The Lowdown
Alright, Rusty here. Let’s take a look at what’s shaking on the local stretch.
First off, things are pretty quiet at Nera Rivermouth for a while. The water’s sitting at about 74°, which is right around average for this time of year.
We’re looking at a bit of a dry spell to kick things off. Thursday the 23rd and Friday the 24th offer almost nothing worth paddling out for, with tiny swell and poor conditions. The first real glimmer shows up on Friday morning the 31st of July. That’s the standout of the whole outlook. We’ve got a clean 3ft SSW swell rolling in with a 16-second period, which is a lovely long groundswell. The wind is glassy from the NE, so it’s going to be smooth as butter. The combined energy is moderate at 402. This is a river and beach setup, so with that long period, it might break a bit straight, but it’s the best we’ll see. It’s a beginner-friendly size too, so it’s a good one for everyone.
Saturday the 1st of August keeps the fun going. Morning looks clean with a 3ft SSW swell, offshore NE breeze at 3 mph, and moderate energy (563). The afternoon picks up to 5ft from the same direction, still clean, and with a light cross-off wind. That afternoon session has good energy (877) and decent shape.
Then Sunday the 2nd of August is a real treat. The morning is glassy, calm wind, with a solid 6ft SSW swell and a 12-second period. That’s pushing into the more powerful range, combined energy at 861, so it’s got some punch. This is the second standout. It’s still manageable for most, but the size might be a bit much for absolute beginners. The wind is dead calm, so it’s going to be pristine.
After that, the surf drops off quickly. By Monday the 3rd of August, we’re back to tiny, weak waves with poor conditions, and it stays pretty marginal through to the end of the forecast. There’s a small uptick on the 5th and 6th, but the wind is cross-shore or cross-on, so it’s not going to be clean.
So, if you’re getting out there, aim for the morning of Friday the 31st of July or the glassy morning of Sunday the 2nd of August. Those are your best bets.
Rusty.
