The Lowdown
G’day, Rusty here. Let’s have a look at the next couple of weeks for Nera Rivermouth.
Straight up, it’s a pretty bleak stretch. There’s no surf worth paddling for the first few days, so you’re looking at a real dry spell. The first real glimmer shows up on Sunday the 6th, but honestly, even that’s a tough sell. The best of a very average bunch is that Sunday morning. We’ve got a clean, light cross-offshore breeze with a 3.6ft swell out of the SSW, and the water’s sitting at 73°, pretty normal for this time of year. The combined energy is moderate (818), and with a long 14-second period, it’s got some push. But this is a river-and-beach setup, sheltered and inconsistent, so don’t expect much. It might give up a few fun ones for a beginner if you’re keen for a paddle, but it’s hardly a standout.
From there, it’s mostly poor surf conditions with cross or onshore winds messing things up. Monday the 7th and Tuesday the 8th are write-offs. Wednesday the 9th and Thursday the 10th look a bit choppy and cross-onshore. There’s a spike in size on Saturday the 12th – 9.8ft of SSW swell with very strong energy (5559), but with a cross-shore moderate breeze and a period around 17-18 seconds, it’s really only for experienced surfers. At that size, it’s too big for beginners, and the break is inconsistent. Sunday the 13th still has decent size, but the wind isn’t ideal.
The long-range window, around the 20th of September, shows more size – 7.2ft to 7.9ft – but again, wind is cross to fresh cross-shore, so it’s marginal at best. Honestly, this stretch is one to skip. If you’re desperate, the Sunday 6th morning is your best shot, but don’t expect much. The rest is a waiting game.
