The Lowdown
Alright, Rusty here again. Let’s break down the same outlook for Nera Rivermouth, but in feet and miles.
This 16-day window is a tough one. There’s a real dry spell at the start. The first proper chance to get wet won’t be until Thursday afternoon, July 30th. After that, there’s a long stretch of flat, windy, or just plain messy conditions that’ll test your patience. The water temp is sitting at 73°F, which is pretty much bang on average for this time of year.
The best bet, and the only real standout, is Friday morning, July 31st. The swell is coming from the SSW at about 3 ft, with a nice long period of 14 seconds – that’s a proper groundswell, full of energy. The wind is glassy, just a light ESE breeze at 3 mph, which means the surface will be like a mirror. The combined energy is moderate, sitting at 236. For a river and beach setup, that long period can make things a bit straight, but the glassy conditions will make it feel like a different spot. It’s a beginner-friendly wave, but you can expect company – crowds are sometimes an issue here.
The Saturday morning, August 1st, has a bit more size at 3 ft from the SSW, but the wind is a fresh 19 mph cross-shore from the SSE, and it’s got a light rain on it. The energy is solid at 358, but that wind will chop it up real quick. It’s not going to be a good look.
After that, we hit a proper dead zone. From Sunday, August 2nd, right through to the end of the first week, there’s virtually nothing. You’ll see a few small pulses around the 4th and 5th of August, with 3 ft from the SSW and strong energy (up to 774 on the morning of the 4th), but the wind is cross-shore and the wave comment is poor. It’s just not coming together.
The second week is a bit of a mixed bag. The morning of Friday, August 7th, has another glassy moment with 3 ft from the SSW and a 12-second period, but the energy is lower. Then Saturday morning, August 8th, has a similar setup with 3 ft and glassy wind, but again, it’s not a standout. The rest of the second week is tiny, with lots of onshore wind and cross-chop. The 14th of August shows a bit of a bump with 3 ft from the SW and fresh 19 mph cross-onshore winds, but that’s just a messy, lumpy mess.
So, to sum it up: the only time you should be making a plan is for the Friday morning, July 31st. That glassy window with the long-period groundswell is the jewel in the crown. The rest is 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.
