Nera Rivermouth Surf Forecast and Surf Report

G’day, Rusty here. Let’s be straight with you—this 16-day window for Nera Rivermouth is pretty grim. We’ve got a long dry spell before anything even worth paddling out for, and even then, it’s only a small window of just-okay waves before it turns messy again.

The first real chance of surf kicks off on Tuesday morning, the 25th of August. That’s when we finally see a pulse of 4ft SSW groundswell rolling in with a nice long 15-second period, carrying moderate wave energy (756). The morning will be clean under a light ESE breeze—cross-off, so it’s not perfect but it’s workable. The river-and-beach setup here is sheltered and inconsistent, so don’t expect a full day of it. The afternoon holds similar size and period, but the wind picks up a bit, so the morning is your best bet. For a beginner-friendly spot, 4ft is a bit of a push, but the long period means the waves will have shape and the sets will be spaced out, making it easier to get out the back.

Wednesday the 26th of August offers a slight drop-off—4ft SSW at 15 seconds in the morning (moderate energy at 485). Winds stay light and cross-off, so it’s still clean. But by the afternoon, the swell drops to 3ft and the energy fades (389), and conditions become “very ordinary.” Thursday the 27th sees the swell slip to 3ft with a 15-second period (322 energy), and the morning goes glassy—dead calm, which is a dream for clean faces. But the wave heights are small, and the spot is inconsistent, so it’s really only worth a look if you’re happy cruising on a longboard.

After that, it’s all downhill. From Friday the 28th through to the end of the forecast, we get a mix of onshore winds, lumpy chop, and tiny, weak swells. There’s a brief uptick on Tuesday, the 1st of September, with 3ft SSW at 19 seconds (799 energy), but the wind is a moderate cross-shore, creating chop. Not worth getting excited about. Then the 3rd of September drops a 4ft SSW swell with a very long 19-second period and strong energy (1120), but the wind is onshore, so it’s a mess. Same story on the 4th with 5ft SSW (16 seconds, 1082 energy)—size is there, but the wind is cross-onshore, making it choppy and only marginal for anyone. Anything over 5ft is too big for beginners here, and with the wind against it, it’s not a fun paddle.

The best call in this whole outlook is the Tuesday morning, the 25th of August. It’s the first real surf, the swell is solid, the period is long, and it’s clean. That’s your standout. The glassy Thursday morning, the 27th, is a close second if you don’t mind the smaller size. For the rest, you’re better off checking the wind forecasts or finding something else to do.

Water temperature here is 73°F, which is about average for this time of year—nothing unusual.

Stay hopeful, waves can turn around. This is Rusty, signing off.
