The Lowdown

Alright, grab your board and listen up. It's Rusty. We’ve got a single spot on the menu for this whole 16-day stretch, and it’s a proper heavy one: Impossibles. This is a reef break, it’s very consistent, and it’s going to be pumping. The water is at 78°, which is about average for the season, so no surprises there.

The action starts on Monday, 24 August. It’s a slow start with a 6-foot swell from the SSW, but it’s a long-period groundswell with a 16-second interval – that’s proper energy (1705 units). The wind is offshore from the SE, so the faces will be clean. It’s a bit of a warm-up. Tuesday the 25th is similar with 6-foot swell, and the afternoon picks up a notch with excellent conditions for the experienced heads. Wednesday the 26th is a little smaller, 5-foot to 5-foot, but still with that clean offshore wind.

Now, the real standout builds on Thursday, 27 August. The swell is 5-foot from the SSW, but the energy jumps to 2790 – that’s a solid pulse. The wind is cross-offshore, so it’s clean but not glassy. Then Friday, 28 August, is the big one. We’re looking at 8-foot of SSW swell, with a 16-second period and a massive 3731 energy reading. That is a serious wall of water. This is expert territory only – over 8-foot on a reef is no joke. The morning session has offshore wind, and it’s prime for the experienced crew. That is your absolute peak. The afternoon on Friday is still pumping at 8-foot, but the wind goes cross-off, so it’s a bit messier.

The weekend of 29-30 August still has plenty of juice. Saturday morning has 6-foot with a gentle offshore breeze, which will be beautiful. 5-foot on Saturday afternoon with a cross-off. Sunday the 30th starts with 5-foot, but the afternoon is weird – a tiny 2-foot swell but with a 21-second period. That’s a very long-period groundswell, which means it’ll be incredibly clean but very inconsistent. It’ll be more about the glide than the punch.

The first week of September is stacked. Monday the 31st has 5-foot to 6-foot with excellent conditions. Tuesday 1 September and Wednesday 2 September have consistent 7-foot to 7-foot swells, all with offshore winds and excellent ratings. That’s a solid run of high-quality surf. Thursday 3 September drops to 6-foot to 6-foot, still very good. By Friday 4 September, it’s easing to 4-foot to 5-foot, and the energy drops below 1000, so the sting is gone.

The second week is a bit of a mixed bag. Saturday 5 September is small, 4-foot to 4-foot, with a bit of cross-off wind. But then Sunday 6 September and Monday 7 September see a new pulse of 7-foot to 7-foot SSW swell, with a 15-second period. That’s excellent, but the wind is cross-offshore, so it’s not as perfectly clean. The energy is still solid (around 1900). Tuesday 8 September finishes the run with 6-foot and a gentle offshore wind in the morning – a nice way to wrap it up.

So, to sum it up: Friday 28 August morning is the undisputed best. 8-foot, 16-second groundswell, offshore wind, and a massive 3731 energy reading. It’s a proper slab for experts only. A close second is the run from Monday 31 August through Wednesday 2 September, with 6-foot to 7-foot swells, solid SW direction, and offshore winds every session. That’s a fantastic stretch of clean, powerful surf. Expect some company out there, especially on the weekends – it’s a popular spot.

Stay safe, and don’t get caught inside.

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.
