The Lowdown

Alright, grab your wettie, let’s look at what’s coming up for the next couple of weeks. The only spot on the radar that’s even worth talking about is Dunes. This is a reef setup, and it’s consistent, which is a good start. The water temperature is about average for this time of year, nothing too wild, just normal.

Right now, there’s nothing happening. The first real chance to get wet won’t come until Tuesday afternoon, the 4th of August. That afternoon, we’ve got a modest 3ft swell from the southwest, with a long 15-second period. The wind is light and cross-offshore, which will keep things clean. The combined wave energy is moderate (522). It’s not pumping, but it’s a window to get out there.

Now, the standout window is Wednesday the 5th through Friday the 7th. Wednesday morning is the one to circle. We’re looking at 5ft of southwest swell, with a 17-second period – that’s proper groundswell energy. The wind is offshore from the SSE, so expect clean, lined-up waves. The combined energy is strong (1050). This is a session for experienced surfers, but it’s the best on offer. The reef handles this long-period swell well, so it won’t just close out. Expect crowds to be possible here, as it’s a consistent spot.

Thursday morning the 6th is nearly as good, with 5ft swell and a 16-second period, light cross-offshore winds, and strong energy (1271). Again, clean and punchy. Friday morning the 7th drops off a touch, but still has 5ft swell and clean conditions.

The second week is a bit of a letdown. There’s a gap from around the 11th to the 13th where the swell drops to 3ft and the wind is howling offshore, making it hard to paddle into. The standout in this quieter period is Thursday afternoon the 13th. The swell is still only 3ft, but the wind goes glassy, and the period is 15 seconds. Combined energy is low (308), but with glassy conditions and a long-period groundswell, the reef will produce some fun, clean little waves. It’s a sneaky good session if you’re patient.

Then on Friday the 14th, the swell bumps back up to 4ft, with a 15-second period. The afternoon goes glassy again, and the energy is moderate (521). That’s another solid call for a clean, cruisy session.

The very end of the window, Monday the 17th, sees a jump in size to 6ft, but it’s from the WSW, and the wind is cross-offshore. The energy is very strong (1650), but with that size and a long period, it’s going to be a handful. It’s promising, but it’s far out and uncertain.

So, to sum it up: if you’ve got one day to surf, make it Wednesday morning the 5th of August. That’s the pick. The Thursday morning after that is near as good. The second week is quieter, but the glassy afternoons on the 13th and 14th are worth a look.

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.
