The Lowdown
Alright, my fellow wave hunters, Rusty here, breaking down the next couple of weeks for Dunes. It's a tale of two forecasts: a slow start, but a late-summer pulse is on the horizon.
The first session worth paddling out for is Monday morning, the 20th. We get a clean 4ft SW swell with a light offshore breeze from the SSE. The water is a comfortable 76°, which is dead average for this time of year. The energy is solid (588), and it's all clean lines. Get it while you can, because Monday afternoon the wind turns cross-shore and it gets messy.
Tuesday the 21st has a fresh offshore, but the swell is smaller at 3ft and the wind is up to 18 mph, making it a battle. Tuesday afternoon cleans up a bit, but the waves are only 3ft.
From Wednesday the 22nd all the way through the end of July, it's a quiet spell. The swell drops off to under 2ft, and even with a few glassy afternoons, there's just no energy to push a decent wave. The numbers are all in the low hundreds, confirming it's a flat spell that lasts over a week.
Now, hold onto your board, because the first of August brings the goods. The standout is Saturday morning, August 1st. We get a solid 6ft WSW swell with a massive energy reading of 1130 (strong wave energy). The wind is a light cross-off breeze, keeping the surface smooth. This is a long-period groundswell (14 seconds), so it'll have power and a nice rhythm. But at 6ft, it's a bit of a handful, so it's best for the more experienced surfers. Then Sunday morning, August 2nd, is almost as good: a 4ft SW swell with a clean offshore breeze. The energy is still strong (565), and the wind is nearly glassy. That's a stunning morning.
For the absolute pick of the forecast, set your alarm for Saturday morning, August 1st. That 6ft WSW groundswell with clean conditions is the one we've been waiting for.
Stay stoked.

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.
