Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s have a look at what Nera Rivermouth has got cookin’ for us over the next couple of weeks. Honestly, it’s a bit of a tough stretch. This is a sheltered, inconsistent river-and-beach setup, and the incoming swell is mostly coming from the SSW, which isn't its favourite direction. The water temp is sitting about average for this time of year.
We kick things off on Tuesday the 7th of July, but don't get too excited. There’s a solid 8 ft to 10 ft of SSW swell running, pushed in by a moderate cross-onshore breeze. The wave energy is massive (3935 and 4272 in the brackets), but with a cross-onshore wind and a 14 to 16-second period, it’s just gonna be a messy, choppy wall. The size is well over 8 ft, so this is expert-only, and even then, the quality is poor. The river mouth might be handling it, but it’s not gonna be pretty.
Wednesday the 8th is more of the same story – 10 ft of SSW swell (3400 and 2863 energy) but still with that cross-onshore breeze from the S. It’s marginal at best, and still only for the big-wave crew.
A real downer sets in from Thursday the 9th onwards. The swell drops off a cliff, and we run into a long stretch of flat to tiny, weak surf. From Thursday afternoon through to Tuesday the 22nd of July, the wave heights barely get above 3 ft, most days hanging around 0.7 ft to 2 ft. The energy readings are mostly in the double digits to low triple digits (between 17 and 450), which tells you there’s just nothing doing. Winds are a mix of light to moderate cross-shore breezes, which would be clean, but there’s no swell to push them around.
There is a glimmer on the horizon, though. If you’re patient, check out Wednesday morning, the 15th of July. We get a light ESE cross-offshore wind and a small 2 ft SSW groundswell with a long 16-second period. It’s only got 227 units of energy, so it’s tiny, but with clean conditions, the river mouth might offer a fun little wave for the longboard or a foiler. It’s the best of a bad bunch, but I wouldn’t paddle out expecting anything meaty.
The rest of the forecast is more of the same – tiny surf and ordinary conditions. On Saturday the 18th of July morning, we see a spike of 6 ft from the SSW (1432 energy) but it’s ruined by a 16 mph cross-onshore wind, creating a lumpy, choppy mess. Not worth the wet suit. For a sheltered spot that’s rarely consistent, this kind of multi-week lull is pretty normal. But you know how it goes – soon as you think it’s dead, a new groundswell shows up.
Keep your eyes on that Wednesday the 15th for a sneaky glassy session. Otherwise, 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.
