The Lowdown

Alright folks, Rusty here. Let’s talk about the only break in the hood for the next couple of weeks: the Nera Rivermouth. It’s a sheltered river and beach spot, so it doesn’t need a big ocean to work, but it’s inconsistent and best for beginners when it does. Water temp is about 74°, which is normal for this time of year, nothing crazy.

The forecast starts slow. Friday the 17th and Saturday the 18th have small, clean waves. Friday morning gives us 3ft SSW swell with a 12-second period, and a light offshore breeze from the NE. It’s surfable but nothing special. Saturday picks up. Morning has 3ft SSW swell with a long 17-second period, and the combined energy hits 523 (moderate). Wind is light offshore, so it’s clean. By Saturday afternoon, we’re looking at 3ft SSW swell, still 17 seconds, and energy bumps to 624. That’s the best of the early window – clean, lined up, and not too crowded, though it can get a few people here sometimes.

Sunday the 19th is a weird one. Morning gets hammered by heavy rain and a cross-shore breeze, so forget it. But Sunday afternoon? That’s the standout. The swell holds at 4ft from the SSW, period jumps to a very long 21 seconds, and the combined energy rockets to 1267 (strong). The wind goes glassy – dead calm – so the river mouth will be like a mirror. That’s the session to circle. Just remember, a 21-second period can make waves a bit straight at beach breaks, but the river mouth handles it well.

Monday the 20th morning is glassy again with 3ft SSW swell and 18 seconds, but energy drops to 688. Still a nice paddle. After that, it’s a long dry spell. From Tuesday the 21st all the way to Wednesday the 29th, the wind goes mostly cross-shore or cross-onshore, often moderate to fresh, and the swell quality tanks. Lots of chop, poor conditions, and some days with barely any energy. You’re looking at a solid 8-day gap with nothing worth paddling for.

Then the window flickers back to life. Thursday the 30th morning offers 3ft from the SSW, 17 seconds, and clean conditions with a light cross-offshore breeze. Energy is 511 (moderate) – surfable, but not a standout. The real comeback is Friday the 31st. Morning brings 5ft SSW swell with 12 seconds and 598 energy, clean with a cross-offshore breeze. By Friday afternoon, the wind shifts to offshore from the NE, 15 km/h, and the swell solidifies at 5ft, dropping to an 11-second period. Energy sits at 574. That’s a proper session for confident beginners to intermediates – clean, offshore, and a decent size.

Saturday the 1st of August keeps the offshore flow going, with 4ft in the morning and 5ft in the afternoon, but the period drops to 10 seconds, so it’s a bit more junky. Still rideable and clean.

Look, if you’re in the area, the Sunday the 19th afternoon glass-off is the one to hold out for. The Friday the 31st afternoon is your backup. Other than that, it’s a waiting game.

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.
