The Lowdown

Alright folks, Rusty here. Let's have a look at what Nera Rivermouth has in store for us over the next couple of weeks.

The outlook starts with a bit of a slow burn, nothing special, but there’s a sweet little window brewing. We’ve got a couple of good days coming up, but you’ll have to be patient. The overall pattern is one of small pulses.

Thursday the 16th kicks things off, but it’s nothing to write home about. We’ve got 3ft of SSW swell rolling in, but it’s very ordinary. The energy’s moderate (368), but it’s not the kind of thing that’ll get you out of bed early.

Friday the 17th is a bit cleaner with a light offshore breeze from the ENE. Swell drops a little to 2ft from the SW, energy easing back to 218. It’s clean, but still pretty small.

Now, Saturday the 18th is where it starts to wake up. The swell pushes up to 3ft to 3ft from the SSW, and the period jumps right up to 17 seconds. That’s proper groundswell energy, and with 523-624 of combined energy in the water, it’s got some push. The wind is light offshore from the ENE, so it’s going to be clean. This is a decent shout.

Sunday the 19th is the real standout of this entire forecast period. We’re talking glassy conditions, a light NE wind, and the swell hanging in at 3ft from the SSW. But the period? It hits 21 seconds. That’s a very long period groundswell. The energy reads a solid 588-982, which is strong. The water temp is about average for this time of year. This is the day to point the car at Nera Rivermouth. Be warned though, that long period swell can make a river mouth setup a bit wonky, but when it’s glassy like that, it’s worth the roll of the dice. The break can be inconsistent, so keep an eye on it.

Monday the 20th sees a cross-on breeze from the SSE creep in, and the quality drops to marginal. The swell’s still around 3ft, but the wind is gonna mess with it. Worth skipping.

After that, we hit a real rough patch. From Tuesday the 21st right through to the end of the month, it’s mostly poor conditions. Strong cross-onshore winds, lumpy chop, and very low energy. The swell drops off a cliff, and we even see a couple of days with no measurable swell at all. This is a long gap of about a week and a half with very little to offer.

There’s a tiny glimmer on the morning of Saturday July 26th – glassy conditions with a 1ft SSW groundswell at 16 seconds (155 energy). It’s surfable, but tiny.

The next proper opportunity doesn’t come until Thursday the 30th of July. The morning looks glassy again, with 3ft of SSW swell at 14 seconds and moderate energy (479). Conditions are clean, and the rating is good. This could be a nice little session for the experienced crew who don't mind punting for a clean but small wave.

So, to put it simply: your best bets are Saturday, July 18th and Sunday, July 19th. Sunday is the absolute standout for the whole 16-day run.

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.
