Alright folks, Rusty here. Let's have a look at what Nera Rivermouth has got cookin' for us over the next couple of weeks.

Right off the bat, I gotta be straight with you – it's a long, flat wait ahead. The first week and a half is pretty much a write-off for any proper paddling. You'll see tiny dribbles of swell here and there, but with the wind mostly cross or cross-onshore, it's just gonna be choppy and messy. Not worth getting the wax out for. There's a big gap of days with nothing to recommend until we get towards the end of the second week.

The real action, if you can call it that, doesn't show up until around Saturday the 18th of July. The swell starts to kick up proper, with a solid 10ft to 12ft SSW groundswell pushing in over the weekend. The combined energy readings are into the thousands – 4543 on the Saturday morning, hitting a massive 5409 on the afternoon – so there's plenty of power behind it. That's proper, solid stuff. The period hanging around 16 seconds means it's a long-period groundswell, which for a river-mouth setup like this can be okay, giving those longer lulls between sets. But with the wind staying cross-shore, it won't be pure perfection. The conditions are called 'marginal' and given the size is well over 8ft, this is strictly for the experienced crew only. Beginners, stay well clear.

Then we roll into Sunday the 19th. Swell backs down a touch to around 8ft and 8ft from the SSW, still packing plenty of punch – energy readings of 2402 and 1804 – but the wind goes light and variable. That'll keep the surface reasonably tidy. Still big, still powerful, still only for the experts.

So the one true standout here, the one you gotta circle on your calendar, is Saturday the 18th of July, early morning. That's when the biggest and most powerful swell arrives with the cleanest conditions of that window. It's a beast, but if you've got the skills and the board for it, that's your moment. The water is sitting at about 75°, which is pretty average for this time of year, so no worries there.

For everyone else, grab a coffee and wait. This break is inconsistent at the best of times, and this particular run is a long one. Forecasts can always change, but as it stands, it's a waiting game.

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.
