The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a real mixed bag coming up over the next couple of weeks. The first few days are the only real window of opportunity, with a solid pulse of SW swell and clean conditions. After that, it’s a long, quiet stretch before a much bigger, but wind-affected, swell moves in during the first week of August.
The standout here is Dunes, a reliable reef break on the exposed SW coast. The water is sitting at a comfortable 76°, which is pretty much normal for this time of year, so no worries there.
The action kicks off on Sunday morning, July 19th. There’s a good 6ft of WSW swell rolling in with a 15-second period. That’s a long-period groundswell, which means proper, powerful waves. With a 9 mph cross-offshore breeze from the east, it’s going to be clean. The combined swell energy is strong at 1210, so expect plenty of push. This is the best of the first week. Monday morning, July 20th, is also worth a look. The swell is a bit smaller at 4ft from the SW, still a solid 14-second period, and the wind is a light cross-offshore from the SSE. The energy is moderate at 534, making for a decent, clean morning session.
After Tuesday, the swell drops off fast. By Wednesday, July 22nd, we’re down to 2ft, and the wind is glassy in the afternoon, but the waves are just too small to get excited about. This quiet spell drags on all the way through to the end of July. For over a week, the surf is tiny, and the winds are often onshore or too strong. It’s a real lull.
Things start to look more promising again on Monday, July 28th. A new SW swell arrives, pushing 4ft with a 14-second period. The morning wind is a clean offshore from the SE at 12 mph, and the combined energy is a solid 459. It’s a decent wave, but it’s not the standout.
Now, hold on to your boards. The last few days of the forecast window show a massive increase in swell. By Sunday, August 2nd, we’re looking at 7ft from the SW with a 17-second period. The energy is a massive 2688. But there’s a catch. The wind is howling out of the northeast at 25 mph, straight cross-shore, which will chop it right up. This is expert territory only, and honestly, the strong cross-shore wind makes it look more like a kite-surfing day than a clean paddle session. The Dunes reef will be getting hammered, but the quality will be poor.
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.
