The Lowdown
Alright folks, Rusty here with a look at the upcoming surf. We’ve only got one spot on the menu for this stretch, so let’s get into it.
The pattern starts off a bit slow, but there’s a real window of opportunity building. The first few days are pretty flat and messy, so don’t bother paddling out just yet. Things start to look interesting from Thursday, July 30th, with a clean 3 ft SW groundswell and glassy conditions showing up. That’s our first real chance at a wave, though it’s on the smaller side.
The standout period is really from Tuesday, August 4th, through to Thursday, August 6th. The morning of Tuesday the 4th sees the swell holding at 3 ft from the SW with a gentle offshore breeze, but the real gem is Tuesday afternoon. The wind drops to glassy, the swell is a clean 3 ft from the SW with a 15-second period, and the combined energy nudges up to 606 (moderate). That’s as good as it gets for clean, user-friendly waves.
The morning of Wednesday, August 5th, is also a cracker, with a 4 ft SW groundswell at 17 seconds and a gentle offshore wind. The combined energy is solid at 933 (moderate). This is a proper long-period swell, which will wrap in nicely at a reef setup like Dunes, though at a beach break it might straighten out a bit. The crowd profile here is “sometimes,” so you might have some company, but it’s worth the paddle.
As we head into the second week, things get more powerful but trickier. The morning of Saturday, August 8th, sees a 6 ft SW swell with a fresh offshore wind, but that’s pushing into the “experts only” zone. The energy is very high at 1657 (strong). It’s a promising but less certain call this far out. A few days later, on Monday afternoon the 10th, we get another glassy window with 3 ft SW swell, but the wind swings around. The break itself, Dunes (reef), is consistent and exposed to the SW, which is right where the optimum swell direction sits. Water temperature is sitting at 75°, which is about average for the time of year.
Overall, keep your eyes on Tuesday the 4th and Wednesday the 5th for the best combo of size, clean conditions, and manageable power. After that, it’s a waiting game for the bigger, more challenging swells.
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.
