The Lowdown
Alright, Rusty here. Let’s talk about what Ketewel has in store for ya.
Straight up, it’s gonna be a tough stretch. The swell is pumping consistently, often over 5ft, and sometimes pushing 8ft or more, so there’s plenty of water moving. But the wind is our enemy here – stuck out of the southeast, blowing cross-onshore, messing up the surface for most of the period. The water is 80°, just a touch warmer than normal for this time of year.
It starts on Monday, August 10th. Monday morning shows a 6ft SSW swell with a 15 km/h cross-on wind (3381 combined energy). It’s not clean. Monday afternoon jumps to a thumping 10ft SSW swell (4753 energy) – that’s expert-only territory, and with onshore wind, it’s a bumpy beast.
Tuesday the 11th stays heavy. Both sessions have 10ft SSW swells with a 16-second period. That long period groundswell can bring good shape on a reef, but the onshore wind will chop it up.
From Wednesday the 12th through Saturday the 15th, we’re looking at 7ft to 8ft swells, all from the SSW or S, with cross-on SE winds around 15 km/h. The combined energy sits in the 2000s–3000s (strong to very strong), but the quality isn’t there.
Your best chance at something decent comes early on Sunday, August 16th. The morning sees a 7ft SSW swell (2075 energy) with a light breeze of just 10 km/h, still cross-on but very light. It’ll only have small wind ripples – not glassy, but it’s the cleanest window in the whole outlook. That’s your session if you can only pick one.
After that, it drops off. Monday the 17th sees the swell fall to 5ft and the conditions go poor. There’s a real dry spell from the 18th to the 22nd, with several days of zero-rated conditions and poor surf. Nothing doing.
Then on Sunday, August 23rd, a new pulse shows up: 8ft SSW swell with a 18-second period (4484 energy), but the same old SE cross-on wind returns. Monday the 24th has a 8ft SSW swell (3009 energy) with a lighter 10 km/h SSE wind that’s more onshore – could offer some long, heavy lines but still not pristine.
So the standout is that Sunday the 16th with the lightest breeze. Everything else is a fight against the wind. The consistency is there, but the quality is missing. Ketewel (Bali) can handle the size, but you’ll be battling a bumpy surface most days. Watch for crowds – it can get busy.
Rusty.

Information about the Ketewel Surf forecast
The above surf forecast table for Ketewel provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ketewel can be found by selecting the local surf guide option on the grey menu. Our Ketewel 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 (Ketewel) 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 Ketewel 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.
Ketewel is 7 km (4 miles) from Denpasar. If you plan a holiday in Sanur - Bali, look for hotels and other accommodation in Denpasar. Denpasar has rooms for a wide range of budgets as well as car hire and transport links.
