The Lowdown
G'day, I'm Rusty, and I've got the goods on the surf ahead for the next couple of weeks. There's plenty of action on the cards, but it's a run that's geared right up for the experienced crew.
Alright, let's kick things off. The standout spot, and really the only game in town, is Uluwatu. This is a reef and point setup that's super exposed to the SW swell, and that's exactly where the energy's coming from for the whole run. The water temp is about average for this time of year. We've got a nice long run of waves starting Friday morning, 21st of August. The first session kicks off with a clean 5 ft. SSW swell, a long period of 18 seconds, and 12 mph offshore ESE winds. The combined energy is moderate at (2588). It's a clean, solid start for experienced surfers, and the crowds are always a factor here, so get in early.
The energy builds through Friday afternoon and into Saturday morning, 22nd August, with the swell pushing up to 8 ft. and 7 ft., still with offshore winds. Saturday afternoon looks fantastic with a clean 7 ft. SSW swell and 12 mph offshore SE winds. Sunday, 23rd August, drops a touch to 6 ft., but the wind is still offshore and clean, making for excellent morning and afternoon sessions. This pattern of clean, offshore winds and solid SSW swell holds through Monday, 24th August, and Tuesday, 25th August, with the swell sitting around 6 ft. to 6 ft. There's a bit of a lull mid-week, but the quality remains high.
Now, for the real standout. Look at Friday, 4th September. That morning, we're looking at a 8 ft. SSW swell with a super long period of 20 seconds, light offshore winds, and a combined energy of (6169) – that's strong to very strong. The afternoon is even bigger, with 10 ft. SSW swell, 19-second period, and gentle offshore winds, energy at (6569). This is expert territory, no doubt. The waves are going to be significant, deep, and powerful. The long period, long period, means it'll be pulling a heap of water, so the channels and reefs at Uluwatu will be handling it best. The following Saturday, 5th September, still has 8 ft. SSW swell on offer, but it's a notch down from the peak.
There's also a smaller but clean pulse on the 27th and 28th of August, with a 4 ft. to 8 ft. range, but that 8 ft. on the 28th morning is a bit of a bump with cross-off winds. The very end of the run, into early September, sees a consistent stream of 7 ft. to 7 ft. SW swell with offshore winds, keeping the quality high.
Overall, the best bet is that Friday, 4th of September. It's a big, powerful, clean groundswell that'll have the experts frothing. The whole run is for experienced surfers only, so if you're not confident in 6 ft.+ reef waves, give it a miss. The conditions are so consistent that it's a rare treat, but the crowds at Uluwatu will be a given.
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.
