The Lowdown
G’day, Rusty here, and I’ve got a bloody good look at what’s ahead for Impossibles. This is a reef setup, and it’s a proper advanced wave – no messing around. The water temp is sitting at 79.3°F which is pretty much normal for this time of year, so no dramas there.
We’ve got a solid run of swell coming in. The first recommendation kicks off Thursday morning, August 6th, with a 6.9ft SSW swell, a very long 17-second period, and a clean offshore wind from the ESE at 18.6 mph. The combined energy is strong at 2581. It’s a bit marginal for tide, but the wind is making it look clean. That trend holds through Thursday afternoon, with a similar 6.9ft swell and 16-second period, still clean.
Friday, August 7th, is where it starts to get exciting. Morning brings a 8.2ft SSW swell, 17-second period, and offshore ESE wind at 15.5 mph. The combined energy jumps to 3345, and the conditions are marked as excellent for experienced surfers. That’s a standout window. Friday afternoon is more of the same – 8.2ft, 16-second period, and clean offshore wind.
Saturday, August 8th, has a morning shower but the wind is still offshore at 15.5 mph, with a 7.9ft SSW swell. The energy is 2786. It’s still excellent for experienced surfers, but the rain might put a bit of a dampener on it. The afternoon clears up, with 7.5ft and clean wind.
Sunday, August 9th, the swell drops slightly to 6.9ft, but the wind stays offshore in the morning. It’s a bit more marginal for tide, but still rideable. The energy is 2228.
Now, Monday, August 10th, is a ripper. The swell hits 6.6ft in the morning, but with a very long 19-second period coming from the SSW. The combined energy is a massive 4315. The wind is a cross-off from the SSE at 9.3 mph, clean. The afternoon is even bigger – 9.8ft, 18-second period, and 5749 energy. That’s a lot of water moving. This is a standout for the week, but at 9.8ft, it’s expert-only territory. The long period means it’ll be breaking deep and fast on the reef.
Tuesday, August 11th, is another cracker. Morning has 9.8ft, 17-second period, and 5128 energy, with a cross-off breeze. The afternoon drops to 8.2ft but stays offshore and clean. Both sessions are marked excellent for experienced surfers.
Wednesday, August 12th, cools off a bit, with 7.5ft and 6.9ft, but still offshore wind and clean. The energy is still strong.
Thursday, August 13th, is a monster. Morning shows 11.5ft, 17-second period, and 6596 energy – the biggest of the whole run. That’s a serious swell, only for the hardcore. Offshore wind keeps it clean. The afternoon is 9.8ft with 5835 energy.
The second week starts to settle. Friday, August 14th, has 8.2ft, and the morning is offshore, but the afternoon goes cross-off. Energy is still around 3454. Saturday, August 15th, is a winner – morning has 8.2ft, 17-second period, and a gentle offshore breeze at 9.3 mph. The energy is 5325. That’s a standout for the second week – clean, solid, and less wind.
Sunday, August 16th, the wind picks up to 18.6 mph, still offshore, but the swell is 7.5ft and 7.2ft. It’s a bit more lumpy. Monday, August 17th, the swell drops to 5.6ft and 5.2ft, energy down to around 1200 – small and weaker.
Tuesday, August 18th, picks up again to 6.6ft and 7.9ft, with fresh offshore wind. Wednesday, August 19th, has 8.2ft, and the morning is offshore, excellent for experts. Thursday, August 20th, is a beauty – morning has 8.2ft, 17-second period, and a light offshore breeze at 6.2 mph, with energy at 4123. The afternoon is similar with a gentle offshore. That’s a clean, solid morning.
Friday, August 21st, the wind is up again at 18.6 mph, but still offshore, with 8.2ft swell. The energy is 3870.
The true standouts in this run are Monday, August 10th, with that 9.8ft, 19-second groundswell and massive energy, and Thursday, August 13th, with the 11.5ft peak. Both are for experts only, but the wind is clean and the swell is pumping. Saturday, August 15th, is also a ripper for the second week, with gentle offshore and solid energy.

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.
