The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up at Nera Rivermouth.
We’re starting off with a pretty quiet stretch. The first few days have some tiny waves, but nothing you’d bother paddling out for. The water is about 74°, which is pretty normal for this time of year.
Tuesday the 21st has some knee-high swell, but it’s messy with a cross-shore wind. Wednesday the 22nd looks cleaner with a cross-offshore breeze, but the swell just disappears. Thursday and Friday are glassy, but flat. There’s a real gap of nearly a week with no surf worth mentioning.
The first real pulse shows up on Sunday the 26th. The morning swell hits about 4ft from the SSW, but it’s lumpy and cross-shore. The afternoon gets bigger – 8ft from the SSW, with a 14-second period. That’s a ton of energy (2158) and it’s powerful, but at that size, it’s only for the experts. The wind is still cross-shore, so it’s not going to be perfect. This is a heavy river-mouth wave, and it’ll be a real challenge.
Monday the 27th holds that size, around 6ft, with a bit gentler breeze. Still a solid swell, but the conditions are just okay.
Now for the standout. The best window by far is the end of the first week into the start of the second. On Friday the 31st, we start to see the promise. The morning has a clean 3ft from the SSW with a light offshore wind from the NE. That’s a great sign. The afternoon gets better – 6ft, clean, light breeze, from the SSW. That’s a really good session.
But the real gold is Saturday, the 1st of August. The morning offers 8ft from the SSW, with a 14-second period, and the wind is light and cross-offshore. That’s a powerful groundswell, and the energy reading is 2200 – strong. This is going to be a proper, thumping wave at the rivermouth. The water will be clean, the lines will be long. For the experienced surfer, this is the one to circle. The afternoon holds the same size and quality. This is a big, clean, powerful swell, and it’s the best on offer by a long shot. The crowds are sometimes a thing here, so expect company.
Sunday the 2nd continues the run with 5ft to 6ft, clean and cross-offshore. Another solid day.
After that, the swell fades out quickly. Monday the 3rd has a tiny glassy pulse, but it’s small. Then we get a shift to onshore and cross-onshore winds from the 4th of August onwards, with some rain and choppy conditions. The run is over.
So, the call: the first week is a write-off except for the bigger, more challenging swell on the 26th and 27th. The true standout is the stretch from the 31st of July through the 2nd of August, with Saturday the 1st being the pick of the bunch – a powerful, clean, SSW groundswell with light winds. That’s the one to get excited about.
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.
