The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s shaping up on the Nera Rivermouth over the next couple of weeks. I gotta be straight with you – it’s a rough start. We’re looking at a long stretch of pretty ordinary conditions for the first week, so don’t expect much.
We kick off Sunday the 30th with a weak, messy 5ft swell from the SSW, but that 12 mph cross-onshore wind is just chopping it all up. The combined energy is moderate at 582, but it’s a no-go. It’s mostly small, cross-shore chop through Monday and Tuesday, with a tiny pulse of short-period, wind-affected swell on Tuesday that’s only 4ft from the SE with a 6-second period – that’s just wind slop. The water temp is sitting around 73°, which is about normal for this time of year, so that’s not your problem.
We’ve got a gap of several days here with nothing worth paddling out for. The first real chance comes on Thursday, September 3rd. The morning’s a bit marginal with a light cross-shore breeze and a 5ft SSW swell, but the energy is picking up to 703. The afternoon is cleaner with a cross-offshore breeze, and the swell eases to 4ft from the SSW with a 13-second period, giving it a bit more shape. The combined energy is still solid at 500. This is the best of a weak bunch, but it’s still only a “marginal” call – you might get a few fun ones if you pick your tide.
Honestly, the standout window is the following weekend. Sunday, September 6th, is looking like the best on offer. The morning has a light NNE cross-offshore breeze, clean conditions, and a 4ft SSW swell with a 16-second period. That’s a proper groundswell, and the energy is strong at 817. The afternoon gets even better – glassy conditions with a 4ft SSW swell, 14-second period, and a combined energy of 697. This is when you want to be there. Nera Rivermouth is a sheltered, inconsistent spot, so when it lines up like this, it’s a treat. Just keep in mind the crowds can be around sometimes.
The following week stays on the small side, with a few clean mornings but nothing with much punch. Monday the 7th is a bit cross-shore and marginal. The real last chance for a decent session comes on Sunday, September 13th, with a clean cross-offshore breeze, and a 4ft SSW swell with a 16-second period, giving you a combined energy of 644. It’s small, but it’ll be clean.
So, to wrap it up: the first week is a write-off. Thursday the 3rd is your only real chance in that first block, but it’s not a classic. The real standout is Sunday, September 6th – glassy, clean, and a solid swell. After that, conditions are clean but small. Get it while you can.
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.
