The Lowdown

G’day surfers, Rusty here. Let’s break down the next couple of weeks for Nera Rivermouth. To put it plain, it’s a pretty quiet stretch with not much to get stoked about. There’s a big gap of poor conditions ahead, so you’ll need some patience.

Starting from now, the forecast shows almost nothing worth paddling out for days.

Tuesday morning the 11th through to Thursday morning the 15th has tiny, weak swell and poor surf conditions. Swell heights barely reach 2 ft, with periods all over the place – some long-period groundswell up to 19 seconds, but combined wave energy is weak, mostly under 100. Winds are light or glassy at times, but the waves aren’t there. Water temp is pretty average for this time of year, nothing unusual.

Thursday afternoon the 13th brings a little pulse – swell hits 3 ft from the SW with a 13-second period, and combined energy bumps to 272, which is moderate. Wind swings onshore, though, making it messy and not surfable.

Friday the 14th and Saturday the 15th see a bit more size – swell around 4 ft to 4 ft – but onshore and cross-shore winds keep it choppy and poor. Combined energy sits between 329 and 431, but quality is no good.

Sunday the 16th through Monday the 17th has swell around 3 ft to 3 ft with long-period energy from the SSW, but cross-shore winds and poor conditions ruin it.

The only real window comes Tuesday the 18th. The morning is still marginal – 3 ft swell with 15-second period and combined energy of 405, but cross-shore. The afternoon offers 3 ft swell from the SSW, 14-second period, and combined energy of 246 (moderate). Wind goes cross-off and the surf turns clean. It’s surfable but very ordinary, not a standout. You could snag a few, but it’s nothing special.

After that, it drops hard. From Wednesday the 19th onward, swell plummets to 0.7 ft to 1 ft, mostly poor conditions. There’s a short spell on Friday the 21st with glassy wind, but swell is a puny 0.7 ft, so it’s flat.

From the 22nd through to the 26th of August, there’s almost no swell – heights zero or tiny, combined energy barely a blip. Winds stay onshore or cross-shore, so it’s a dead end.

The one time you might get wet is Tuesday afternoon the 18th at Nera Rivermouth. It’s the only clean-ish surf, but the quality is ordinary, and the spot is inconsistent and sheltered, so crowds are possible when it does break. It’s a beginner-friendly wave, but honestly, don’t get your hopes up.

Best bet: if you’re keen, try Tuesday the 18th afternoon for a few small ones, but otherwise, this is a long, quiet run.

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.
