The Lowdown
Alright, Rusty here. Let’s see what Dunes has in store.
The first few days are pretty quiet, not much to get excited about until Thursday morning, July 28th. That’s when we start seeing some clean lines. Water temp is about 75°F, normal for the season.
That Thursday morning, July 28th, we’ve got a clean 3ft south-west swell with a moderate offshore breeze out of the east-northeast at 19 mph. The combined energy is moderate at 284. It’s a reef break with a 14-second period, so the waves will have some shape and push, though the long period might make them a bit walled at times. Still, it’s a goer.
The big one to lock in is Saturday morning, August 8th. Glassy conditions, dead calm, with a 6ft south-west groundswell. The combined energy is a big 1743, and that’s proper power. The 16-second period means long, grinding lines on the reef. This one is for the experienced crew – the swell size is pushing into expert territory. Saturday afternoon the wind goes onshore, so get it early.
Friday, August 7th, is also a good call. The morning brings a clean 4ft south-west swell with a fresh offshore breeze from the southeast at 16 mph. The combined energy hits 1386, and that 18-second period is generating some serious length and power. Conditions will be clean and the reef should be working.
Dunes can get a few heads out there sometimes, so don’t expect to be alone on those good mornings. If the swell kicks much higher, you might think about kiting instead, but for a good paddle session, aim for August 7th and 8th.
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.
