The Lowdown
Righto, Rusty here again. Let’s run through the same outlook but in feet and miles per hour, for those who think that way.
The first hint of a rideable wave at Nera Rivermouth isn’t until Wednesday, July 29th. Monday and Tuesday the 27th and 28th have some swell – about 6ft from the SSW – but that 12 mph cross-shore wind has it all chopped out. Forget it. Wednesday morning is clean but tiny, barely a foot from the SSW. The afternoon picks up a little to 3ft from the SSW, with a 10-second period and a light cross-off breeze around 6 mph. It’s just "surfable", combined energy of 121. Not much to write home about.
Thursday the 30th starts glassy – dead calm – with a 1ft SSW swell but a very long 16-second period. Combined energy of 170. The long period means it might break a bit straight at this river mouth, plus it’s so small you’ll be working hard for it. Not a standout morning. From Friday the 31st through the weekend, we get small onshore waves with rain and chop. Saturday and Sunday the 1st and 2nd of August see swell around 3ft from the SSW, but cross-shore winds around 16 mph keep it messy – combined energy hits 700 on Saturday morning but the quality is poor.
The first week of August is mostly flat and poor. A small pulse on Friday the 7th gives us 3ft from the SSW, 12-second period, and clean offshore winds around 6 mph. Combined energy of 286 – it’s surfable. Saturday the 8th is similar with glassy conditions in the morning but still just 3ft.
The best window falls on Sunday the 9th of August afternoon. We get 3ft from the SSW, a 12-second period, and glassy winds. The combined energy hits 396, the highest we see in the whole 16 days. That’s your pick. It’s not big, but it’s clean. The rest of the run into Monday and Tuesday the 10th and 11th drops back into tiny, clean but barely rideable waves.
Nera Rivermouth is an inconsistent, sheltered spot, and this is a typical quiet stretch for the area. No big swells, no hero moments. But that Sunday afternoon could give you a few clean ones if you’re keen. Forecasts can change, so don’t give up entirely.
Rusty.

Information about the Nera Rivermouth Surf forecast

A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu.

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.
