it “sometimes” gets busy. Afternoon gets a bit lumpier as the breeze picks up to 12 mph, but still surfable.

Wednesday morning the 26th holds similar quality: 4ft SSW swell, 15-second period, light cross-off winds, and moderate energy (580). Clean conditions again. The water temp is sitting at 73°, about average for this time of year, so no surprises there.

Thursday the 27th morning is actually glassy—a light SSE breeze with 3ft SSW swell (15-second period, 408 energy). That’s about as clean as it gets for this spot, but it doesn’t last. By afternoon the breeze turns cross-shore and the surf gets choppy.

Then we hit a rough patch. From Friday the 28th right through to Monday the 1st of September, the wind is mostly onshore or cross-onshore, the swell drops off, and the energy dips below 150. The Sunday the 30th has some 3ft swell, but it’s cross-onshore and choppy—better for a kite than a paddle. This is a proper lull.

Things get interesting again on Tuesday the 1st of September. The morning shows 5ft SSW swell (17-second period) and a big jump in energy to 1108. But the wind is a moderate cross-shore from the SE at 16 mph, so it’s lumpy and marginal. By afternoon, the swell pushes to 6ft with 19-second period and energy rocketing to 2468, but the wind picks up to 19 mph and the cross-chop gets nasty. This is big, powerful groundswell—probably too much for beginners—and the wind will wreck it for any real quality.

Wednesday the 2nd of September is similar: 6ft in the morning, 6ft in the afternoon, both with 16-17 second SSW swell and moderate cross-shore winds. Energy is high (1969 and 1447), so there’s plenty of grunt, but it’s not clean. A sheltered reef or point would love this period, but at a river mouth exposed to cross-winds, it’s going to be messy.

By Thursday the 3rd, the swell completely drops out again, and we’re back to zero energy and poor surf. Friday the 4th offers a glimmer: clean 4ft SSW swell (15 seconds, 519 energy) with light cross-off winds in the morning. That’s the last real highlight, but it’s a one-morning wonder. After that, it’s back to tiny, weak, or wind-affected surf through to the end of the forecast.

So here’s the takeaway: your best chances are Tuesday the 25th through Thursday the 27th of August, with a standout being Tuesday morning for the cleanest conditions and solid 4ft SSW swell. The big swell on the 1st and 2nd of September has the size and energy, but the wind is against it—only worth it if you’re an expert and don’t mind lumpy conditions. The rest is a long stretch of waiting.

Rusty.
