The Lowdown
Alright, surfers, Rusty here. We’ve got a solid run of swell on the cards for Impossibles, so let’s break down the next couple of weeks.
The window kicks off with a bit of a teaser on Thursday afternoon the 27th. There’s swell in the water at 5ft from the SSW, but the conditions are a bit touch-and-go with a cross-offshore breeze. It’s surfable, but it’s not the day to call in sick for. The energy is moderate (2315), but we’re waiting for things to clean up.
And clean up they do. Friday the 28th is where it starts to get proper. Overnight, the swell bumps up to 8ft from the SSW with a long 16-second period, and the morning breeze swings offshore. This is a powerful, clean groundswell, the kind that gets the heart pumping. The energy is strong (3499). This is a day for experienced surfers only, given the size. It’s a standout, no doubt.
Saturday the 29th sees the swell easing slightly to 6ft, still from the SSW, with a light cross-offshore wind. It remains clean and very good, a great follow-up day. The energy is still healthy (1534). Sunday the 30th drops a bit more, with 5ft on the morning, but the wind is properly offshore. It’s still a lot of fun and cleaner for it.
Monday the 31st brings a new pulse of long-period energy. The swell is a touch smaller in the morning at 4ft, but the period has stretched back out to 18 seconds. This is a proper long-period groundswell, and by the afternoon it's pushing 6ft. The energy is building (1361 to 1889). With offshore winds, this is another excellent window, especially for a reef like Impossibles which will handle that long-period energy well.
Tuesday the 1st of September delivers the goods. We’ve got 7ft of SW swell with a 17 to 18-second period and strong offshore winds all day. This is the peak of the run. The energy is strong (2634). It’s big, it’s powerful, and it’s clean. This is the other true standout of the forecast, a day for the confident crew.
The rest of the first week into the second week sees a gradual drop in size, from 7ft down to 4ft by the 4th and 5th, but the wind stays offshore for most of it. The quality remains high, just with less power behind it.
There’s a bit of a lull on the 9th and the morning of the 10th, with some smaller 3ft to 4ft surf, but then things pick up again. The 11th of September sees another push of SW swell, back up to 6ft with a 16-second period and solid offshore winds. It’s a promising end to the fortnight, but being that far out, I’d say it’s a promising prospect rather than a sure thing. The water temp is sitting at 79°, which is about average for this time of year, so a boardshorts and a rashie is all you’ll need.
The calls are Friday the 28th and Tuesday the 1st. Both are big, powerful, and clean. 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.
Impossibles is 12 km (7 miles) from the city of Kuta. If you plan a holiday in The Bukit - Bali, look for hotels and other accommodation in Kuta. Kuta has rooms for a wide range of budgets as well as car hire and transport links.
