The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up at Nera Rivermouth over the next couple of weeks.
Right off the bat, it’s a slow start. There’s no worthwhile surf to speak of until Thursday the 16th, so you’re looking at a couple of days of flatness or junk. The first real glimmer comes Thursday morning with a 3ft SSW swell, but the period is a long 16 seconds which means those waves will be holding up shape nicely off the river mouth, though the sets will be spaced out. The cross-offshore breeze keeps things clean, but the energy is moderate (368) and the conditions are described as very ordinary, so don't expect much.
Friday the 17th stays small with 3ft SSW at 12 seconds in the morning, and a proper offshore wind from the NE. That’s a clean setup for a beginner-friendly river mouth break, but again, it’s far from pumping. Saturday the 18th is where things start to get interesting. The morning brings a solid 3ft SSW swell with a long 17-second period, combined with a light cross-offshore breeze. The combined energy jumps to strong (584) and the surf report says “expect good surf conditions.” That Saturday morning window is a standout – clean lines, manageable size, and decent push for a sheltered spot.
Sunday the 19th shows a bump in swell height to 3ft, but the period drops to 14 seconds and the wind turns cross-shore, creating some chop. The energy is high (756) but the quality is marginal due to tide and wind. Not bad, but not the best of the stretch.
Monday the 20th and Tuesday the 21st are write-offs. Onshore winds and rain ruin any chance of clean surf. Wednesday the 22nd is even worse, with tiny 1ft waves and onshore wind. From the 23rd through the 25th, it’s a total dry spell – barely a ripple, strong cross-winds, and energy readings in the teens to 50s. You’d be better off doing something else.
Things finally start to look up again on Sunday morning the 26th. A tiny 1ft SSW swell at 14 seconds with light cross-offshore winds and a bit of energy (137) makes for a very ordinary session. Not worth getting excited over.
Then, Monday the 27th morning brings real promise: 3ft SSW with a long 17-second period, light cross-offshore wind, combined energy of 456 (“good surf conditions”). That’s a solid session for the rivermouth – clean, consistent enough, and not too big. Tuesday the 28th is the absolute pick of the whole outlook. The swell builds to 4ft Tuesday morning and 4ft in the afternoon, both from SSW with 17/16-second periods, light cross-offshore winds, and combined energy in the 700s. That’s strong, clean, and well-shaped – the best on offer. Wednesday the 29th morning holds up with 3ft and lighter winds, still good, but the afternoon gets choppy with a 12 mph cross-offshore.
So here’s the takeaway: if you’re looking for the best windows, lock in Saturday the 18th morning for a clean, punchy session, and then Monday the 27th morning and especially Tuesday the 28th for the standout waves of the whole period. Longer-period groundswell means the river mouth will handle it well, and the light offshore winds will keep it glassy.

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.
