The Lowdown
Alright, this is Rusty. Let’s talk in feet and miles per hour.
Look, I’m not gonna sugarcoat it. The next 16 days at Ketewel are a real mixed bag and honestly, for a spot that’s already a bit of a tease with its inconsistency, this is a frustrating run. The set-up is a sheltered reef that loves a solid south swell, and we’ve got plenty of that coming through, but the wind is the story here. It’s almost always a cross-onshore breeze from the SE or ESE, which is going to keep things choppy and lumpy. It’s not proper offshore, so the wave faces won't be that classic Ketewel wall.
The water is sitting at 80°, which is pretty normal for this time of year, so no surprises there.
We kick off on Saturday, August 9, with a solid 7ft SSW groundswell at a long 16 seconds, but the wind is already cross-on. The combined energy is a massive 2521 (moderate to strong), but that’s tied to a "marginal" call. It’s not clean. Sunday morning and afternoon, August 10, drop to 7ft but the wind stays cross-on. This pattern of "good size, bad wind" just keeps going. The swell is pumping, period is long, and the energy is three-digit and four-digit (like 4753 on Monday afternoon, August 11, with a 10ft SSW swell), but it’s all locked in with that dirty cross-onshore breeze.
The two best moments in this whole window are slim pickings, but here goes. The absolute standout is the afternoon of Monday, August 11. We’ve got a 10ft SSW swell at 18 seconds, and the wind goes "on" (which for this sheltered spot means it’s coming from the SE, straight into the bay). The combined energy is a very strong 4753. It’s big, it’s powerful, and it’s a long-period groundswell. That’s expert territory and the reef will be handling it, but the crowd is a factor since it’s "sometimes" busy. The other one to watch is Friday morning, August 15. A 8ft SSW swell with a 16-second period, and the wind is "on" (SE, 9 mph). The energy is 2640. It’s still a big wave for a reef, but it’s the cleanest window we get.
Don’t get too excited about the second week. By Monday, August 18, the swell drops to 5ft and the wind is still cross-on. The forecast is straight-up "poor surf conditions" then. The swell bumps back up to 8ft on Wednesday, August 20, but the wind is a moderate cross-onshore at 12 mph, making it choppy and messy. That’s more likely to be a kite-surfing show than a paddle-in session.
Honestly, if you’re an experienced surfer who can handle a big, powerful reef with a bit of chop, the afternoon of August 11 or the morning of August 15 is your best bet. For everyone else, it’s a good time to wait for a better forecast.
Rusty, signing off.

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.
