The Lowdown
Alright folks, let’s talk what’s in the water. This is Dunes, a reef break that handles a south-west swell best. Water temp is about 75°, which is a touch warmer than the average for this time of year – nothing major.
Tuesday, August 25th – forget it. 1.1m swell from the southwest, but the wind is cross-on and messy. Stay on the beach.
Wednesday, August 26th morning – this is a gem. The wind is dead calm, glassy as a mirror. Swell is just 1.0m from the southwest, but it’s got a 14-second period. Combined energy is weak at (459), but it’s a beautiful, clean little wave for a longboard. Perfect. The afternoon gets ruined by a westerly wind.
Thursday, August 27th morning is the king of this forecast. You get a solid 1.9m southwest groundswell with a 17-second period. The wind is clean offshore from the SSE. Combined energy is a strong (2062). This is a proper, powerful, clean wave for experienced surfers only. This is the session to get excited about. The afternoon drops off and gets cross-shore.
Friday, August 28th morning – tricky. Still a decent 1.6m of swell, but that offshore wind is blowing a stiff 40 km/h. The waves are clean but you’ll be fighting to paddle in. The afternoon is smaller and cleaner but nothing special.
The weekend is small. Sunday, August 30th morning gives you another glass-off. Tiny 0.9m swell, but with an 18-second period and (550) energy. It’s a gentle, long-period wave – perfect for a lazy cruise.
Monday, August 31st through Wednesday, September 2nd gives you 1.3m to 1.4m of southwest swell. The standout here is Tuesday, September 1st morning: 1.4m, 16-second period, clean cross-off wind, combined energy at (1025). A good, solid session.
Thursday, September 3rd and Friday, September 4th are blown-out and drop to 1.0m. The wind is too strong.
Then a dead spell from Saturday, September 5th to Monday, September 7th morning. The swell is tiny at 1.1m, but the wind is howling at 35-40 km/h. It’s more a kite-surfing wind than a wave you want to paddle.
Monday, September 7th afternoon is a straight-up onshore mess.
A late pulse hits Tuesday, September 8th morning: 1.7m southwest swell, 19-second period! The combined energy is strong at (2055). Wind is cross-off. It’s a big, long-period swell that will wrap in, but that period is so long it might get tricky. This one’s for the experienced crew.
Wednesday, September 9th morning rounds it out: 1.4m, 16 seconds, clean. A nice last chance.
The best day without question is Thursday, August 27th morning – big, offshore, and clean. For the glassy, small-wave lover, Wednesday, August 26th morning is the dream. The last week is mostly full of strong winds and small swell, with that Tuesday September 8th pulse being the only wild card, but it’s a long way out so don’t bank on it.

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.
