The Lowdown

Alright, grab your board, let’s have a look what’s on the cards for our local stretch at Dunes.

This forecast covers a solid 16-day run, but don’t get too excited too quickly – the first two days are pretty much a write-off. The swell is there, around 4 ft on Friday the 4th from the SW with a long 14 second period, but that wind is howling. A fresh breeze out of the S is just messing things up, creating bumpy, poor conditions. You’d be fighting the chop more than the wave. The combined wave energy is decent at (465), but the quality is shot. We’ll have to wait it out.

Saturday the 5th is a mixed bag. The morning looks promising, with clean conditions thanks to a cross-offshore breeze, and the swell drops back to 3 ft but picks up a very long 16 second period. The energy jumps to (690), but the forecast says it’s marginal. Still, that’s a clean, lined-up groundswell rolling in from the SW. The afternoon gets blowy again, so it’s a morning mission if you’re keen, but I’d say it’s still a bit shaky.

Sunday the 6th is better on paper, with a touch more size in the afternoon hitting 5 ft from the SW, but the wind stays fresh. It’s clean in the morning, but the real window opens up Monday the 7th. That morning has a fresh offshore from the SE bumping up the quality. Swell sits at 4 ft, solid SW groundswell with a 13 second period, and the energy is strong at (932). This is where the week starts to turn.

Tuesday the 8th keeps the trend – clean, offshore winds, 4 ft SW swell, and a long period. The energy drops a bit to (710), but the conditions are right for a good session. Wednesday the 9th and Thursday the 10th get a bit messy with onshore winds in the afternoons, but the mornings offer some clean windows.

Now, here’s where we get a standout. Friday the 11th of September is a beauty. The morning has near glassy conditions with the lightest of breezes out of the ENE. There’s a 3 ft SW swell with a 14 second period, and the energy is solid at (550). The forecast says “expect very good surf conditions” – and with that light wind, it’s going to be clean and fun. The water temperature is about average for this time of year, so no surprises there. This is your best bet in the first week, no question.

The next week is a bit of a mixed forecast, but there’s one clear highlight. Saturday the 13th of September morning has a 5 ft WSW swell with a nice 15 second period and a clean, moderate offshore wind from the SSE. The combined wave energy hits (959), that’s a solid pulse of energy. This could be the pick of the whole run if the wind holds. It’s got power, it’s got shape, and it’s aimed right.

The rest of the second week is a case of picking your windows, but that Saturday the 13th looks like the standout. It’s a reef break, so that long period SW groundswell will wrap in nicely. It’s consistent here, which is a bonus, and you can expect some company as crowds are “sometimes” around, but that’s the price for a good wave.

All in all, we’ve got a slow start, a clean Friday the 11th to get your hopes up, and a potentially cracking Saturday the 13th to finish the run strong. Keep your eyes on the forecasts.

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.
