The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
The overall pattern is a slow burner. We've got a steady run of southwest swell, but for the first week it's small and needs the right tide and wind to line up. The real payoff looks like it's building towards the end of the second week.
We start off Tuesday the 28th with a clean 3 ft SW groundswell, period 13 seconds, and the combined energy is moderate (253). The wind is a cross-off from the ENE, so it's rideable, but the score is a marginal one. Wednesday the 29th is similar – 3 ft SW, 14 seconds, but the wind is a bit stronger. Not terrible, but nothing to get excited about.
Thursday the 30th is where it starts to get interesting. The morning session at Dunes is looking like a standout. The wind is offshore from the ESE, 12 mph, and the swell is still 3 ft from the SW, but the period has jumped to 17 seconds. That's a long-period groundswell, which means proper, powerful lines. The combined energy is moderate (427). The offshore wind will keep it clean. This is the pick of the first week.
Friday the 31st morning is another good window with a 3 ft SW swell at 16 seconds and a gentle cross-off breeze. Clean again. The weekend rolls in with a bump in size to 4 ft SW on Saturday the 1st, but the tide conditions are a bit questionable according to the numbers. Still, the morning is clean with a cross-off breeze.
The next few days, Sunday the 2nd through to Tuesday the 5th, are a bit of a mixed bag with onshore winds and poor conditions, so we'll skip those. The wind and rain are not your friends.
Now, the real highlight. Look at Friday the 7th of August. The morning session at Dunes is a beauty. The swell is 6 ft from the SW, with a very long period of 20 seconds. The combined energy is strong (2169). The wind is offshore from the SSE at 12 mph. This is proper, powerful groundswell. At 6 ft, it's getting into the zone that's more for the experienced crew, and with that period, it's going to be a heavy, well-defined swell. The reef setup at Dunes will love this. The water temperature is about average for the time of year, so no surprises there.
The Saturday the 8th and Sunday the 9th hold onto similar size, with 6 ft SW, but the winds are a bit stronger, though still offshore or cross-off. The energy is still up there. It's a solid run of swell, but the Friday morning is the true standout.
The following week, from Monday the 10th, the swell starts to drop back to 5 ft and then 4 ft, and the winds turn more onshore and cross-off again. The last entry on Wednesday the 12th shows a drop back to 3 ft with a clean cross-off, but it's a return to the smaller stuff.
So, to sum it up: the best surf on offer is Thursday the 30th of July morning for a clean, long-period swell, and the absolute standout is Friday the 7th of August morning for the bigger, more powerful groundswell. That's the one to circle on the calendar. Crowds are a possibility at Dunes, so get out early for the pick of the waves.
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.
