The Lowdown
Alright, this is Rusty. Let’s have a look at what’s on the table for the Nera Rivermouth.
We’re kickin’ off a pretty quiet spell here. For the first week or so, it’s a bit of a bust. We’ve got a stretch from Sunday the 2nd right through to Tuesday the 11th where the waves are just too small or the conditions are messy. A lot of cross-shore wind and barely any push. You’ll see days with swell heights at zero or under 1 ft, and the combined energy is weak, well under 100 (0-96). It’s a long gap with nothing worth paddling out for.
Then things start to look a little more promising. On Wednesday the 12th morning, we start seeing some life. The swell bumps up to 2 ft from the SW with a moderate 11-second period, and the combined energy jumps to 123 – that’s moderate energy. It’s still just “surfable but ordinary” conditions though, so nothin’ to get too excited about.
Now, The real standout window shapes up for Thursday the 13th morning. We’ve got a clean 4 ft SSW groundswell with an 11-second period. The wind is a light offshore from the NNE at 6 mph. That’s clean, lined-up, and the combined energy is a solid 466. For a sheltered river-mouth spot, that’s a good little pulse. The water temp is about 73°, which is pretty average for this time of year. This is the moment to be out there. Keep in mind this break is inconsistent, so you might get some lulls between sets, but when it comes, it’s your best bet.
Further out, on Sunday the 16th morning, the swell really starts to kick. We’re talking 7 ft SSW groundswell with a long 15-second period. The combined energy is huge – 1955. The wind is a near-glass from the E, so it’ll be clean. That’s proper groundswell power. By the afternoon, it pushes to 8 ft SSW with the same long period and energy of 2749 – that’s very strong. This is expert territory for sure, especially at a river mouth, which can handle that long-period direction better. Expect excellent, powerful waves, but only for experienced surfers. Monday the 17th morning will still hold at 7 ft with a 13-second period and strong energy at 1802, before it fades off quickly.
So, for the whole outlook: there’s a big dry spell up front. The best windows for a paddle are Thursday the 13th morning for the clean shoulder-high sets, and the weekend of the 16th/17th for the bigger, more powerful groundswell – that one’s only for the crew who know what they’re doing.
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.
