The Lowdown
Alright folks, Rusty here. Let’s break it down.
We’ve got a solid run of surf lining up at Uluwatu, starting this Wednesday, the 12th of August, and it’s looking like a proper stretch of groundswell for the experienced crew. The water temp is sitting at 79°, which is about normal for this time of year, so no surprises there.
The overall pattern is a long, consistent pulse of SSW and SW swell, with offshore winds holding for almost the entire period. The combined wave energy is strong to very strong, with values mostly in the 2000s and 3000s, and even hitting the 4000s by the 22nd. That’s serious energy.
Kicking off Wednesday morning, the 12th, we’ve got 7ft of SSW swell at a very long 17 seconds, with a clean 15 mph offshore breeze. The energy is pumping at 2857, and the waves will be excellent for those who know what they’re doing. This is a reef and point setup, so that long period will wrap in beautifully. Crowds are always a factor here, so be ready for that.
Thursday the 13th is a standout. The swell bumps up to 8ft from the SSW, still holding that 17-second period, and the energy jumps to 3894. Winds are still offshore and clean. This is proper, powerful groundswell – the kind that makes you earn your waves but rewards you with deep, long barrels.
Friday the 14th drops back a touch to 7ft, but it’s still solid. The weekend shapes up nicely too, with Saturday the 15th offering 7ft waves and a lighter 9 mph offshore breeze in the afternoon – that’s going to be glassy perfection.
The first real standout of the whole period is Saturday the 22nd of August. We’re looking at 10ft of SW swell, 16-second period, and energy readings over 4000. That’s big, powerful, and only for experts. Winds are offshore from the SSE at 12 mph. This is a serious day – it’s going to be charging.
The week after that, from the 23rd, the swell backs off a bit but stays fun. The morning of the 25th has 6ft of SSW swell, and then the 26th brings a light 6 mph breeze in the morning – that’s about as clean as it gets. The energy is still there, but the size is more manageable.
Overall, the best on offer is the 22nd of August for the big, powerful stuff, and the 13th of August for that first punch of groundswell. If you’re an advanced surfer, this is your window. Beginners should stay well clear – especially when it’s over 8ft.
Rusty.

Information about the Uluwatu Surf forecast
The above surf forecast table for Uluwatu provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Uluwatu can be found by selecting the local surf guide option on the grey menu. Our Uluwatu 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 (Uluwatu) 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 Uluwatu 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.
Uluwatu is 14 km (9 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.
