The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple weeks at our little stretch.

Right off the bat, I gotta be straight with ya: this is gonna be a tough watch. There’s no surf to get excited about for a long, long time. The first real chance of anything even vaguely surfable doesn’t show up until Monday the 17th of August, and even then it’s described as marginal. Before that, from now all the way through Sunday the 16th, it’s pretty much flat or blown out with tiny leftover slop. You’re looking at a good six or seven day stretch of nothing.

The only break on the cards is Nera Rivermouth. It’s a sheltered river-and-beach setup, which explains why it barely sees any size. This spot wants swell from the SW to really work, but the problem is the swell is tiny and the wind is almost never in the right place to clean it up.

For that Monday morning (17th August), we get a sniff of something with the swell pushing to about 4 ft from the SSW, with a long period of 17 seconds. The combined energy hits 681 (moderate), so there’s some push behind it. But here’s the kicker: it’s cross-shore from the SE at 9 mph, which will put a bit of a chop on the surface. It’s not clean. Still, that long-period groundswell could wrap in a little better shape at the river mouth, but it’s not for beginners, and this spot is inconsistent as it is. Water temp is about 73°F which is pretty normal for this time of year, so no surprises there.

Through the rest of that week and into the next, the size drops back to knee-high or nothing. There’s a brief window on Wednesday the 26th of August, morning and afternoon, where we see 2 ft to 2 ft from the SSW with a 16-17 second period. The combined energy is 175 to 220 (weak to low moderate), and the wind is finally cross-offshore from the ESE at 9 mph, making things clean. It’s surfable but ordinary – little dribblers for the longboard or a foamy. Crowds are possible here, so you might have company for the ankle-biters.

Overall, the best of a bad bunch is that Monday the 17th with the long-period 4 ft swell, if you’re desperate and can deal with the cross-chop. Otherwise, the 26th of August offers clean but tiny waves. The rest is a write-off. It’s one of those stretches where it just doesn’t stay poor for long normally, so forecasts might change, but right now, it’s a long wait.

Stay patient.

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.
