The Lowdown

Alright guys, Rusty here, and I’ve been looking at the local picture. Gotta be honest – the next 16 days are a real grind, with a lot of flat spells and only a couple of moments that might be worth paddling out for.

The only spot in the game is Nera Rivermouth, a river and beach break that’s sheltered and good for beginners, but it’s inconsistent, so it doesn’t break often. Water temp is about normal for the time of year, nothing special.

We start Monday, August 10th, with a tiny 1ft SSW swell, cross-off wind, and weak energy. Not worth a second look. Tuesday the 11th is glassy but only 0.3ft – forget it. Wednesday the 12th is the same story: glassy, but no waves.

The swell builds a little through the end of the week. By Friday, August 14th, we’ve got 5ft of SSW swell, but the wind is a moderate cross-onshore, making it choppy. The energy is strong (533), but it’s poor surf. Saturday the 15th is similar: 5ft, cross-onshore, messy.

From Sunday the 16th to Monday the 24th, it’s mostly a washout. There’s one bright spot: Tuesday morning, August 18th. We’ve got 3ft of SSW swell with a cross-offshore breeze, making it clean. The energy is moderate (411). The report says “expect good surf conditions” – this is your best bet. Crowds are “sometimes,” so you might have company, but it’s the only clean window in the whole run.

After that, the swell drops to nothing. By Thursday the 20th, it’s down to 1ft, and from the 23rd onward, there’s zero swell. A long stretch of flat days.

The standout: Tuesday morning, August 18th. It’s small, but it’s clean. If you’re keen, that’s your session.

Rusty.

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.
