The Lowdown
G'day, Rusty here. We’ve got a solid run of surf coming up at Impossibles, a reef setup that’s an advanced-only kind of wave. It’s a very consistent break, so you can count on it.
The water temp is sitting at 80°F, which is pretty much normal for this time of year.
The action kicks off on Thursday, 30th July. The morning sees a 5ft SSW swell with a 15-second period, and it’s clean with a moderate offshore breeze from the ESE. The combined energy is strong at 1261. The wind shifts a bit in the afternoon, with a fresh offshore from the SE at 19 mph, keeping things clean. The swell holds at 5ft, and the energy bumps up to 1535.
Friday, 31st July, is a step up. The swell is 4ft, but the period lengthens to 17 seconds, and the wind is a moderate offshore from the SE at 12 mph. The energy is still strong at 1495 in the morning and 1477 in the afternoon. The conditions are excellent for experienced surfers. The same pattern holds for Saturday, 1st August, with a 5ft SW swell in the morning and a 6ft SSW swell in the afternoon, with a 18-second period. The wind is gentle offshore, and the energy jumps to 2291 in the afternoon. The water anomaly is about average.
The standout period is from Sunday, 2nd August, through Tuesday, 11th August. The swell builds and holds, with the best on offer being Sunday afternoon, 2nd August, through to Monday, 10th August. The best single session is Tuesday, 11th August, afternoon: a 10ft SSW swell with an 18-second period, combined energy of 4920, and a gentle offshore breeze. That’s big, powerful, and clean. It’s only for experts, though—over 8ft, so don’t even think about it if you’re not solid.
The run of clean offshore winds holds through the first week, but from Friday, 7th August, the wind turns cross-offshore, and the swell stays in the 7ft to 8ft range. The 8ft days on 6th, 9th, and 10th August are also big and powerful, but the wind is a bit stronger.
The second week gets a bit more mixed. The wind shifts around, with some cross-off and cross-shore conditions. The swell remains strong, with the energy staying in the 2000-4000 range. The 10ft swell on 11th August afternoon is the biggest, but the wind is clean. The last few days, from 12th to 14th August, have lighter winds but the swell starts to drop, with a 4ft, 20-second period on 13th August afternoon. That’s a long period, so it’s better at this reef than a beach break.
Overall, this is a great run for experienced surfers. The first week is the pick, with the best clean conditions and solid swell. The biggest, cleanest day is Tuesday, 11th August afternoon. Don’t be a hero if you’re not ready for it.
Rusty.

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.
