The Lowdown
Alright, this is Rusty comin' at ya from the lineup.
Right off the bat, the next 16 days are all about one spot and one spot only: Impossibles. It’s a heavy, advanced reef break that’s very consistent and handles a SW swell perfectly. The water is sittin' at a warm 80°, which is pretty much bang on average for this time of year, so no surprises there. The overall pattern is a long run of clean, rideable surf, but don’t get too excited just yet—the early part of the week is a bit of a tease.
Wednesday the 2nd starts things off with a clean, moderate offshore wind from the ESE, but the swell is a bit grumpy at 6ft with a long 16-second period. The energy is moderate (1970), but the wave comment says the surf is marginal, so it’s a bit of a flat-feeling session despite the size. Thursday the 3rd drops a little to 5ft, still clean and offshore, but the energy dips (1069) and it’s still not firing on all cylinders. Thursday afternoon gets a bit better with 5ft and 15-second period, but we’re still in the warm-up zone.
Friday the 4th stays in that 5ft range with a slightly shorter 14-second period. The morning is clean and the afternoon picks up energy (1110), but the score is still just "very good" conditions, not a standout.
Now, here’s where it gets interesting. Saturday the 5th is the first real standout. The morning brings a solid 7ft SSW groundswell with a 16-second period, the wind is a gentle 9 mph cross-offshore, and the energy jumps to 2024 (moderate-strong). The wave comment calls it "excellent surf conditions for experienced surfers." This is a big, powerful, long-period swell hitting a reef, so it’s for the crew with the right equipment and the right nerves. Crowds are possible here—it’s a spot that gets busy, and on a Saturday with a clean 7ft wave, expect company.
Sunday the 6th keeps the energy high (2766) with 7ft SSW swell and 17-second period in the morning, but the wind is a bit more side-on from the SSE. It’s clean, but the wave comment says marginal, so the tide or the shape might be a bit off.
The whole second week is a long run of clean, cross-offshore winds, with swells bouncing between 5ft and 8ft. The energy stays strong, often in the 1600–3700 range, with periods from 14 to 19 seconds. This is groundswell territory. Tuesday the 8th afternoon is a beast – 7ft SSW, 18-second period, energy at 3700 (strong). Wednesday the 9th morning hits 8ft with 16-second period and 3164 energy. These are expert-only waves. The wind is cross-off, not perfect offshore, but still clean enough. The wave comments are consistently "marginal" for these bigger days, which means the setup might be a bit tricky for the average surfer.
Saturday the 12th is a weird day. Swell drops to 3ft but the period hits 21 seconds. That’s a very long-period, low-height groundswell. Energy is still decent (1786) but that long period on a reef will likely produce clean, walled-up lines—but also long lulls between sets. Good for a paddle-out but not a pumping session.
Sunday the 13th is another true standout. Morning brings 7ft SW with a 17-second period, 2683 energy, and the wind swings back to a moderate offshore from the ESE. That’s the best wind of the whole run for Impossibles. The wave comment says "excellent surf conditions for experienced surfers." If you can only pick one day this week, this is the one.
The final days, from the 14th to the 17th, settle into a consistent 5ft to 6ft SW swell with offshore winds in the mornings and clean afternoons. It’s a solid end to the run—good, clean, powerful waves for the advanced crew, but nothing quite as epic as that Saturday the 5th or Sunday the 13th.
In short: The first week is building to a peak on Saturday the 5th. The second week has one true standout on Sunday the 13th. Everything in between is good, clean, heavy reef surf for experienced surfers only. Beginners, stay well clear—this wave is no joke.
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.
