The Lowdown
Alright, Rusty here, breakin’ it down for Nera Rivermouth. This is a sheltered river-and-beach spot, best when the swell comes from the southwest. It’s a beginner-friendly wave, but it breaks inconsistently, so you gotta pick your days. Water temp is 73°, right on the money for the season.
The start is a bust. Saturday the 5th and Sunday the 6th are total junk, so leave the board at home. The first real chance is Monday the 7th, but it’s tiny. Morning sees a 3ft swell from the SSW with clean offshore wind out of the SW. That’s your one clean window, but the energy is moderate (405). The swell period is 13 seconds, so it’ll have a little shape. After that, the wind goes onshore and the surf disappears through Tuesday and Wednesday.
We’re looking at a long dry stretch from the 7th to the 11th. Thursday and Friday are a waste with barely any swell and fresh cross-shore winds at 15-18 mph. The energy levels are weak to moderate, but it’s just poor surf.
The first real standout is Saturday the 12th. A big pulse of SSW swell hits 10ft in the morning with a 17-second period. That’s a long-period groundswell, and at a river mouth it can be a bit straighter, but it’s got some power. The energy is through the roof at 5018 – strong stuff. The catch is a fresh cross-shore wind out of the SE at 18 mph, which will make it lumpy and choppy. At 10ft, it’s expert-only. It’s a marginal call because of the wind, but if you can handle the chop, this is the biggest wave of the forecast. Sunday the 13th drops to about 6ft, but the cross-shore wind is still there, keeping it messy.
From the 14th to the 17th, it’s flat or tiny. The morning of the 16th goes glassy with a light offshore breeze, but the swell is a pathetic 1ft. Not even worth wetsuiting up for.
The last promising window is Friday the 18th through Saturday the 19th. Friday afternoon brings a 3-4ft SSW swell with a very long 21-second period and moderate energy (1160). The wind is cross-shore, so it’s not clean, but the long period will give it some punch. Saturday the 19th has serious size again – 11-12ft in the morning and 10ft in the afternoon, both from the SSW with 16-17 second periods. Energy is extreme (6552 in the morning). The wind is cross-shore to cross-onshore, making it a messy beast for experts only. If the wind would just cooperate, it’d be epic.
For beginners, this forecast is a no-go. For the seasoned crew, Saturday the 12th and the 19th are the big days, even with the chop. Given the spot’s inconsistent nature, this patchy run is pretty normal. Stay patient.
Rusty out.

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.

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.
