The Lowdown
G'day, I'm Rusty. We've got a solid run of surf coming up at Impossibles, so no waiting around. It's a reef break, advanced, very consistent, and fairly exposed to the south-west swell that's been lining up.
Kicking off Friday the 4th of September, the morning's looking tidy with a 5ft south-west swell, a 14-second period, and a clean offshore breeze from the south-east. The wave energy is moderate at 742, but it's a good start to the stretch. Crowds can be a problem here at times, so get in early.
Saturday the 5th of September is where it starts to get serious. The morning brings a 7ft south-south-west swell with a 16-second period, and again, a clean offshore south-easterly. The combined energy jumps right up to 2022, which is strong. That's excellent, powerful stuff for experienced surfers.
Sunday the 6th of September morning pushes it further with a 7ft south-south-west swell and a 17-second period. That's a long-period groundswell, and at this size, it's for experts only. The energy is very strong at 3127, but it's a cross-off wind, so not quite as perfect as the offshore mornings.
The standout period is clearly the middle of the second week. From Monday the 14th of September through to the end of the run, we see a string of mornings with offshore winds and 7ft to 8ft south-west to south-south-west swells. The energy is consistently strong, between 1928 and 2872. That's proper, clean, powerful reef surfing.
If I had to pick the absolute best, I'd say Thursday the 17th of September morning. You've got a 8ft south-south-west swell, a 17-second period, a clear sky, and a clean offshore breeze. The combined energy is 2855. That's a big, grinding swell with perfect conditions for the advanced crew. The water temp is about average for this time of year.
Friday the 18th of September morning is also a ripper: 7ft south-south-west, 15-second period, offshore wind, and a combined energy of 2872. It's going to be a memorable week.
The first few days have some cross-off winds, but the quality is still there. From the 9th of September onwards, it's consistently excellent for experienced surfers, with plenty of power. This is a long, solid run of surf, so get your sessions in.
Rusty.

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