The Lowdown

Right then, let’s have a look at what’s coming our way. The big news is that we’ve got a solid run of surf from Thursday the 10th of September all the way through to Friday the 25th of September. That’s a solid sixteen-day window with no dead spells, so you can plan your sessions around the best conditions.

The standout for the whole period has to be the reef at Impossibles. It’s a very consistent, advanced-level break that’s fairly exposed to the swell, and it’s set to pump for days. The water temperature is sitting at 79°, which is pretty much bang on average for this time of year, so no drama there.

We kick off on Thursday the 10th with a clean 7 ft SSW swell rolling in, but the wind is cross-offshore from the SE at 12 mph, and the conditions are described as marginal due to tide. The combined energy is already a strong 2368 (moderate to strong wave energy). It’s surfable, but not the pick of the week.

From Friday the 11th, things tighten up. The wind swings offshore from the SE at 12 mph, and the swell holds at 6 ft to 5 ft from the SW, with a very long period of 16 seconds. That’s proper groundswell energy, and for a reef like Impossibles, that’s pure magic. The combined energy is still solid (1865 to 1727), and the surf is described as excellent for experienced surfers. This is the best run of the first week.

Saturday the 12th and Sunday the 13th are both excellent. Sunday morning sees a 6 ft SW swell with an 18-second period and a combined energy of 2512 – that’s a serious pulse of energy. The wind stays offshore, and the faces will be clean and lined up. If you’re an advanced surfer, this is the session you circle.

The following week, from Monday the 14th to Friday the 18th, keeps the quality high. The swell remains in the 6 ft to 6 ft range, mostly from the SW, with offshore winds holding. The period drops slightly but stays in the 14 to 16-second range, which is still excellent. The combined energy dips a little but stays well into the three-digit range (1436 to 1646). The mornings are particularly good with gentle offshore breezes.

Saturday the 19th and Sunday the 20th see a slight drop in size to 5 ft to 6 ft, but the wind remains favourable and the surf is still very good. The energy drops to 969 on Saturday morning, which is moderate, but it’s still clean and fun.

The last push of the forecast, from Monday the 21st to Friday the 25th, finishes with a bang. The swell picks up again, with 7 ft to 8 ft SSW swells, and the combined energy spikes back up to 2718 on Wednesday the 23rd. That’s strong wave energy. The wind is offshore or cross-offshore, and the conditions are excellent for experienced surfers. Be aware that with swell over 7 ft, this is expert territory – not for beginners.

The absolute best on offer? Sunday the 13th morning with that 6 ft SW swell, 18-second period, and offshore wind. The energy is 2512, and the water is glassy. That’s the one. The second standout is Wednesday the 23rd morning with a 7 ft SSW swell, 16-second period, and moderate offshore wind – pure power for the experienced crew.

Because the crowds at Impossibles are listed as “sometimes”, you can expect company, but with a break this consistent and this good, it’s worth sharing a few waves.

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.
