The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Nera Rivermouth over the next couple of weeks.
First off, be patient. The first week is pretty lean. We're looking at a whole heap of days with nearly nothing rideable, so don't bother rushing down until we get into the back half of next week.
The first real glimmer of hope shows up on Monday the 24th in the afternoon, with a tiny 1ft swell bump from the SSW, but it's weak. The real action starts to build on Tuesday the 25th. That morning, the swell jumps to 5ft from the SSW, with a period of 15 seconds, packing a solid moderate wave energy (902). The wind is a light cross-offshore breeze from the ESE, and the water is sitting at 73°F, which is about average for this time of year. That Tuesday morning is shaping up as one of the best calls in the whole outlook – clean lines, decent size, and not too much wind to mess it up. The afternoon holds similar, just a touch smaller at 4ft.
Wednesday the 26th keeps the fun going, with 4ft SSW swell and long 15-second periods. In the afternoon, the wind actually turns offshore from the ENE, so it’ll be clean and lined up nicely.
Thursday the 27th morning is still surfable at 3ft, but it’s fading, and by the afternoon, it’s gone again. The weekend that follows has some small, weak swell but the wind is cross or cross-off, so conditions are ordinary. Nothing to get excited about.
Into the second week, from Monday the 31st of August right through, it’s mostly small and choppy, with poor conditions. There is a bit of a pulse on Tuesday the 1st of September, but the wind is onshore or cross-onshore, so it's messy. The standout window is definitely Tuesday the 25th and Wednesday the 26th of August.
For Nera Rivermouth itself, it’s a sheltered river and beach setup, which explains why the swell has to be just right. It’s an inconsistent spot, so when it does fire, it’s a treat. The break is ideal for beginners with the smaller stuff, but that 5ft on the 25th is pushing the limit for learning. The break can get busy sometimes, so you might find a few others with the same idea.
The only real standout in this entire 16-day run is the morning of Tuesday the 25th of August at Nera Rivermouth. Get in the water then.
Rusty.
