The Lowdown
Alright, Rusty here – keeping it in feet and miles per hour for you. From August 11th through the 26th, Nera Rivermouth is flat-out quiet. This sheltered river and beach spot is inconsistent even when it’s working, and this 16-day run is a long stretch of barely any surf worth mentioning.
Tuesday the 11th through Sunday the 16th: all poor surf. Swell runs from a pathetic 0.7 ft up to a best of 4 ft on Saturday morning, but that comes with a messy cross-shore breeze at 16 mph, so it’s choppy and ragged. Wave energy tops out at 759 on Sunday the 16th morning, but that’s still just moderate, and the 16-second period from the SSW will just make it close out at a beach break. No clean, glassy windows in this stretch.
Monday the 17th gets fresh cross-shore winds at 19 mph and lumpy cross-chop – leave the board at home. Tuesday the 18th morning is the only semi-interesting moment: 3 ft of SSW swell with a 15-second period, gentle cross-shore breeze, and energy of 405. It’s marginal, and crowds are *sometimes* possible, so you might have it to yourself, but it’s still a far cry from good. After that, from the 19th onward, it’s back to 0.7 ft to 1 ft dribble, with clean but tiny conditions on the 20th and 21st mornings – fine for a float, not for a ride.
No standout days here. This stretch is better suited for a kite or a flat-water cruise. Forecasts can always shift, but a blank run like this is pretty standard for this protected spot. Keep your wetsuit handy and hope for a change.
Rusty.

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.
