The Lowdown
Alright, surfers, Rusty here. Let’s get straight into it. We’ve got a solid run of south swell lined up for the reef, and it’s looking like a proper stretch of waves for those who know what they’re doing. The water’s sitting at 79.3° which is pretty much spot on for this time of year, so no surprises there.
We’re kicking things off this Wednesday morning. It’s not huge, but there’s a clean 5.6ft SSW groundswell rolling in with a 15-second period. The ESE wind is keeping it glassy and organized. The energy reading is strong at 1451, and it’s a proper reef setup, so expect some serious shape. It’s an advanced wave, and with that kind of quality, you'll want your wits about you.
As we move into Thursday the 6th, the swell is already on the push. Morning sees 6.9ft from the SSW with a longer 17-second period, and the wind is still offshore, though a bit fresher at 30 km/h. The energy jumps to 2460, and it's feeling powerful. The afternoon stays solid at 6.9ft with a 16-second period. This is the start of the good stuff.
Friday the 7th is where it really starts to stand out. We’ve got 8.2ft of SSW swell with a 17-second period in the morning, and the offshore wind is holding. The energy is climbing hard, hitting 3331. This is a strong, powerful groundswell, and the reef is going to be handling it beautifully. The afternoon is just as good, with 8.2ft and a 16-second period, and the energy even pushes up to 3628. This is a standout session for experienced surfers. The conditions are clean, the swell is meaty, and the period is long. This is the one to circle.
Saturday the 8th brings a bit of rain in the morning, but don't let that put you off. The swell is still a solid 7.9ft from the SSW with a 16-second period. The wind is offshore, and the energy is still strong at 2786. It’s still excellent, but the tide might be a bit iffy in the afternoon as it goes cross-offshore. The quality is still there, though.
Sunday the 9th is a bit of a mixed bag. Morning has 6.9ft with a 16-second period and a clean offshore wind, but the afternoon turns cross-off with a lower score. It’s still surfable, just not as perfect.
Now, here’s where we need to talk about the big one. Monday the 10th. The morning is decent at 6.9ft with a massive 19-second period. But it's the afternoon that’s the real story. The swell jumps to 9.8ft from the SSW, and the energy reading absolutely explodes to 7001. This is very strong, powerful surf. The wind is cross-off, but the sheer size and period of this swell will have the reef working overtime. This is for experts only. If you’re not absolutely on your game, this is a day to watch from the shore.
Tuesday the 11th will still be big. The morning is 9.8ft with a 17-second period, and the offshore wind is back, making it clean. The energy is at 5580, so it’s still a beast. The afternoon backs off slightly to 9.8ft with a 16-second period, but it’s still a serious session.
The middle of the week, the 12th, sees the swell ease to a more manageable 7.2ft, with a shorter 15-second period. The winds are still offshore and it’s clean. It’s still a great day, but a step down from the earlier giant.
Then we get a bit of a lull before Thursday the 13th brings another push. Morning has 9.8ft from the SSW, with a 16-second period and an offshore wind. The afternoon is even better, as the wind drops to a gentle 15 km/h offshore, and you get 8.2ft of clean, lined-up swell. This is another standout. The energy is strong at 3668, and the conditions are going to be epic.
The following couple of days, the 14th and 15th, keep the quality high with 8.2ft of swell and consistent offshore winds. It’s not as big as the peaks, but it’s solid, powerful, and clean. The 16th sees the wind pick up to a fresher 30 km/h, which is still offshore, but it will add some texture.
We’ll see a dip in size around the 17th and 18th, with the swell dropping to the 4.9ft to 5.9ft range, but the offshore winds hold, so there will be some fun, smaller waves on offer.
But mark my words, the run from the 19th and 20th of August is looking like another major event. The 19th has 8.2ft of SSW swell with a

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.

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.
