The Lowdown
Hey, Rusty here again, this time in feet and miles per hour. Lookin’ at Ketewel for the next 16 days, and I gotta say, it’s a rough outlook. There’s no standout session in the whole forecast period. The wind’s gonna be a persistent cross-onshore mess, and the swell angle is just off for this sheltered reef.
Starting Saturday, 12 September, the combined swell energy is already strong at 1475, but the wind is blowing 9 mph from the SE – cross-on – and the waves are labeled “poor”. That sets the tone. Swell heights run from about 5 ft to 7 ft, all from the SSW, with periods between 14 and 18 seconds, so there’s some long-period groundswell in there, but it’s all chopped up by the wind. Even on the 20th of September, when the swell hits 7 ft and the energy is over 2200, the wind’s still cross-on or onshore. Just “marginal” at best.
Late in the run, on Saturday 26 September afternoon, the swell drops to 3 ft but the period jumps to a very long 19 seconds – real clean groundswell energy (907) – but the wind switches onshore, and it’s “poor”. No dice.
Into the second week, from the 20th onward, nothing changes. Swell stays 5 ft to 7 ft from the SSW, wind hangs in from the SE or ESE at 6 to 9 mph. The energy stays moderate to strong (1400 to 2000), but that cross-on flow ruins it. The 23rd of September morning shows 6 ft with energy at 2054, but again, cross-on.
The water temp is a comfy 80°, about average for the time of year. But for a surfer, the whole 16 days is a wash. The wind and swell angle just don’t line up for this spot. If you’re into kiting, the steady cross-onshore breeze and solid wave heights might be fun, but for paddle surfing, it’s a blank stretch. That’s normal for this area sometimes.
Keep an eye on it, forecasts can turn.
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.
