The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got one spot on the radar for the next couple of weeks, and it’s a doozy for the experienced crew. The overall pattern is a long, drawn-out pulse of solid SSW groundswell, but with a catch – the wind is a bit of a tease for the first few days, keeping things from being truly perfect.
The first real opportunity kicks off on Sunday, September 6th. Impossibles is seeing a building swell from the SSW, pushing 7 ft with a very long period of 17 seconds. The water is a warm 79°, which is pretty much bang on average for this time of year. The energy is strong (2958), but the wind is a cross-off from the SE at 12 mph. It’s clean, but that cross-off angle means it’s not the absolute peak shape. This holds through Monday and Tuesday, with the swell staying solid in the 6 ft to 7 ft range, periods still long, but that cross-off breeze keeps the scores moderate.
Now, the real standouts start to appear from Friday, September 11th. The wind finally swings offshore from the ESE at 12 mph, and the swell is still a grunty 7 ft from the SSW with a 16-second period. The energy is strong (2022), and the conditions are described as moderate offshore and clean. This is the moment. Impossibles is a very consistent reef break, and it’s advanced only, so this is not for the faint of heart. The crowd factor is "sometimes", so you might have some company, but with this quality, it’s worth it.
This excellent stretch of offshore winds and solid swell continues right through the following week. The best of the best looks like Saturday, September 12th and Sunday, September 13th. Saturday morning has a clean 5 ft SSW swell with offshore ESE wind, and Sunday brings a bigger 7 ft SW swell with the same clean offshore wind. The energy is strong (2288) on Sunday. The waves will be powerful, lined up, and clean. This is the pick of the fortnight.
Further out, a new pulse of energy arrives around Saturday, September 19th and Sunday, September 20th. The swell bumps up to 8 ft to 10 ft from the SSW, with strong energy (3880-3887). This is a very powerful swell, definitely for experts only. The wind on the 20th is offshore again, making for a potentially epic, but heavy, session. Just be aware that with a period of 16 seconds and a big swell, the sets will be big and the lulls between them long.
The last few days of the window, the 21st, still have solid 7 ft swell and offshore winds, but the energy is dropping off. It’s still good, but the real fireworks are the 11th through the 13th, and that big spike on the 20th.
Rusty, signing off.

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.
