The Lowdown

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

We've got a solid run of surf ahead, starting Tuesday the 15th of September and running through to the end of the month with no real dead gaps. The standout here is Impossibles – a reef break that loves a SW swell and handles the size well. This is a spot for advanced crew only; when it's on, it's on, and it's very consistent.

The forecast kicks off on Tuesday the 15th with a clean 6ft SW groundswell, with a very long 15-second period. The ESE wind is blowing offshore, keeping things glassy. The combined wave energy is strong at 1436, and it's quality surf for experienced surfers. That afternoon holds up at 6ft.

Wednesday the 16th stays clean in the morning with a 6ft SSW swell, still at a 15-second period and 1181 energy. The wind is offshore from the ESE, so it’s looking good. The afternoon gets a bit cross-off, so the morning window is the one to aim for.

Thursday the 17th is a beauty. The morning brings a 7ft SSW groundswell with a 14-second period, and it's clean with offshore ESE winds. The combined energy is a hefty 1947. The afternoon sees a drop in wind, turning cross-off, so get out early.

Friday the 18th is another solid day. Morning has a 5ft SSW swell with offshore SE winds, and the afternoon keeps the offshore flow from the SE with a 5ft swell. Both sessions are looking very good.

The weekend kicks off with Saturday the 19th offering a 4ft SSW swell in the morning with clean conditions, and the afternoon goes fully offshore from the SE with a 4ft SW swell. A nice, clean, smaller weekend.

Now, for the real standout of the first week: Sunday the 20th. The morning has a 7ft SW groundswell with a very long 16-second period, and it’s glassy with offshore SE winds. The combined energy is cranking at 2008. This is the pick of the first week – excellent conditions for the experienced surfer.

The run continues. Monday the 21st has a 7ft SW groundswell in the morning with a 14-second period and offshore winds. Clean and powerful. Tuesday the 22nd drops a little in size to 5ft, still with morning offshore winds.

Wednesday the 23rd brings another strong pulse. Morning sees a 7ft SSW groundswell with a 16-second period and offshore ESE winds, packing 1871 energy. The following week continues with consistent SSW swells, ranging from 6ft to 7ft.

Looking further out, Saturday the 27th of September sees the biggest numbers of the forecast. We're looking at a 10ft SSW swell with a very long 18-second period. The combined energy is massive at 6778 in the morning. This is huge, powerful groundswell. However, the winds are cross-off, and the report flags it as marginal. This is strictly for the experts, and the long period will mean it breaks straight at some spots, but Impossibles being a reef should handle it. Monday the 28th still has a solid 8ft SSW swell in the morning with offshore winds, which is also a heavy session for the experienced.

Through the last days of September, the size backs off a touch but the quality holds, with morning offshore winds on the 29th and 30th. Crowds are listed as "sometimes" at Impossibles, so you might have company on the peak, but the quality of the wave makes it worth it. The water temp is about average for the time of year.

This is a great run. Get on it.

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.
