The Lowdown
G’day, Rusty here, and let’s be straight – this outlook is a patience test for your local waves. There’s a long stretch of nothing much before a couple of windows appear worth paddling out for.
The first few days at Nera Rivermouth are flat or tiny with cross and cross-off breezes messing things up. Even when Friday 24th July brings a glassy morning with a little 0.5ft SSW swell, it’s still considered poor – the conditions are clean but there’s just not enough wave. Sunday 26th July brings some size – around 6ft in the morning and nearly 8ft in the afternoon – but moderate cross winds and a lumpy chop ruin it. Once it’s over 8ft, that’s for experts only and even they’ll be battling the wind.
Monday 27th July is your first real chance. The morning offers about 6ft of SSW groundswell with a good cross-off breeze from the ESE, keeping the waves clean. Combined energy is in the strong range (1179), and that brief window beats anything before it. Get out early because the afternoon gets choppy again.
Then we hit a lull. Tuesday 28th July is fresh cross winds and lumpy mess, and from that afternoon all the way through to the start of August, it’s tiny, weak, and unsatisfying – just small swell with cross chop.
But then comes the real gem. Thursday 6th August lights up. The morning shows 8ft of SSW swell from the southwest, combined energy is massive at 2629, with light offshore winds from the NNE. This is a serious groundswell with long periods over 15 seconds – powerful, clean, and perfect for the river mouth setup. It’s for experienced surfers only, but it’s the kind of morning that makes the whole wait worth it. Water temperature hovers around 74°, just a hair above average, so nothing unusual. Crowds are possible at Nera Rivermouth, but on a standout morning like this you won’t care.
To sum it up: a long dry spell, a decent but short Monday morning on the 27th July, and one absolute cracker of a morning on the 6th August. The rest is for the kite crew or taking a break.
Rusty.

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.
