The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got coming up.
Look, it’s a bit of a slow burner to kick things off, but once it gets going, there’s some proper quality on the horizon. The standout for a solid stretch is Impossibles (reef). This spot is very consistent and fairly exposed, with the optimum swell coming from the SW. It’s an advanced break, so not for the faint-hearted, especially when it gets big.
Starting this Sunday 26 July and into Monday, there’s swell in the water, but the conditions are marginal. You’re looking at a 6ft to 7ft SE swell with a 9-second period, and while the wind is blowing fresh offshore (ESE 19 mph), the forecast energy is moderate (812-931) and the reports say it’s questionable due to tide. It’s surfable but nothing to get too excited about.
Tuesday 28 July sees a shift to a long-period SSW groundswell, 3ft to 3ft, with a 16-second period. It’s small but clean with a moderate breeze offshore. The energy is moderate (649-690). For such a long period, the waves will be lined up and better shaped, but small.
Wednesday 29 July and Thursday 30 July build a bit more, 4ft to 5ft SSW swell, 14-15 second period, moderate to fresh offshore winds. The energy ticks up into the three-digit moderate range (798-1507) by Thursday afternoon. Clean conditions, but still nothing top-tier.
Now, from Friday 31 July onward, things start cooking. Friday morning: 4ft SSW, 17-second period, moderate offshore, energy 1527. Rated excellent for experienced surfers. That’s the first real standout. The following Saturday 1 August and Sunday 2 August look even better. Swell bumps up to 6ft, still from the SSW, with a 16-18 second period and light offshore (SE 10 mph). Energy jumps to 1741-2087. That’s clean, powerful, long-period groundswell with glassy offshore wind – perfect for this reef setup.
The next week keeps the quality going. Monday 3 August through Friday 7 August brings consistent 5ft to 6ft SSW swell, 13-16 second period, with gentle to moderate offshore winds. Energy stays strong (1108-2125). Excellent to very good conditions for experienced surfers. The standout mornings here look stellar.
Then we hit Saturday 8 August and Sunday 9 August, and it gets big. Really big. Swell hits 8ft to 12ft SSW, 17 seconds, energy in the 3000-6000 range. That’s expert territory – not for beginners at all. Winds blow moderate to fresh offshore, keeping it clean, but the size will be intimidating.
Finally, Monday 10 August brings 7ft SSW groundswell, 20-second period – that’s very long period and strong energy (6556). Perfect for a reef break like this, with moderate offshore wind. Rated excellent for experienced surfers.
So the best bet? Friday 31 July through Sunday 2 August – moderate size, very long period, clean offshore winds, and that SSW direction hitting the spot just right. After that, it’s still good, but the first weekend of August is where it’s at. The second week gets big and demanding.
Right now, the water temp is about average for the time of year.
If you’re not an advanced surfer, the 5ft+ days from early August onwards will be a handful. The 8ft+ stuff later on is strictly experts only.
That’s the rundown. Get ready for a solid run.

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.
