The Lowdown
Alright, Rusty here again, translating that into feet and Fahrenheit.
Surf's been mostly average, but there’s a sneaky good one coming. The water temperature’s about 81° right now at Ketewel, which is normal for this time of year, so no surprises in your boardies.
For most of the next week plus, the swell comes from the South-Southwest, but that southeast wind just won’t let up, blowing cross-onshore and making everything messy. The swell period isn't short — it’s 13 to 18 seconds — but the chop is bad. Don’t bother for a while.
September 5th things calm a bit wind-wise, but the surf is still just borderline. The standout is September 9th afternoon. That’s the one. The swell gets up to about 8ft, with a 16-second period and the combined energy reading is 5120 — that’s a pumping signal. The wind is barely a breeze, straight onshore but so light you barely notice. This is groundswell, and on Ketewel’s reef it’s going to have some proper shape and power. At this size, it’s for the advanced crew only. The crowds are only *sometimes* an issue, so you might get it with only a couple of friends.
The days leading up to and after that hold some solid 6ft to 8ft swell with light winds, but nothing tops that Wednesday. September 9th afternoon is your golden window.
Rusty out.

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.
