The Lowdown
Alright folks, Rusty here. We’ve got a solid run of swell on the way, so let’s get into it.
The standout is Impossibles, a heavy, advanced reef break. It’s very consistent and fairly exposed to the swell, with an optimum direction from the SW. The water is sitting at 79°, which is pretty much bang on average for this time of year.
The action kicks off Friday the 7th of August. We’re looking at a clean 8ft SSW groundswell with a long 17-second period, and a moderate offshore breeze from the ESE. This is excellent for experienced surfers, but at this size and with that period, the reef will be cranking – this is not for the faint of heart. The combined energy is strong at 3333. Saturday morning the 8th holds more of the same, with 8ft SSW swell and 16-second period, still clean with offshore winds, though the energy is still very strong at 2999. Saturday afternoon the wind goes cross-offshore, but it’s still a solid 8ft.
Sunday the 9th sees the swell ease slightly to 7ft, but with clean offshore winds and a 16-second period, it’ll still be pumping. The real highlight in the first week might be Monday the 10th morning. The swell drops to 6ft, but the period stretches to a very long 19 seconds, and we get a gentle offshore breeze. The combined energy absolutely roars to 4023, and the quality is rated top-notch. This is a dream session for a point or reef like this – long, powerful lines with easy paddling between sets.
Tuesday the 11th afternoon looks fantastic again, with the swell bumping back to 8ft and a solid offshore breeze cleaning it up. The energy is a massive 4700. Wednesday the 12th keeps the quality going with 8ft and offshore winds.
Now, looking further ahead, the 13th of August (Thursday) we see a jump in size to 12ft, but the wind goes cross-offshore, so while it’s clean, it’s not as perfect. The 20th of August (Thursday) is a big one to circle on the calendar. The swell is back up to 12ft SSW, with a 18-second period, and the wind is a light breeze, swinging offshore in the morning. The energy is a staggering 6663. This is a long-range call, so keep an eye on it, but if it hits, it’ll be an all-time day for the experts.
However, keep in mind that this is a reef break, so those long-period swells (over 15 seconds) will be dismantling themselves into perfect, heavy corners. The crowds are noted as ‘sometimes’, so you might have some company, but it’s not a circus.
The second week (from the 14th onwards) holds plenty of clean, solid surf, with the 7ft to 8ft range mixing in with a few bigger pulses. The 18th of August (Tuesday) afternoon sees a spike to 8ft with a 17-second period and offshore winds, energy hitting 5240, another very promising window.
The only real gaps are if you’re looking for small, gutless waves. There’s none. The swell is consistent and the winds are mostly offshore or cross-offshore. For the average surfer, anything over 8ft is going to be a handful, especially on a reef. If you’re not an advanced surfer, the 5ft to 6ft days on the 15th of August and the 17th of August will be your best bet, though the 17th has a fresh breeze.
This is a top-tier run for Impossibles. 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.
