The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Nera Rivermouth over the next couple of weeks.
It's a slow start, no doubt about it. We've got a bit of a wait on our hands. The first real chance of a wave doesn't pop up until the morning of Tuesday the 4th of August. That's a few days of flat or near-flat conditions to get through. The water temp is sitting right around 73°, which is pretty much bang on average for this time of year, so no surprises there.
Now, Tuesday morning the 4th is our one true standout. Nera Rivermouth is a sheltered river and beach set-up, and it's inconsistent, so you have to pick your moments. Tuesday morning looks like that moment. We've got a clean 3ft of SSW groundswell rolling in with a long 19-second period, pushing moderate wave energy (402). The wind is a light cross-offshore from the ESE at 9 mph, which is going to keep the surface glassy. The optimum swell direction here is SW, and the SSW direction is close enough to be working well. This is the session to aim for, no question.
The rest of the first week is a bit of a struggle. Tuesday afternoon the wind swings and the surf gets a cross-chop, and it's a downhill slide from there. The swell drops right off through Wednesday and Thursday, and while we get some clean offshore winds on Friday and Saturday the 7th and 8th, the swell is tiny – 0.7ft – and just not worth paddling out for.
Then we hit a proper dead zone. From Sunday the 9th right through to Friday the 14th of August, it's a string of poor surf conditions with minimal swell and ugly cross-shore winds. Nothing to get excited about.
Now, here's where it gets interesting, but it's a long-range call so keep your expectations in check. Saturday the 15th of August, we see a big jump in swell. The morning shows 7ft of SSW groundswell at a 15-second period, with a massive energy reading of 1819. That's a serious amount of water moving. The problem is the wind is cross-shore at 9 mph, keeping it a bit lumpy. The forecast notes marginal surf conditions, likely due to tide, and with that size, it's going to be one for the experienced crew only. The 8ft+ mark is for experts, and while Saturday morning is 7ft, the afternoon pushes to 7ft. Sunday the 16th drops a bit to 5ft, but the wind picks up again. Monday the 17th has a 7ft SSW swell but with strong cross-shore winds of 22 mph, which is going to be ugly and more suited to a kite than a surfboard.
So, to wrap it up: your best bet is Tuesday morning the 4th of August for a clean, fun-sized wave. The big swell around the 15th is worth watching, but it's a long way out and the winds look tricky.
Rusty, signing off.

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.
