The Lowdown
Alright, Rusty here, giving you the lowdown on what’s cooking at Impossibles.
The water’s sitting at about 78°, which is normal for the season, nothing freaky.
Right off the bat, we’ve got a solid run of surf kicking off. The first good call is for the afternoon of Sunday, the 23rd. We’re looking at a 6-foot SSW groundswell, with a period of 15 seconds. That’s proper energy, plenty of grunt. The wind is offshore from the SE, so it’ll be clean and lined up. This is a reef break, so it’s strictly for the advanced crew. Expect some company out there.
The surf keeps pumping through Monday, the 24th, with 6-foot SSW swell and a 16-second period, wind still offshore.
We keep the pace going into Tuesday, the 25th, with 6-foot SSW swell, same 16-second period. The morning is a bit cloudy, but the afternoon clears up with clean offshore winds.
By Wednesday, the 26th, it eases slightly to 5 feet, and the period drops to 14 seconds, so still good, just a bit less powerful.
Now, for the real standout. The afternoon of Thursday, the 27th is a special one. The swell is a modest 4 feet, but the period is a very long 20 seconds, which means those waves will have serious shape and power. The wind is a gentle cross-offshore breeze, making for clean, glassy conditions. That’s a dream setup for a reef.
Following that, Friday, the 28th, the swell jumps up to 8 feet with a 16-second period – that is big, only for experts. The morning is clean with offshore wind, but it gets a bit messy in the afternoon.
The surf stays solid through the end of August and into the first week of September. On the 1st of September, we get a 6-foot SW swell, 17-second period, and clean offshore winds. The 2nd holds 7-foot SW swell, still with great wind.
We then get a bit of a lull around the 4th, with the swell dropping to 4 feet, marking the end of the most consistent run.
But then, on the 5th of September, another big pulse arrives. The morning brings 6-foot SSW swell, and the afternoon pushes it to 7 feet, both with 16-second periods and strong energy. The wind is offshore all day on Saturday, so that’s a top-tier session.
After that, the swell drops back down through the 6th and 7th, becoming more moderate and less reliable.
The best bet is clear: the afternoon of Thursday, the 27th, for that long-period, clean, glassy gold. The second big moment is the morning of Friday, the 28th for the big-wave crew. Get after it.
Rusty.

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.
