Yo, Rusty here, checking in on Nera Rivermouth. This is a river and beach setup, a bit sheltered, so it needs the right swell to turn on. Water temp is pretty average for the season, nothing wild.
Let's be real – the first week-plus is grim. From Thursday 9th through Monday 13th, it's a whole lot of nothing. Tiny waves, messy onshore winds, and a lot of frustration. The combined energy is low, in the double digits and weak (39, 66). You'd be chasing ankle-biters.
We get a tiny blip on Sunday 12th morning. Glassy water, which is a huge plus, but the swell is only 1ft. The combined energy hits 235 (moderate), enough to make it surfable but nothing to write home about. It's a "get wet" session, not a standout.
Things start to get interesting on Wednesday 15th morning. Swell picks up to 3ft from the SSW with a 12-second period, and we get clean, cross-offshore wind. The energy is 290 (moderate). It's the first day that looks genuinely fun.
But the real show is Thursday 16th and Friday 17th. Thursday morning is my pick. Glassy and calm, with a clean 3ft SSW swell and a long 19-second period. The combined energy jumps to 625 (moderate-strong). That long period is going to make the river mouth wave a lot of fun, with great shape and longer lulls between sets.
Friday 17th morning is also a winner – glassy again with a 4ft SSW swell, a 16-second period, and strong energy at 931. But Friday afternoon turns heavy. The swell pumps up to 10ft. That is expert only. Powerful, big, and not for the faint of heart.
After that peak, it's back to the struggle. Saturday 18th is blown out and lumpy with 8ft waves, only for the strong. From Sunday 19th onward, it's just small, choppy, and not worth the drive.
So, for the best on offer: Thursday 16th July morning. That's the one. Friday morning is a close second. Everything else is a waiting game.
Rusty.

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.
