The Lowdown
G’day, Rusty here. We’ve got a solid run of swell on the cards for Uluwatu, starting this Friday the 11th and firing right through until the end of the month. It’s one of those forecasts where you just want to clear your schedule – consistent, quality groundswell and clean offshores are the story.
First up, Uluwatu (Bali). The water’s sitting at 79°, which is pretty much bang on average for this time of year, so no surprises there. Friday morning kicks things off with a 6 ft SW groundswell, period a fat 16 seconds, and a light offshore breeze from the ESE at 12 mph. That’s proper clean. The energy is pumping at 1865 – that’s moderate-to-strong. This is a spot for experienced surfers; it’s a reef and point break that gets crowded (almost always), but with that quality, you’ll be in the right place. The swell direction (SW) matches what this wave really wants.
Friday afternoon holds similar 6 ft SSW swell, still 16 seconds, and it stays offshore. Saturday the 12th, it drops a tad to 5 ft SW at 14 seconds, still clean in the morning with 12 mph offshores. Energy drops to 1727, still solid. Sunday the 13th is a standout: morning kicks off with 6 ft SW at 18 seconds (that’s proper long-period groundswell), energy jumps to 2512, and by the afternoon it’s 7 ft SW at 17 seconds with 2635 energy. That’s big, powerful, and clean all day with offshores. That afternoon session on Sunday is the highlight of this first week – serious power, only for experienced surfers. Monday the 14th, the morning is a bit marginal, but the afternoon comes back with 6 ft SW at 16 seconds and clean conditions.
The whole of the next week, from the 15th through the 18th, keeps pumping 6 ft to 6 ft SSW/SW swell, periods between 14 and 16 seconds. Winds stay offshore or cross-offshore, mostly light to moderate. There’s a slight dip on the 19th with 4 ft to 4 ft SSW swell at 14 seconds, energy down around 820-878 – still good for a fun session but not the big stuff.
Then from Sunday the 20th it really winds back up. Morning has 7 ft SW at 16 seconds, 2666 energy, clean with 12 mph offshores. Afternoon is 7 ft SW at 16 seconds, 2444 energy, and a gentle offshore. This is another standout day – that size with that period is proper groundswell and the reefs will love it. Monday the 21st holds 7 ft to 7 ft SSW swell. The energy stays strong. From the 22nd through the 26th, we’re looking at 6 ft to 7 ft swell, mostly SSW/SW, with periods of 13 to 19 seconds. The 19-second pulse on the afternoon of the 25th is very long-period – these are the kind of waves that will wrap beautifully around the point. Energy peaks again on the 26th at 2712 and 2790, with 7 ft to 7 ft SSW at 17 seconds, offshores all day. That Saturday the 26th is a true standout – late in the run but the quality still looks excellent.
Overall, this is a very consistent stretch. Uluwatu is firing. Best sessions: Sunday afternoon the 13th, Sunday the 20th, and Saturday the 26th as a long-range promise. Crowds will be a factor – it’s always packed – but the wave quality is off the charts. Keep it on your radar.
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.
