The Lowdown
G’day, Rusty here. Look, I’m gonna be straight with you – this is a tough run for Nera Rivermouth. We’ve got a long, quiet patch ahead before anything remotely worth paddling out for shows up. The first decent surf doesn’t arrive until Monday, July 27, and even then, it’s a bit of a mixed bag. The water’s sitting at 74°, right around average for this time of year, so no wetsuit drama.
Right now, through Tuesday, July 21, into the weekend, it’s flat or near-flat. Tuesday morning saw a tiny 3ft swell from the SSW with a short 14-second period, but the cross-shore wind made it choppy and messy. The combined energy was only 430, so weak. After that, it drops right off. Wednesday and Thursday are basically flat with clean winds but no swell to speak of. Friday, Saturday, and Sunday offer nothing – just a few tiny 1.0ft to 1ft pulses that aren’t worth your time. The break is sheltered and inconsistent, so this kind of blank run isn’t unusual here.
Our first real chance comes Monday, July 27. The morning shows a 5ft swell from the SSW with a 12-second period, and the combined energy jumps to 718 – moderate. But the wind is cross-shore at 12 mph, so it’ll be a bit lumpy. By Monday afternoon, the swell bumps up to 6ft, period stretches to 14 seconds, and energy hits 1039 (strong). Still, the wind is cross-shore, and the conditions are only marginal. This is a river-and-beach setup, so that longer period (14 seconds) might make it a bit straight and fat on the beach section, but the river mouth could offer a better line. It’s not a standout, but it’s the first surfable day.
Tuesday, July 28, is your best bet early on. The morning sees a 5ft swell from the SSW, 12-second period, and 624 energy. The wind is light from the SE at 6 mph, cross-offshore, and the forecast says “clean.” That’s about as good as it gets for this spot. The swell is just under 5ft, so it’s manageable for a confident beginner, but at 5ft it’s pushing the limit. The afternoon drops off a bit with cross-shore winds and a 5ft swell, so aim for the morning session. Crowds are possible here, so you might have some company.
After that, Wednesday and Thursday return to small, messy junk. Friday, July 31, brings a 6ft swell from the SSW with an 11-second period, and energy is 1649 – strong. But the wind is cross-shore at 9 mph, creating a cross-chop, and the conditions are only marginal. At 6ft, this is getting a bit too big for beginners, but it’s still fine for intermediates. The period is short enough that it won’t be too straight on the beach.
Moving into the first week of August, Saturday, August 1, holds 7ft to 7ft swell from the SSW, 12-13 second period, and energy around 1465-1568. That’s strong swell, but the wind is cross-shore and the conditions are marginal. At over 7ft, this is for experienced surfers only. The break is inconsistent, so you’ll be waiting for sets. Sunday, August 2, drops to 4ft in the morning – still marginal, but the wind is gentle from the SE at 9 mph, making for a more pleasant session. The combined energy is 890, moderate.
Honestly, the standout in this whole outlook is Tuesday, July 28 morning. That’s the cleanest window we get, with cross-offshore wind and a solid 5ft groundswell. It’s not huge, but it’s clean. After that, the July 31 to August 1 window has more size, but the wind is messy. If you’re an expert, that might be worth a look, but for most of us, Tuesday morning is the pick.
So, for the next 16 days, it’s mostly flat or marginal. The best call is Tuesday, July 28 morning – clean, 5ft SSW swell, light cross-offshore wind. Don’t expect much else until the very end of the period.
Rusty.

Information about the Nera Rivermouth Surf forecast
The above surf forecast table for Nera Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Nera Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Nera Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
