The Lowdown
G’day, Rusty here. Let’s be straight up: this 16-day window is a tough one for Nera Rivermouth. We’ve got a long, dry spell ahead with hardly anything worth paddling out for. The first real suggestion of surf doesn’t show up until Tuesday the 25th of August, and even then, it’s nothing to write home about. Before that, we’re looking at days of flat, weak conditions or tiny, messy waves with no energy. Thursday the 20th through to Monday the 24th is pretty much a write-off – you’ll be better off waxing your board and staring at the ceiling.
The best chance you’ll get is around Tuesday the 25th and Wednesday the 26th. Tuesday afternoon sees a modest bump: swell around 4 ft from the SSW with a period of 15 seconds, which is a long-period groundswell. That’s enough to get some shape into the waves, especially at a river mouth setup like this, where those longer lines tend to hold up better. The combined energy sits at 485 (moderate). Wind is a cross-offshore from the ESE at 12 mph, so it’ll be pretty clean. Wednesday morning is just as good – 3 ft SSW swell, 15 seconds, with lighter cross-off winds at 6 mph. That’s your pick of the fortnight. These days are for surfers who know the break; the inconsistent nature of the spot means you’ll need some patience, but when the sets come through, they’ll be worth it. Crowds can show up sometimes, so keep an eye out.
After that, it fades fast. Thursday the 27th has some glassy moments in the morning with 3 ft swell, but the energy drops (326) and the wind shifts cross-shore by the arvo, killing the quality. From Friday the 28th right through to the end of the window, it’s mostly small, weak, and choppy. Water temp is around 73°F – pretty average for this time of year, nothing wild. The swell direction is consistently from the SSW, which is the optimum direction for this sheltered spot, so that’s one positive, but without size and clean winds, it doesn’t matter much. Short story: if you’re free on Tuesday the 25th or Wednesday the 26th, get out there. Otherwise, it’s a waiting game. Maybe the kites will have a laugh on the windier days, but for paddle surfing, this run is mostly a bust.
Rusty.

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.
