The Lowdown

Alright folks, this is Rusty. Let's have a look at what's coming down the pipe at Impossibles.

We’ve got a solid run of groundswell lining up. This is an advanced, very consistent reef break that really needs a good SW direction, and that's exactly what we’re getting. The water temp here is sitting at 78.4°, and with a temperature anomaly of -0.7°, that’s pretty much right where it should be for this time of year.

Kicking off on Friday, August 14th, we’re looking at a bit of a warm-up with 7.2ft of SSW swell. It’s clean, but the wind is cross-off, and the combined energy is moderate at 2322. It’s a decent start but a little messy. Saturday the 15th is where it really starts to cook. The wind goes offshore from the ESE at 12 mph, cleaning up that 7.2ft to 7.9ft SSW swell. The energy jumps to 2895 and 3202, and the period stretches out to a very long 17 seconds. This is proper groundswell—long lines, plenty of push. It’s an excellent call for experienced surfers.

Sunday the 16th keeps that quality rolling with offshore winds all day, 6.6ft to 7.2ft SSW swell and a 15 to 16-second period. Energy stays strong. By Monday the 17th, the swell drops a bit to 4.6ft to 4.9ft, but it’s still clean. The real meat of this swell train hits from Tuesday the 18th on. That 5.6ft to 6.2ft SSW swell builds, with offshore ESE winds holding steady.

The standout? Mark your calendars for Wednesday, August 19th. We are looking at a pumping 8.2ft to 9.8ft SSW swell with a 17 to 18-second period. That means very long groundswell. The energy is off the charts at 4057 and 4874 – that’s strong to very strong. The wind is blowing offshore at 12 to 16 mph. This is big, powerful, expert-only territory. At over 8ft, this is for the well-prepared crew only. The long period will see it breaking beautifully down the reef, but it’ll be fat and straight at a beach break. This is a point and reef setup, so it’s going to be epic.

Thursday the 20th holds onto that 9.8ft, then drops to 8.2ft in the afternoon, still with clean offshore winds. We then settle into a solid two-week run. From the 21st right through to the morning of the 29th of August, we’ve got consistent 4.3ft to 7.5ft SSW swell, almost always with offshore ESE winds. The energy stays in the low to high thousands – moderate to strong. The only hiccups are on the 27th and 28th of August afternoons where the wind swings a bit cross-off, and on the 29th afternoon it gets a bit messy again. But mostly, it’s a dream run for the advanced surfer.

On Wednesday, August 26th, we get a smaller morning of 4.3ft, but the afternoon pulses back up to 4.9ft with a very long 18-second period. Saturday the 29th sees that same long period swell with 4.3ft to 6.6ft, and gentle offshore winds in the morning. This break can get busy, and given how consistent it’s looking, expect crowds during this whole window.

This is a rare run of quality. Get on it.

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.
