The Lowdown
G’day, Rusty here. We’ve got a bit of a mixed bag for Nera Rivermouth over the next couple of weeks. To be straight with you, the first standout doesn’t arrive until Monday, 14 September, and even then, it’s not a full day of glory. There’s a long gap with nothing good to recommend after that.
The first real highlight is Monday morning, 14 September, at Nera Rivermouth itself. The ocean is pumping a solid 5 ft of SSW swell, with a very long 18-second period between sets – that’s proper groundswell energy. The combined energy is strong at 1588, so there’s plenty of push. Winds are light and cross-off from the SE at 6 mph, which will keep the surface clean. This setup tends to like a river mouth, that long period might make it a bit too straight for the beach sections, but the mouth itself should be doing its thing. The water temp is 73°F, which is dead normal for this time of year. It’s a beginner-friendly wave, but with nearly 5 ft and that power, maybe not the best for total novices. Keep in mind this break can be inconsistent, and it can get crowded sometimes.
Monday afternoon, the wind picks up to a moderate cross 16 mph from the SE, and the surf turns to junk – cross-chop city. From there, we hit a long, dry spell. Tuesday the 15th through to Sunday morning, 20 September, is basically flat or blown-out. The wind is cross or cross-on, the waves are tiny or nonexistent, and the conditions are just ordinary. There’s some swell moving through on the 18th (8 ft to 8 ft), but it’s getting hammered by fresh, messy cross-shore wind. Not worth paddling out for.
The next bit of interest isn’t until Sunday morning, 20 September, and again it’s only a marginal call. That 7 ft SSW swell with a very long 16-second period looks juicy on paper, and the combined energy is up at 1962, but it’s still under that moderate cross wind. You might get a few if you pick your bank, but it’s not clean. Monday 21st morning is a similar story – 6 ft, 14-second SSW, moderate cross – marginal at best.
If you can wait, there is one final, more promising window: Tuesday morning, 22 September. The swell is 7 ft from the SSW, cranking with an 18-second period, and the combined energy hits 2371. That’s powerful stuff. The wind is still a moderate cross from the SE, but the morning might clean up before the wind really gets on it. This is the best call in the whole fortnight. Just note: with the swell over 8 ft on the following day’s readings, it’s expert territory. Tuesday morning’s 7 ft is at the upper edge of what’s okay for a confident intermediate.
After that, a gap of a few days with hardly any real surf. The 25th of September (Friday) sees some weak, ordinary 3 ft SSW leftover, and then it pretty well fades into the end of the month. No standouts in the second week – just tiny, long-period leftovers with very low energy (42 at best on the 26th). You’d be better off waiting for the next proper swell.
The long-range outlook for the 22nd is promising but less certain this far out. Keep an eye on it.
Stay salty.
