The Lowdown

Alright folks, Rusty here. Let's get into it.

We’ve got an extended run of clean, solid swell on the way. The main action is all at one spot, and it’s a proper reef setup that demands respect. This is not a beginner’s game.

The water temperature is sitting at 80°F with a very small anomaly of 0.4°F, so it’s basically bang on average for this time of year. Comfortable for a long session.

We kick off on Friday, July 31st, with a clean 4ft SSW groundswell rolling in with a 17-second period. That’s a long-period groundswell, meaning proper energy and long lulls between sets. The wind is offshore from the ESE at 16 mph, keeping things glassy. The combined energy is strong at 1493. This is excellent, but it’s for experienced surfers only.

Saturday the 1st steps it up a notch. The morning sees 5ft from the SW at 16 seconds, but the afternoon is where it gets juicy: 6ft from the SSW with an 18-second period. The wind drops to a gentle 9 mph offshore, and the energy jumps to 2437. That’s a standout session – clean, lined up, and powerful.

Sunday the 2nd holds solid at 7ft from the SSW, with a 17-second period in the morning. Energy is 2266. Wind stays offshore all day. This is heavy, consistent reef surf.

Monday the 3rd and Tuesday the 4th keep the quality high with 6ft and 5ft swell, still offshore winds. By Tuesday afternoon, the wind turns cross-offshore, which cleans things up but adds a bit of texture. Still a solid 6ft.

Wednesday the 5th brings back clean offshore winds and 6ft swell. The energy is moderate at 1429. Good, solid surf.

Thursday the 6th is a big one. The morning swell hits 8ft from the SSW with a 17-second period and a fresh 19 mph offshore wind. The energy is 2987 – that’s strong. This is big, powerful reef surfing. The afternoon stays clean with 8ft and 16 mph offshore.

Friday the 7th pushes to 8ft in the morning. That’s getting into expert-only territory. The period is 17 seconds, energy is 3269. The wind is offshore but a bit stronger.

Saturday the 8th holds at 8ft, still with offshore winds in the morning. Energy is 2751. Solid.

Sunday the 9th sees 8ft in the morning with a 17-second period and offshore wind. The energy jumps to 3348. This is a heavy, consistent day.

Monday the 10th is a beauty. 8ft from the SSW, 15-second period, and a gentle 9 mph offshore wind. The energy is 2800. The wind is light, the surf is big. This is a standout.

Now, into the second week, things get serious. Tuesday the 11th of August brings a 10ft SSW swell with a 17-second period. The combined energy is 5076 – that’s very strong. Morning wind is a gentle offshore. This is for experts only.

Wednesday the 12th drops slightly to 8ft, but the wind goes cross-offshore, so it’s clean but not as perfect.

Thursday the 13th is the big one. The morning is 10ft, but the afternoon cranks up to 12ft from the SSW with an 18-second period. The energy is a massive 7805. That’s exceptional, extreme surf. The wind is light. This is the peak of the run.

Friday the 14th holds at 10ft with a 17-second period and energy of 6517. The wind goes light cross-shore, so it’s clean but not glassy.

Saturday the 15th winds down with 8ft and 8ft, still with light cross-shore winds. The energy is still strong.

The real standouts in this entire run are Saturday the 1st of August afternoon and Monday the 10th of August morning. The 1st has that perfect 6ft, 18-second groundswell with gentle offshore wind, and the 10th has the combination of 8ft swell with a super light offshore breeze. Both are prime.

This is Impossibles, and it lives up to its name. It’s a very consistent, advanced reef break. The swell direction is SSW, which matches the optimum SW direction from the guidance. It’s fairly exposed and it’s going to be working hard. Expect crowds sometimes, as it’s a well-known wave.

The entire 16-day window is filled with surf, so no gaps to worry about. Just a long, solid run of clean, powerful swell.

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.
