The Lowdown
Alright, Rusty here. Let’s see what’s cooking.
Right off the bat, I gotta be straight with you – the next few weeks are looking pretty grim for Nera Rivermouth. This is a river and beach setup, sheltered from the swell, and it’s gonna be a long, flat spell. We’re looking at a solid run of days with no real surf on offer, from now pretty much through to the middle of the month. The first real chance of anything rideable doesn’t even show up until Wednesday the 19th of August, and even then, it’s not much to write home about.
What we’ve got is a tiny, inconsistent spot that’s best for beginners, but there’s just no energy. The first 11 days are a total write-off, with swell heights barely scraping 0.7 ft to 1.0 ft. The combined energy is weak, sitting in the single digits or low 20s. It’s all poor surf conditions. There’s a little blip of energy on the 14th and 15th of August, with the swell trying to push up to 5 ft and 5 ft from the SSW, and the combined energy jumps into the hundreds (480 and 656) – that’s moderate wave energy. But the wind is a mess, cross-shore and choppy, and the conditions are still rated as poor. The short period of 10 seconds on those days means the waves won’t have much shape, especially at a river mouth.
The one day that might get a nod is Wednesday the 19th of August. The morning shows a 2 ft SSW swell with a period of 14 seconds – that’s a longer period groundswell which is good for a river mouth, meaning some better shaped waves. The wind is light and cross-offshore, keeping it clean. The combined energy is 196, so moderate. The guidance says it’s “surfable waves but very ordinary conditions” – a score of 1 out of 10. It’s not a standout by any stretch, but it’s the only game in town. You’ll likely have the place to yourself, because it’s inconsistent and rarely breaks, so crowds are only a possibility. But honestly, bring a longboard and keep your expectations low.
The water temperature is sitting at 73°F, and the anomaly is only 0.2°F, so it’s bang on average for this time of year – no surprises there.
If you’re a kitesurfer, the setup on the 16th of August with a 5 ft SSW swell, a 15-second period, and a fresh cross-shore wind at 19 mph might look a lot more interesting than it does for paddling. The combined energy is a massive 1192, which is strong, but the cross-shore wind and the messy conditions make it a no-go for a clean paddle session.
So, to sum it up: we’ve got a long, flat start, a dodgy middle, and only one very ordinary day on the 19th of August that might, just might, give you a couple of grovelly ones. The forecasts can always change, but for now, it’s a waiting game.
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.
