The Lowdown
Alright folks, Rusty here. Let’s be straight with you – if you’re in the market for a decent wave over the next 16 days around Nera Rivermouth, you’re gonna have to dig deep for optimism. This is a river and beach break that’s usually a beginner-friendly, sheltered spot. At first glance, this outlook is a proper stinker. The near term is dominated by poor conditions and cross-shore winds, and there's a big gap of flatness mid-period.
Let’s kick off on Monday the 27th of July. Right out of the gate we’ve got a southerly groundswell pushing 6ft from the SSW with a period of 12-13 seconds, but the wind is a cross-shore breeze from the southeast at 12 mph. The water’s sitting at a pretty warm 73°, which is basically average for this time of year, but the combo of that cross-shore chop and a "poor surf conditions" tag means you’re better off staying on the bank. The combined swell energy is moderate (793), but looks count for nothing with that wind.
From Tuesday the 28th through Thursday the 30th of July, things drop right off. We’re looking at a flat spell Tuesday with zero swell reaching the break. Wednesday the 29th sees a tiny 1ft to 3ft SSW swell trickle in with periods of 10-12 seconds. The combined energy is weak to moderate (29 to 118). Thursday the 30th offers a cool moment – the morning is glassy with calm winds, 1ft of long-period groundswell (16 seconds), and energy hitting just 102. It’s small and clean, but honestly too small to get excited about. That glassy water is a tease.
Friday the 31st of July and Saturday the 1st of August see the swell bump up again slightly: 2ft to 4ft from the SSW with periods around 12-15 seconds. Combined energy gets up to 778 on Saturday afternoon, which is moderate. But the wind is cross-shore all the way, and on Saturday morning it’s a fresh 19 mph with rain showers, making the surf lumpy and chopped. The wave comment says it all: "poor surf conditions".
Now, brace yourselves – from Sunday the 2nd of August right through to Wednesday the 6th of August, we hit a major flat spell. Most of those days show zero combined energy. There’s a brief blip on Tuesday the 4th where we get 1ft of 19-second groundswell (long-period!), and the morning is clean with a gentle cross-offshore ESE breeze. The combined energy is moderate (204), and it’s marked as "surfable waves but very ordinary conditions." That is the best we’ve got. That’s your standout if you’re desperate for a slide, but only a single 1 out of 10 score says it all. It’s very clean but tiny.
The second week, from Thursday the 6th of August onward, is mostly tiny. A few days show 0.7ft to 3ft of swell, but periods drop right off (5-6 seconds on Thursday and Saturday) which is short-period junk. The wind does flip offshore or cross-offshore from the east-northeast side, which keeps it clean, but with combined energy rarely cracking 181, it’s just too weak.
So here’s the summary: Nera Rivermouth rarely sees proper swell to begin with, so a blank run like this isn't a huge shock. The one standout is that Tuesday morning the 4th of August. If you have a longboard and patience, that glassy 1ft, 19-second groundswell with a clean cross-offshore breeze is about as good as it gets in this stretch. Don't expect barrels; the period is so long at a river/beach setup it'll break a bit straight. Crowds are possible there sometimes, but with these conditions, you'll have it to yourself.
Otherwise, you might want to check if this setup is better for a kite than a paddle on the bigger, messier days. It’s a tough 16 days, folks.
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.
