Alright, Rusty here. Let's have a look at what's on the cards for the Nera Rivermouth.
Right off the bat, the first few days are a write-off. We’ve got a solid but messy 10-foot swell from the SSW on Wednesday the 8th of July, but that cross-on shore wind is just going to chop it to bits. The combined energy is powerful, around 3400, but it’s a no-go for a paddle. It’d be more of a kitesurfer’s window if anything. After that, the swell just drops off a cliff, leaving us with tiny, weak waves for nearly a week.
The first real glimmer of hope doesn't come until Sunday the 12th of July. It’s still small, only 1 feet from the SSW, but we get a glassy morning. The combined energy is a modest 207, so it’s weak, but the clean conditions might give you a few fun little rollers if you’re on a log. It’s a beginner-friendly spot anyway, and crowds are sometimes a thing here, so don’t expect much company on a day this small.
We get another quiet spell, but then things start looking up. The standout window is Thursday the 16th through the morning of Friday the 17th of July. On Thursday morning, we’ve got 3 feet of SSW swell with a very long 18-second period and clean offshore winds from the NNE. The energy is building to a solid 469. That long period groundswell will wrap nicely into this river mouth setup. Thursday afternoon gets even better: 3 feet from the SSW, glassy conditions, energy at 545. Friday morning carries that magic with another glassy session and 3-foot waves. It’s only just above beginner-friendly size and will be super clean. If you can pick the right bank on this inconsistent spot, you’ll be in for a treat. That’s the best on offer.
After that, the wind swings onshore again on Friday afternoon and stays messy. There’s a bump in size to 6 feet on Saturday the 18th, but the onshore wind makes it a choppy mess. A few cleaner days trickle in around Tuesday the 21st, with small, clean waves in the afternoons, but nothing that lights a fire.
So, to sum it up: sit tight through the first week of July chaos and the flat spell, and then nail those glassy windows on Thursday the 16th and Friday the 17th. That’s your best bet. The long-range stuff around the 21st is promising but less certain, so keep an eye on it.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Nera Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
