The Lowdown

Alright folks, Rusty here. Let's have a chat about what's on the cards for the Nera Rivermouth stretch.

Look, I'm gonna level with you straight up. This 16-day window is a tough one to call, and honestly, it's looking pretty flat and frustrating for most of it. We've got a real stretch of poor conditions ahead, so don't be holding your breath for any magic sessions in the near future. The water temp is sitting at a pleasant 74°, which is bang on average for July, so at least you won't be freezing while you're sitting there waiting for nothing. The first real chance we see of anything is a spike in energy, but it's a messy one.

Starting off this Friday, the 24th of July, we've got tiny, weak waves at 2 ft and a period of 13 seconds. It's glassy in the morning, which is a tease, but wave energy is a paltry 95. Saturday the 25th is a write-off. Sunday the 26th is where things get interesting, but not in a good way for paddle surfing. By the afternoon, a swell jumps to 8 ft with a 14 second period coming from the SSW. The combined energy rockets up to a massive 2436 – that's serious power. But it's cross-shore at 12 mph, and with that size and period on a river and beach setup? That's going to be a messy, dangerous closeout. Honestly, this looks way more appealing for a kite surfer than someone with a shortboard. Monday the 27th isn't much better, still cross-shore and tricky at 6 ft.

We then hit a long, dry spell. Through the end of July and into the first week of August, it’s a wasteland of cross and onshore winds with tiny, weak surf. The only slight glimmer comes on Thursday the 30th of July morning – a tiny 1 ft swell with a very long 16-second period and a combined energy of 190. It’s glassy, so the surface will be perfect, but it's just too small to do anything with.

Looking way ahead, there is one event that grabs your attention. On Saturday, the 8th of August, there's a bump. We're looking at 5 ft to 5 ft swell from the SSW with a very long 18 to 19 second period. That's proper groundswell energy, and with a combined energy of 1696, it’s got some punch. Now, at 5 ft to 5 ft, it's not too big for a confident surfer. The long period means the wave shape should be good for a river mouth, but it also means longer lulls between sets. The catch is the wind is forecast from the SE at 9-12 mph, which will put a cross-shore chop on it. It’s a long way out so don't hold me to it yet, but it’s the only thing on the horizon that might be worth a paddle. It’s a marginal call, but it’s the best we’ve got in this entire sheet.

The rest of that second week just fizzles out into onshore slop. So, store the boards, clean the wax, and check back with me later. The surf gods are not smiling on Nera right now.

Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
