Alright, Rusty here. Let's have a look at what's on offer for the next couple of weeks.
To be honest, it's a tough stretch for Nera Rivermouth (a sheltered river-and-beach setup). The opener on the 4th of July is a real non-starter – we're talking tiny 0.7ft SSW swell with cross-shore winds and a combined wave energy of just 23. The water's sitting at about 75°F, which is about average for this time of year, but it doesn't help when there are no waves to ride.
We drag through a bunch of days with poor surf and cross-onshore or cross winds. The swell tries to lift a bit around the 6th and 7th of July, hitting 4ft on the afternoon of the 6th and blowing up to 10ft by the afternoon of the 7th (combined energy of 4437 – strong stuff). But it's all cross-onshore and choppy, and at over 8ft, that's experts-only, messy territory, not worth the paddle out. It goes dead flat again on the 8th.
There's a long gap with next to nothing worthwhile. A tiny pulse of 2ft appears on the 11th, but it's crossed-up. The 14th of July morning actually goes glassy with a 1.0ft SSW swell (energy of 36), but it's just too small to bother with.
The only real chance to get excited comes on the 17th of July. Friday morning shows a clean 3ft SSW swell with a nice long 18-second period. The wind is a light cross-offshore breeze from the east at just 3 mph, meaning clean conditions. Combined energy is a solid 772 (moderate energy). For a spot that's normally inconsistent and sheltered, this is a real standout. The afternoon holds a 4ft swell with a 17-second period too, but it's a touch crossed-up. Still, the morning of the 17th is your best bet – a bit of a long-range promise, so keep an eye on it.
The 18th of July morning goes glassy again but flat, and the afternoon brings a 5ft SSW groundswell (15-second period) with light cross winds, but it's only a marginal call. After that, the wind picks up and it gets choppy again.
So, bottom line: a long quiet run with one standout window on the 17th of July morning. It's a rare, inconsistent spot when it does fire, so if you're keen, aim for that Friday glass-off.
Rusty.

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.
