The Lowdown
Right then, let’s have a look at the next sixteen days.
We’ve got one spot on the menu, and it’s a proper heavy-hitter: Impossibles. This is an advanced reef break, very consistent, and it’s going to be absolutely pumping for a solid run. The water temp is sitting at 79°, which is about normal for this time of year, so no surprises there.
The action kicks off on Monday afternoon, the 10th of August. We’re looking at a solid 10ft SSW groundswell, with a long 18-second period. That’s a lot of water moving, and the combined energy is massive at 5492 (strong to very strong wave energy). The wind is a cross-offshore from the SE at 12 mph, keeping things clean. This is big, powerful, and for experienced surfers only. It’s a bit of a beast out of the gate.
Tuesday morning, the 11th, is when things get really special. Same 10ft SSW swell, still a 17-second period, but the wind swings fully offshore from the SE at 12 mph. That’s the standout session. Glassy, clean, and powerful—this is the best on offer. The energy is still huge at 5261. The crowds are listed as ‘sometimes’, so expect a few, but for waves this good, it’s worth it.
The size drops a little through the rest of the week, but it stays consistently in the 7ft to 8ft range, with that long-period SSW groundswell and offshore winds holding for most of the mornings. Wednesday the 12th through to Saturday the 15th all have good morning windows with clean conditions and moderate offshore breezes. The energy stays in the moderate to strong range (2857 to 2929). It’s going to be a fantastic run of surf.
Into the second week, the pattern holds. Sunday the 16th and Monday the 17th see the swell dip a touch, with 5ft to 7ft, but still with offshore winds. The energy on Monday the 17th drops to 1018, which is moderate, but still perfectly surfable.
Then it ramps back up. Tuesday the 18th and Wednesday the 19th bring back 7ft to 7ft SSW swell with good periods and strong offshore winds. Thursday the 20th sees a slight shift to a SW direction, with 8ft swell and a fresh 19 mph offshore wind in the afternoon—still clean, but getting windy.
The real cherry on top comes on Sunday the 23rd of August. The swell drops to 4ft, but look at the period: 21 seconds. That’s a very long-period groundswell, and it’s coming from the SSW. The wind is light offshore from the SE at 6 mph. For a reef like Impossibles, that’s magic. The combined energy is 2477, which is moderate, but the quality of the wave will be exceptional. This is a sneaky standout for the more patient surfer.
And then, to finish the run, Monday the 24th of August thumps back in with a 10ft SSW swell, 17-second period, and gentle offshore winds. The energy is back up to 4449. A big, powerful finish.
So, the standout is Tuesday morning, the 11th of August, for the peak size and glassy offshore conditions. The dark horse is Sunday the 23rd for that incredibly long-period, clean, smaller-scale perfection. This is a long, consistent run of high-quality, powerful surf. It’s all for experts, but it’s a proper dream spell.
Stay safe out there.

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.
