The Lowdown

Alright, this is Rusty. Let's have a look at what's coming up for Ketewel over the next couple of weeks.

First off, I’ve gotta be straight with you. Right now and for the next several days, it’s looking pretty grim. We’ve got a solid SSW swell running, with wave heights around 6 ft and a long 16-second groundswell period – that’s got some serious energy behind it, clocking in at 1479 on the combined energy scale. But the wind is the killer. It’s been hammering from the SE at 12 mph, putting a nasty cross-onshore chop on everything. The water temp is sitting at 80°, which is about average for this time of year. This setup is just messy and blown out. Honestly, the conditions are poor, and it’s not worth paddling out.

Things start to get a little more interesting around Thursday, August 27th. The wind starts to ease and turn more onshore, but it's light enough that it might clean up slightly. We’re still dealing with a big, long-period swell – that Thursday afternoon sees a 3 ft swell from the SSW with a very long 20-second period and a combined energy of 1647. That’s a lot of power for a small wave. The issue is the tide. It’s marginal at best, so you’d be hunting for the right hour. Not a standout, but a glimmer of hope.

Now, if you can wait, the best window appears on Friday, August 28th (morning). The swell jumps up to 8 ft from the SSW, still with that lovely 16-second period, and the combined energy surges to 3065 – that is proper, strong wave energy. The wind is light and onshore from the SSE at just 6 mph. For a reef break like Ketewel, which is sheltered and needs that SSW sweet spot – and the guidance says optimum is from the S – this is close. The size is going to be too much for beginners, but for you advanced guys, this is the pick of the forecast. It’s still a bit marginal on the tide, but that’s the closest we get to a good session in this run.

After that, the swell backs off a touch, but we get a long stretch of onshore to light onshore winds and moderate energy, with a few afternoons showing a score of 2. The 31st of August (Monday afternoon) sees another pulse with a 6 ft swell, but that 19-second period makes it a bit tricky for a beach setup – those long-period groundswells tend to close out and are better on the reef, so Ketewel could handle it.

Into the first week of September, the pattern holds. Swell hangs around the 5 ft to 7 ft mark, with periods from 14 to 16 seconds. Winds stay SE, mostly 9 mph, keeping things cross-onshore and choppy. It’s not terrible, but it’s not clean. The 6th and 7th of September show some promising 6 ft to 7 ft swells with light winds from the S and SSE, but the scores are still just a 1. It’s a long-range promise, but nothing solid enough to call a standout.

So, to sum it up: the first few days are a write-off. The only real highlight in the whole 16-day window is Friday morning, August 28th. If you’re an expert and you can work around the tide, that 8 ft SSW swell with light winds is your best bet. Everything else is either blown out or marginal.

Stay tuned, and keep an eye on the forecast. Things can change.

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.
