The Lowdown

Alright crew, Rusty here, giving you the lowdown on the surf for the next couple of weeks. We’re only really looking at one spot: Dunes. It’s a reef that loves a clean SW swell, and it just needs a break from the bad wind to fire. It’s a bit quiet to start, but there’s some juice coming.

The first proper chance to get wet is Tuesday morning, August 25th. Wind is a clean offshore out of the southeast, glassing up the faces. We got a 4ft SW groundswell rolling in with a 13-second period. Water temp is a balmy 76°, just a touch warmer than usual. The combined energy is moderate (414). It’s not huge, but it’ll be clean and fun for a session.

The real standout, the one you tell your mates about, is Thursday morning, August 27th. This is the best of the window. The swell jumps to 6ft from the SW, with a gorgeous 17-second period – that’s proper groundswell. The combined energy is strong (2086). There’s a lot of water moving. And the wind will be a moderate offshore from the SSE, leaving the faces smooth and lined up. This is excellent, powerful surf, but at 6ft, it’s for experienced surfers only. The long period means more time between sets, but when they come, they’ll be set up perfectly for the reef.

After that, the waves settle down a bit but stay clean. Monday morning, August 31st has a nice 5ft SW swell with a 16-second period, light offshore winds, and strong energy (1084). It’s another excellent call for those who know how to handle it.

Then at the top of September, Tuesday morning, September 1st is another excellent option. You got a clean 5ft WSW swell, 16-second period, moderate offshore wind from the SE, and strong energy (1204). Big and clean again.

Things go downhill after the first few days of September. The second week has some mornings with clean but weaker energy, and the afternoons get messy with onshore wind. The weekend of the 5th and 6th has some marginal surf with fresh offshore winds, but nothing to get too excited about. By Monday the 7th and Tuesday the 8th, the wind is blowing onshore and the whole thing turns lumpy and choppy – a good day to stay on land.

So, the plan is simple: aim for the offshore mornings. Thursday the 27th of August is your absolute best shot for the biggest, cleanest groundswell. The Tuesday mornings on the 25th and 1st of September are also solid for clean, powerful waves.

Keep your wax on.

Information about the Dunes Surf forecast

The above surf forecast table for Dunes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dunes can be found by selecting the local surf guide option on the grey menu. Our Dunes 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 (Dunes) 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 Dunes 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.
