The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.

We’re looking at a period that’s got a bit of a slow start, but there’s a proper standout session brewing in the middle of the week that’s worth circling on the calendar. The water is sitting at 75°, which is about average for this time of year, so no surprises there.

The first real action we’re talking about is on Wednesday the 9th of September. The morning is the pick of the bunch. We’ve got clean, 4ft groundswell rolling in from the southwest with a solid 16-second period, giving it some real push and shape. The wind is offshore from the east-southeast at 15 mph, which will keep the faces of the waves at Dunes looking immaculate. This is a reef break, so it’s expecting that long-period swell, and with a combined energy of 844 (moderate), it’s got enough grunt to give you a proper ride. This is the standout session for the first week.

Now, the real gem of the whole forecast window is on Saturday the 12th of September. The morning session at Dunes is the one you’ll want to be in the water for. We’re looking at a solid 6ft swell from the west-southwest with a very long 18-second period – that’s proper groundswell, full of energy (1664 combined energy). The wind is light from the south-southwest, giving you a clean, cross-off breeze. The forecast says "excellent surf conditions for experienced surfers", and it’s not wrong. At 6ft, it's a solid size, so it might be a bit much for beginners. For the rest of us, this is the best on offer, without a doubt. Keep in mind, crowds are possible here, so get in early.

The rest of the period is a mixed bag of clean mornings and choppy afternoons, with the wind picking up regularly. There’s a notable pulse of size on the 18th of September (Friday afternoon) with a 6ft swell from the west-southwest and a combined energy of 2381 – that’s strong energy. But the wind is a messy cross-shore at 22 mph, making it a lumpy, bumpy affair. Unless you’re a fan of a wrestling match, that one’s better left for the kites.

The very end of the run, on Monday the 21st of September morning, shows a small but clean 4ft swell with light offshore winds, and the forecast says "expect very good surf conditions". It’s a small window, but a promising one.

So to wrap it up: the best days are the morning of Wednesday the 9th and the absolute standout morning of Saturday the 12th of September. The second week has some size but is mostly wind-affected; the 21st of September morning is a smaller, cleaner capper to the outlook.

Stay stoked.

Rusty.

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.
