The Lowdown
Alright, this is Rusty. Let’s be straight with you – the next couple of weeks are looking pretty grim for any decent surf. We’ve got a long stretch of nothing good to start, and it’s not until the 24th of August that things finally look like they might turn around.
We’re looking at a solid gap of over a week with no worthwhile recommendations. The wind is a nightmare – a constant fresh cross-shore breeze that’s going to leave everything lumpy and chopped out. The swell is all over the place, but it’s just not lining up with clean conditions. There’s some serious energy in the water on the 16th of August, with a combined energy of 6550, but it’s a 16ft E swell with an onshore wind. That’s a mess, not a session. On the 15th, we’ve got 12ft ENE swell with a 28-31 mph near gale. That’s not for paddling; that’s for kite surfers if anything.
The only real light at the end of the tunnel is for ADs/Doubles on Monday the 24th of August. The forecast is showing a glassy, clean morning with a light 3 mph east wind, shifting to a glassy afternoon with a light wind from the north-west. The swell is 3ft from the SSW with a long period of 13 seconds – that’s proper groundswell. The combined energy is moderate at 541. This is the standout. It’s a small window, but with those conditions, it could be fun on a longboard or a fish. The 25th of August also looks promising with a glassy afternoon and a 2ft SSW swell, but the morning has a bit of an onshore wind. The water temp is about average for this time of year.
So, it’s a long wait. The first week is a write-off. Keep your eyes on that Monday the 24th and Tuesday the 25th. That’s our best shot.
Rusty.

Information about the ADs/Doubles Surf forecast
The above surf forecast table for ADs/Doubles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at ADs/Doubles can be found by selecting the local surf guide option on the grey menu. Our ADs/Doubles 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 (ADs/Doubles) 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 ADs/Doubles 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.
