The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a full 16-day window ahead, but I’m not gonna lie to you – it’s a tough stretch for Nera Rivermouth. The overall pattern is pretty flat and messy, with a real lack of quality. There’s a big gap of nothing happening from the start, so we’ll have to wait a while for anything even worth a mention.

The first bit of surfable swell shows up on Wednesday morning, August 5th. We’re looking at small 3ft groundswell from the SSW, with a long 16 second period. The water temp is sitting at 73°, which is pretty normal for this time of year. The energy is weak (291), and the wind is cross-off from the ESE. It’s clean, but it’s small and the conditions are very ordinary. Not one to get excited about.

The next few days are a write-off. Thursday the 6th has a tiny 2ft swell and then drops to nothing. Friday the 7th through to Wednesday the 13th is a long, flat run with barely a ripple – waves are mostly 0.3ft to 0.7ft. The wind is off or glassy at times, but with no swell to push, it’s just a blank stretch. That’s a solid week of nothing.

Then things get a little more interesting, but not in a good way. On Thursday the 13th of August, the swell picks up to 3ft from the SW, but it’s onshore and choppy with wind hitting 15-18 mph. The energy is moderate (229), but the quality is poor. Friday the 14th sees a bigger jump – 5ft from the SW, with a short 9 second period. That’s a lot of lumpy, cross-shore chop (461 energy). This is more of a kite-surfing setup than a paddle-surfing one, especially with those fresh winds.

Saturday the 15th of August is the biggest swell on offer, with 6ft from the SSW. The energy is strong (771), but it’s still cross-shore and bumpy. For a beginner spot like this, 6ft is a bit much, and the wind keeps it from being clean. Not your day.

Sunday the 16th has a drop back to 2ft, but the energy is still moderate (389) with a long 15 second period. The wind is still cross-shore, so it’s not great. We get a glimmer on Monday the 17th with 3ft from the SSW, a long 17 second period, and very light cross-shore wind. The energy is moderate (556), and it’s the only day that gets a marginal score. It’s not a standout, just the least bad option.

The rest of the window fades out again. Tuesday the 18th has a small 3ft, and Wednesday the 19th drops to 0.7ft. Thursday the 20th has glassy conditions in the morning, but with a tiny 0.7ft swell, it’s flat.

There’s no real standout here. The best on offer is that Monday the 17th of August, with the 3ft SSW groundswell and light winds, making it the cleanest of a pretty average bunch. But honestly, don’t plan your week around it. The break is inconsistent at the best of times, and this run looks typical for the area. Keep an eye on the forecast, because it tends not to stay this poor for long.

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.
