The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line.
We’ve got a cracking run of surf on the cards, all kicking off this Saturday, August 29th, and stretching well into the second week of September. The dominant energy is a long-period SSW groundswell, and the setup is clean offshore winds for most of it. This is a reef break that’s very consistent, so when the conditions line up, it’s game on.
Saturday morning is the real standout to kick things off. The swell is running 6 ft from the SSW with a juicy 15-second period, stacking up combined swell energy at a solid 1552 (moderate to strong). The wind is a light cross-off from the SSE at just 3 mph, so it’s going to be glassy and clean. This is excellent surf for experienced surfers – a proper session.
The offshore winds hold all through Saturday afternoon, Sunday, and into Monday, keeping things tidy. By Monday afternoon (August 31st), the swell has built to 6 ft from the SSW with an 18-second period, pushing the energy up to 1892. That’s top-tier, clean groundswell.
Now, as we hit Tuesday, September 1st, the swell size pushes up over 7 ft – 7 ft from the SSW with an 18-second period, and energy surging to 2494. This is big, powerful, and very long-period. It’s excellent, but this is only for advanced crew. The wave energy is strong, and with that kind of period, the sets will be hefty and well-spaced.
The quality holds through the first week of September, with clean offshore winds every day. Thursday the 3rd and Friday the 4th see the swell dip a touch to 4 ft, but still with solid 14-15 second periods. Still very surfable.
Into the second week, from about the 7th and 8th, the wind turns a little cross-off, and the quality is a bit more mixed. The size picks back up – 8 ft on Monday the 7th – but the conditions are a touch lumpier. The real standout in this second week is Wednesday, September 9th. We get a clean 6 ft SSW swell at 14 seconds, light offshore winds from the ESE at 12 mph, and combined energy of 2085. That’s another excellent day for experienced surfers.
Then on Saturday, September 12th, the swell really kicks again in the afternoon. We’re looking at a 7 ft SSW groundswell with an 18-second period and a massive 3920 energy reading. This is strong, powerful, and clean offshore, but this is big-water territory for experts only.
The run finishes out on Sunday, September 13th, with 8 ft SW swell at 16 seconds and energy at 2996. The wind is a fresh offshore at 19 mph, keeping it clean, but again – this is real solid stuff.
The best bet, if I had to pick one pure standout, is Saturday morning, August 29th. That first session has the glassy conditions and just the right size. For the more experienced crew, the big pulse on Tuesday, September 1st and Saturday afternoon, September 12th are the ones to circle on the calendar.
This is a reef break, and it’s sometimes busy, so expect a few heads around when it’s this good. Get on it.

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.
