The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for Ketewel. It’s a reef setup, exposed to the swell, and you’ll want a south direction in the water to get the most out of it. The water temp is sittin’ right on 80°, which is pretty much dead average for this time of year, so no surprises when you get in.
Right now and for the next several days, it’s a tough watch. We’ve got a long period SSW groundswell running, mostly around 5ft to 6ft, but the wind is blowing cross-on from the southeast nearly the whole time. That’s wrecking the surface, making it choppy and messy. The energy in the water is strong (1882) but the quality just isn’t there. Saturday the 22nd through to the morning of Thursday the 28th is a stretch of poor to marginal conditions at best. You’d be paddling your heart out for sloppy, blown-out waves and that just ain’t worth it.
Now, things start to look a little more interesting from Thursday afternoon the 28th onward. The wind shifts around to a light onshore from the south-southeast, and the swell bumps up – Thursday morning the 28th we’re lookin’ at 8ft of SSW groundswell with a period of 16 seconds. That’s a lot of energy (3465) and with the wind only a light breeze, the surface should be cleaner. Keep in mind, at 8ft this is getting into expert territory – it’s a solid reef break and you’ll need your wits about you. That long period will also mean longer lulls between sets, which can help you get out the back, but the waves will be powerful and lined up.
Friday the 29th holds similar promise with 8ft swell and lighter winds, still onshore but light. The energy stays high (2610). This is probably the pick of the whole outlook – not perfect, but the best we’re gonna get. After that, through the weekend and into the start of September, the swell drops back under 7ft and the onshore cross-wind returns, taking the shine off things.
There’s a little pulse again around the 1st and 2nd of September with 6ft to 7ft SSW swell and a bit more energy (2351 to 2414), but again, the cross-on wind will keep it from being stellar. You might score a few if you’re keen, but it’s not a flat-out standout.
As for crowds – this spot can get busy, so if you paddle out on the better days, especially the 28th and 29th, expect some company.
Overall, the best bet in this 16-day window is the morning of Friday the 28th of August into the 29th. That’s the size, the power, and the cleanest wind we’re going to see. It’s a long way out, so keep an eye on it, but it’s got potential. Be warned: it’s an advanced wave and not for the faint-hearted at that size.
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.
