The Lowdown

Alright, let's get down to it. The ocean's been a bit messy to start, with a cross-off wind and some rain showers making things feel a bit average. Water temp is at 79°, which is pretty normal for this time of year, so no need for extra rubber.

The first few days, Tuesday through Thursday, look like a write-off for any quality waves. There's swell, but the wind's got that cross-off angle and there’s rain around. Tide's also looking dodgy, so it's a bit of a mush-fest. The energy's there, we're seeing three-digit numbers like 2916, but it's not translating into clean surf.

Then things turn around. From Friday the 11th, the wind goes offshore from the ESE, and the surface cleans right up. Swell is coming from the SSW-SW, and we're starting to see some longer periods. Friday morning has a solid 6ft of SSW swell with a 16-second period, and you can feel the difference in the water. The energy readings are still strong (1930), and the reef at Impossibles (Big Island) will handle it well. It’s a very consistent spot, so there’ll be waves, but it will be busy.

The weekend looks like a good time. Saturday the 12th has a slightly smaller 5ft morning swell, but it's clean and offshore. The period drops a bit to 14 seconds, but it's still got some push. Sunday the 13th sees that SW groundswell building again, with 6ft and an 18-second period in the morning. That's serious long-period groundswell, so the reef's going to be wiring up. It gets better as the day goes on, with the afternoon swell bumping up to 7ft.

The first half of next week keeps that offshore flow. Monday the 14th has 6ft, Tuesday dips a bit to 6ft, but it's still clean. Wednesday the 16th is similar, but the afternoon gets a bit tricky with the tide. It picks back up on Thursday the 17th with 7ft and solid energy.

Now, for the main event. You need to circle the 22nd of September. The swell is back, with 7ft in the morning from the SSW, and the period is at 17 seconds. The energy is cranking at 3785, and the wind is offshore and clean. That's the big one. It's a powerful, well-ordered swell, and the reef at Impossibles is going to be absolutely firing. This one's got your name on it, but it's over the 5ft mark, so it's for the experienced crew only. Too big for the beginners.

After that, the 23rd keeps the size up, with 7ft and similar energy (3606), but the afternoon wind and tide get a bit cross-off, so the morning will be the time to go.

So, the early part of the week is for studying the charts. From Friday onward, it's game on. The long-period swells in the second week are less certain, but that 22nd is looking like the one to plan your life around.

Stay stoked.

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.
