The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the table for Ketewel over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. We’ve got a solid run of days with no real quality surf on the cards. The first few days are a write-off. We’re looking at a good 8 or 9 day gap before anything even starts to look interesting. The swell is there, no doubt, with a long-period SSW groundswell, but the wind is just a constant issue. It’s nearly always cross-onshore from the southeast, which is killing any chance of clean faces.
The first time we get even a hint of something worth paddling out for is on Sunday the 20th of September. The morning shows a 7 ft SSW swell with a 17-second period – that’s proper long-period groundswell, packing some serious energy (2291). The wind is light from the southeast, and it’s actually onshore. That’s not ideal, but for this reef break, it’s a big step up. The water temp is a warm 80°F, which is pretty much bang on average for this time of year. Still, the forecast calls it marginal.
Then, the real standout window looks like the 23rd of September. Wednesday morning we see a 7 ft SSW swell with a 16-second period and a combined energy of 2495 – that’s a proper pulse of energy. The wind is still cross-onshore from the SE, but this is the biggest, most powerful swell of the whole outlook. For the advanced crew, this could be the one to circle. The afternoon keeps similar size and power. This is big for the spot, over 7 ft, so definitely not one for the beginners – this is expert territory only, especially on a reef break like Ketewel. It’s also worth noting the swell direction is SSW, which is exactly the optimum direction for this sheltered spot. The crowds can sometimes be an issue here, but with conditions like this, there won’t be many out.
After that, the swell backs off a touch into the 24th and 25th, but stays in the 5 ft to 6 ft range, with that long-period quality fading. The 26th of September has a really interesting blip: a 3 ft swell, but with a 19-second period. That’s a very long period for such a small wave, which could give you some really lined-up, glassy walls if the wind plays ball.
So to wrap it up: the first week and a half is a total non-starter. The standout is the 23rd of September, with that powerful SSW groundswell. For the experts, that’s the day to be looking at, but it’s still a long way out so keep an eye on the wind forecasts.
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.
