The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at a solid 16-day window, mostly focused on Dunes, a reef setup that’s consistent and exposed to the SW. The water temp is about average for this time of year, so a regular 3/2mm steamer will do fine.

The first few days are a bit of a mixed bag with decent size but tricky winds. On Sunday the 6th, we’ve got a 6ft SW swell with a 14-second period – that’s a proper groundswell with plenty of energy (1542). But the wind is a fresh 19 mph cross-off, which cleans it up a bit. The combined energy is strong, but the quality is only marginal. Monday the 7th sees a drop to 5ft SW, still 13 seconds, with a lighter cross-off breeze. The numbers are okay, but it’s more of a grinder than a standout.

The real gem starts to show on Tuesday morning the 8th. The swell drops to 4ft, but the period jumps to 16 seconds – very long-period groundswell. The wind goes pure offshore from the SE at 22 mph. The wave energy is moderate (886), but those clean offshore conditions on a reef will make for some beautifully lined-up, hollow waves. This is the best call for the early week. The afternoon stays clean too, with a cross-off.

Wednesday morning the 9th keeps the magic going with 4ft SW swell, 16-second period, and offshore ESE winds at 16 mph. The energy is moderate (834), but the forecast says “expect very good surf conditions.” This is a genuine standout for the first week. The afternoon turns cross-on and choppy, so get it in the morning.

The second week gets interesting. Saturday the 12th morning brings a 4ft WSW swell, but the period has stretched to 18 seconds – very long. With a light cross-off breeze and low energy (1193), this is a classic long-period reef swell that’ll offer clean, powerful waves for experienced surfers. The energy is moderate. This is another top pick.

Then, on Friday the 18th, the swell starts building again. The afternoon shows 8ft WSW with a 16-second period. The combined energy is very strong (2791). The wind is a fresh cross-shore, but the report says the swell might be too big for this break. For experts only, and likely a bit of a beast. Saturday the 19th morning is still 7ft with a 15-second period, strong energy (1821), and a clean offshore wind. Again, big and powerful, but for the experienced crew.

For the beginners, keep an eye on the 3ft to 4ft days in the middle of the second week, but the winds are often cross or onshore, so it won’t be perfect. The two weeks overall have a lot of surf, but the standout windows are clear: Tuesday and Wednesday mornings of the first week, and Saturday morning of the second week. The late period (18th and 19th) is for the big-wave chargers only.

Rusty out.

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.
