The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
To be straight with you, the outlook for Ketewel (Indonesia) is a tough one. The models are showing a persistent onshore wind pattern for most of the period, which is just going to keep things messy. The swell is there, but it’s not lining up right. We’ve got a solid, long-period groundswell from the SSW running through the whole window, but with that constant wind, it’s going to be hard to find a clean wave. The water temp is sitting at 80°, which is about average for this time of year, so no dramas there.
We’re looking at a run of marginal surf, with the first real chance of anything decent not showing up until Tuesday the 8th. Even then, it’s a bit of a gamble. The best on offer is shaping up to be Wednesday the 9th of September. We’ve got a decent 7ft to 8ft SSW swell rolling in, with a period of 16 seconds, packing a lot of energy (2829 on the energy scale). The wind is the key – it’s a light breeze from the S, which is onshore, but it’s the lightest it’s going to be. This is a reef break, so that long period should wrap in nicely, but it’s inconsistent and only for advanced surfers. Expecting crowds here, as it’s a well-known spot, but with the wind, it might keep a few away.
After that, we slide back into a groove of onshore breezes and cross-onshore chop. The wind stays stubbornly from the SE and SSE, ruining the shape of a 5ft to 7ft SSW swell. There’s a day on Monday the 14th that looks completely blown out, and a poor few days following. The energy stays moderate, but the quality just isn’t there for a paddle surfer.
The second week doesn’t offer much hope. The wind remains onshore or cross-onshore, and the swell is still there but messy. The best of a bad bunch might be Saturday the 19th, but again, it’s cross-onshore and choppy. It’s a long-range call, so don’t plan your trip around it. For this stretch, the surf is barely worth a look.
Overall, it’s a classic case of the swell being present but the wind being a total buzzkill. Ketewel needs a bit of offshore magic to come alive, and we just aren’t getting it. For the next two weeks, I’d be looking for a different hobby or a spot that handles the onshore wind better. The setup looks more interesting for kite surfing than paddle surfing for most of this period.
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.
