The Lowdown
Alright, Rusty here. Let’s talk surf for the next couple weeks.
That early stretch kicks off Sunday the 30th of August with clean conditions. A steady offshore breeze out of the ESE is holding everything together, and the swell is running 4 to 5 feet from the SSW with a solid 13-second interval. The combined energy is moderate (839 to 924), so there’s enough push but it’s not crazy. Good size for an intermediate surfer with the wind in your face.
The real highlight starts Monday the 31st of August. Monday morning the swell holds at around 4 feet, but the period jumps to 18 seconds – that’s real groundswell, long lines, big gaps between sets. Combined energy jumps to 1367, and by afternoon it’s 5.5 feet with 1892 energy. The offshore wind stays locked in at 25 km/h, so the surface will be glassy. This is the best of the first week, hands down.
Tuesday the 1st of September keeps the quality. Morning sees 6.2 feet of SW swell at 18 seconds, combined energy at 2320. Strong, powerful, and clean. This is expert territory. Afternoon nudges up to 6.5 feet with a 17-second period, still excellent.
Wednesday the 2nd and Thursday the 3rd hold the offshore breeze and keep the swell in the 5 to 6-foot range with 16-second period. Thursday afternoon the wind switches to cross-offshore, so the cleanest morning windows are gone after that.
Friday the 4th gets a bit smaller, about 4.5 feet, but the wind is back offshore, so you’ll have clean, fun waves all day.
Saturday the 5th sees the swell bump back up to 5.5 to 6 feet, but the wind goes cross-offshore, so the surf won’t be as clean. Still surfable but not the pick.
Sunday the 6th of September is a big one. Morning has 4.5 feet of swell at 18 seconds with combined energy at 2400 – powerful – but the wind is cross-offshore and conditions are only marginal. Afternoon pumps to 7.5 feet with 3160 combined energy, still cross-offshore. That’s big and only for experts.
Monday the 7th stays in that 6.5 to 7-foot range with cross-offshore wind.
Now, the second major standout: Wednesday the 9th of September. Swell hits 8 feet from the SSW with a 17-second period and combined energy at 3296. The wind is back offshore from the SE at 20 km/h. That’s the biggest, cleanest, and most powerful day in the whole forecast. Experts only.
Thursday the 10th morning has a gentler offshore breeze with 6.5 feet at 15 seconds, still very good.
From Friday the 11th through Monday the 14th of September, the pattern settles into a steady 5-foot swell from the SSW to SW at 14 to 15 seconds with consistent offshore or gentle offshore winds. Combined energy stays between 975 and 1171. Clean, rideable, and fun for intermediate surfers. The longer period means these waves will be better on the point break than a beach break.
Water temp is typical for this time of year – nothing unusual.
One thing to know: Impossibles can get busy, so if you want the best clean sets with that long-period groundswell, get in early. The sets will be spaced out, so be patient and pick the good ones.

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.
