The Lowdown
Hey folks, it’s Rusty. We’ve got a solid run of swell on the cards for Impossibles across the next couple of weeks. This is a classic reef break that’s very consistent, and it’s fairly exposed to the SW swell – the optimum direction. The water temp is sitting at 79.5°, which is bang on average for this time of year, so no crazy thermals to worry about.
The pattern kicks off Thursday morning, but honestly, it’s a bit of a slow start. The swell is around 5.2ft from the SW, but the combined energy (1188) is only moderate, and the forecast is a bit marginal. The wind is fresh offshore from the ESE, keeping things clean, but it’s not firing on all cylinders yet. Thursday afternoon is similar, with a moderate offshore from the SE and 4.6ft SW swell.
Friday picks up the pace. Both morning and afternoon see clean, moderate offshore winds from the SE, with 4.6ft SW swell and a moderate combined energy (742-829). The conditions are looking very good, but it’s not the standout of the run.
Now, Saturday the 5th is where it gets interesting. The morning brings a nice jump: 6.2ft SSW swell with a long 16-second period, and the combined energy hits 1837 – solid moderate energy. The wind is moderate offshore from the SE, so it’s clean. This is excellent surf for experienced surfers. The afternoon sees a slight bump in size to 6.9ft, but the wind goes cross-offshore from the SSE, so it’s still clean, though the forecast is a bit marginal. This is a standout for the first week.
Sunday the 6th keeps the swell pumping with 6.9ft SSW, 17-second period, and a strong combined energy of 2785 in the morning. The wind is cross-off, so it’s clean, but the forecast is marginal. Monday and Tuesday hold similar size (5.6ft to 6.9ft) with cross-off winds and clean conditions, but the energy stays strong (between 1395 and 3364). The period drops a bit on Monday, but Tuesday afternoon sees a very long 18-second period from the SSW – that’s a groundswell that will wrap in nicely, though it might break a bit straight at a beach break, but here at Impossibles it’ll be a treat.
The real standout of the entire forecast is Wednesday the 9th. The morning shows 7.9ft SSW swell, 16-second period, and a strong combined energy of 2859. The wind is a gentle cross-off from the SSE, keeping it clean. This is excellent surf for experienced surfers. Over 8.2ft, it’s expert territory, so this is for the big-dog crew only. The afternoon holds at 7.2ft with similar conditions.
The second week stays active. From Thursday the 10th through to the 16th, we’re looking at consistent 5.9ft to 6.9ft SSW swell, with periods between 14 and 16 seconds. The winds are mostly gentle to moderate cross-off or offshore, keeping it clean. The combined energy is strong, ranging from 1715 to 2527. A few of these sessions, like the mornings of the 12th, 13th, 14th, and 15th, have moderate offshore winds from the ESE or SE, making for excellent conditions. The 16th looks particularly good with 6.9ft SSW and offshore winds.
The final few days, the 17th and 18th, see the swell drop back to 4.6ft-5.6ft, with moderate offshore winds, but the energy drops to moderate levels. Still a good chance of a wave, but not the high point of the run.
Overall, the best bets are Saturday the 5th morning for solid, clean waves, and Wednesday the 9th morning for the biggest, most powerful swell – but only for experts. Crowds are possible at Impossibles, so get in early for the standouts.

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.
