The Lowdown

Alright folks, Rusty here. Let’s break down what’s going on at Nera Rivermouth for the next couple of weeks.

Honestly, it’s a slow start. The first few days are a total washout. Nera Rivermouth is a sheltered river-and-beach setup, and it’s flat or messy for a while. Sunday the 26th through the end of July is basically a no-go. There’s a big pulse of energy on Sunday afternoon with a raw 8ft SSW swell and a massive energy reading (2627), but the wind is cross-shore and the conditions are marginal. Not worth the hassle. The water temp is around 73°, which is pretty average for this time of year.

We get a little breather after that. Monday the 27th and Tuesday the 28th show some size, but the wind is still dirty. Tuesday morning is the first real chance. The swell drops to a clean 5ft from the SSW with a 12-second period, and we get a light cross-offshore breeze. The combined energy is moderate (634), and it’s clean. This is the best window in the first week. It’s a good size for most surfers, and the conditions will be fun.

Then we hit a long, dry spell. From Wednesday the 29th all the way through to Tuesday the 5th of August, it’s tiny, weak, or blown out. Nothing to ride. A few glassy mornings pop up with knee-high slop, but the energy is below 100 (weak) and the swell is just too small. The big, long-period swells (15-20 seconds) are just passing through under a flat ocean.

The next real chance comes on Wednesday the 5th of August morning. The swell picks up to 3ft from the SSW, period is a solid 16 seconds, and the wind is light cross-offshore from the east. The combined energy is moderate (295). It’s small, but clean. If you’re itching to get wet, that’s your spot.

The standout, though, is the end of the run. Look at Monday the 10th of August afternoon. The swell bumps up to 5ft from the SSW, period is 12 seconds, and we get offshore wind from the ENE. That’s a clean, 5ft wave with light breeze and a combined energy of 739 (moderate). The conditions are tagged as “good surf conditions.” That’s the one to save. It’s a river-mouth break, so with that long-period groundswell, it might be a bit straight, but with offshore wind, it should hold up nicely. It’s not huge, but it’s got enough power.

Crowds can be a thing here sometimes, so if you’re heading out on that Monday afternoon, expect a few other folks in the lineup.

Rusty, signing off.

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.
