The Lowdown

Alright folks, Rusty here, and I’ve been staring at this one for a while. Honestly, it’s a bit of a slow burn, and the first few days are a write-off. But if you’re patient, there’s a couple of windows that could be worth paddling out for.

The only spot on the cards is Nera Rivermouth. It’s a sheltered river and beach setup, and it’s inconsistent—when it gets a swell, it can be fun, but it’s not a bank you can rely on every day. The water temp is about average for this time of year, so nothing crazy there.

We start off with nothing. No surf to speak of right away. Monday the 31st of August is a total dud: tiny 1ft to 2ft swells with a cross wind and really poor conditions. The energy is weak (50 to 123). Tuesday the 1st of September is even worse in the morning—flat, zero energy. The afternoon sees a 6ft SSW swell jumping in with a very long 16-second period, and the energy is strong (1678), but the wind is a fresh cross breeze and the report says poor surf. It’s a frustrating tease.

That brings us to Wednesday the 2nd of September. This is the first real standout. Wednesday morning is looking clean. We’ve got a 6ft SSW swell, long period of 15 seconds, and a light cross-offshore breeze. The energy is strong (1459) and the conditions are described as clean. This is it, the best of the early window. The swell is a bit much for a beginner, but for anyone with some experience, it’s on. The 5ft to 6ft range is good, solid size. The only catch is that Nera Rivermouth is a river mouth, and a long-period swell can sometimes run a bit too straight, but with the light offshore wind, it’s worth a look.

The rest of the week is patchy. Thursday the 3rd has a marginal 5ft swell with a cross-on wind, just okay. Friday the 4th and Saturday the 5th are small and mostly poor. Energy drops right back to double digits.

Now, look ahead to Sunday the 6th of September. This is another standout. Sunday morning is glassy. Absolutely glassy. We’ve got a 5ft SSW swell with a very long 17-second period, and the energy is strong (1099). The wind is a slight air, practically flat calm. The conditions are described as glassy. This is a morning for the log or a mid-length, just clean, peeling lines. The period is long, so it’ll be a bit more powerful and have good shape, but it’s not too big. It’s a good one.

Then we get a lull again. Monday the 7th and Tuesday the 8th morning, though, Tuesday morning the 8th of September has a serious spike: 7ft SSW swell, 16-second period, and a light cross-offshore wind. The energy is huge (2329). This is expert territory. The report says excellent conditions for experienced surfers. If you’re good and you’ve got the right board, that’s a session. But the afternoon goes marginal with a cross wind, so get in early.

The rest of the run into the second week is mixed. Wednesday the 9th morning has a clean 5ft swell, nice but not the highlight. Thursday the 10th is tiny. Friday the 11th and Saturday the 12th have some size—10ft on Saturday morning with a strong 11-second period, energy of 2095—but with a cross-offshore wind, it’s still marginal. That’s big, punchy, and only for the brave. The 10ft is a proper beast, and with a short period, it’s going to be a bit of a washing machine. Not a beginner spot that day.

Sunday the 13th and Monday the 14th drop back to small, marginal, or flat. The last sniff of any real swell is on Tuesday the 15th of September, with a tiny 0.5ft pulse, but it’s not worth getting wet for.

So, to wrap it up: The two sessions to pencil in are Wednesday the 2nd of September morning and Sunday the 6th of September morning. Tuesday the 8th morning is for experts only. The rest of the 16 days is mostly a lot of waiting, with a few glimpses of something decent. Stay patient.

Rusty.

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.
