Alright, Rusty here. Let’s have a look at what’s on the table for the Nera Rivermouth area over the next couple of weeks.

Honestly, mate, it’s a pretty lean stretch ahead. The forecast is showing a whole lot of nothing for the first week. We’re looking at a run of small, messy, or flat conditions from Sunday, July 12th, right through until Wednesday, July 22nd. The swell is tiny, the wind is mostly cross or cross-onshore, and the combined energy readings are weak, often under 200. It’s not going to be worth paddling out for most of that time unless you’re just desperate for a float.

The water temperature is sitting at about 74°, which is pretty standard for the time of year, so no need to worry about a wetsuit.

The first real glimmer of something surfable appears on Thursday morning, July 16th, with a 3 ft SSW swell pushing in with a 16-second period. The combined energy hits 353, which is moderate, but the wind is light and cross-off, so it’ll be clean. Still, it’s not a standout, just ordinary. The same goes for Friday, July 17th, when we get a shot of glassy conditions in the morning with a 2 ft SW swell, and again in the afternoon with 3 ft. The wind goes dead calm, so it’ll be clean, but the waves are still on the small side for most.

The pick of the entire forecast comes from a run on Saturday, July 25th, through Sunday, July 26th. On Saturday afternoon, the wind swings offshore from the NNE at 9 mph, and we get a 2 ft SSW groundswell with a 15-second period. The combined energy is 181, so it’s moderate, but that offshore wind is the key. It’ll be clean and lined up. Then Sunday morning, July 26th, is the best of the bunch: a 2 ft SSW swell with a 13-second period, a light cross-off breeze from the north, and the combined energy sits at 178. It’s not huge, but it’s clean, and the break is a river and beach setup, so it can handle that direction. Note that this spot is inconsistent and sheltered, so it needs the right push. Given the crowds are listed as “sometimes,” you might not have to fight for a wave, but don’t bank on it being empty.

For the late period, Monday morning, July 27th, has a glassy 1 ft SW swell with a long 17-second period, but it’s pretty small. Still, if you’re keen on a longboard and a quiet paddle, that’s your window.

Overall, the best bet is the Saturday afternoon and Sunday morning window on July 25th and 26th. The 2 ft to 2 ft SSW swell, with offshore or light wind, will offer the cleanest, most rideable waves of the fortnight. The long period (15-13 seconds) means the sets will be spaced out, which is good for the paddle out, but it’s a point break/river setup, so it should hold shape well. The energy is moderate, so don’t expect a big punch, but it’ll be fun.

Outside of that, it’s either flat, choppy, or too small to bother with. The gap from July 12th to July 22nd is a real dry spell, so don’t get your hopes up if you’re planning a trip.

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.
