The Lowdown
Alright folks, Rusty here. Let's get into it.
We've got a solid run of swell coming in, but it's not for the faint of heart. The main event is all about Impossibles, a heavy reef break that demands respect. The persistent offshore wind out of the ESE and SE keeps things clean, but the size and power of the swell will keep the crowds of groms and beginners away, which is a bonus for the crew who know what they're doing.
The forecast kicks off on Wednesday, July 29th, with a clean but unremarkable 4ft to 4ft SSW swell. The energy is solid (811 on the dial), but the wave comment calls it marginal, so it's a bit of a warm-up. Thursday, July 30th, sees the swell building to 5ft and the energy ramping up.
Friday, August 1st, is where things start to get interesting. The groundswell from the SSW pushes 5ft with a 16-second period, and the energy is strong (1689). The wind is a gentle offshore breeze, making it glassy. The wave comment calls it excellent for experienced surfers. This is a standout for the week.
The real muscle shows up on Sunday, August 10th, and pushes through the next week. We're looking at solid 8ft SSW swell with 16-second intervals. The energy is strong (3175) and the wind is blowing clean offshore. This is a proper, powerful groundswell that will make Impossibles tall and testing. It's only for the experts at this size, but it will be world-class.
The biggest spike of the whole run is on Friday, August 7th, when the swell hits 10ft out of the SSW. The energy is massive (8069). That's serious, big-wave territory. Only the most experienced chargers should be looking at this. The wind is a moderate offshore, so it will be a clean, gnarly beast.
For the best of the best, I'd be circling Sunday, August 2nd, and Saturday, August 8th. The 2nd has a clean 7ft swell with a moderate offshore breeze, and the 8th drops slightly to 8ft after the big peak, still with a clean offshore wind. The water temp is a balmy 80°F, which is dead average for this time of year, so you won't need a thick wetsuit.

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.
