The Lowdown

Alright, folks, this is Rusty. Let’s get straight into it. We’ve got a 16-day window here, but don’t get excited too quick. The start of this run is a bit of a write-off, honestly. We’re looking at a lot of days with poor surf conditions and ratings that tell me to stay on the sand. The wind is nearly always cross-on or onshore from the southeast, making a mess of things. We’re talking about a solid 10-day stretch of "meh" at best before things start to look a little more interesting.

The first real glimmer of hope pops up around Sunday, September 8th. Ketewel starts showing some life, but it’s still marginal. The swell energy is building, hitting a combined energy of 2283 on the morning of the 8th, with a long-period 4ft swell from the SSW at 19 seconds. That’s a proper groundswell, but with the wind still onshore from the SSE, it’s gonna be rough. The afternoon sees a 6ft swell with a period of 18 seconds and energy at 2947, but again, it’s a cross-shore wind. Not a day to write home about.

Come Monday, September 9th, we’re getting closer. The morning sees a 7ft SSW swell at 16 seconds and combined energy of 2474. The wind is a light cross-on from the S at 10 km/h. It’s still not glass, but it’s the best we’ve seen. This might be the best chance for a paddle if you’re an advanced surfer and don’t mind a bit of texture on the face. But for the level of surf we expect, it’s still just "marginal." The afternoon drops a bit with a 7ft swell.

Now, if you’re a patient surfer, the standout is the period around Tuesday, September 10th, through Wednesday, September 11th. On the 10th, we get a 6ft swell from the SSW at 15 seconds in the morning (energy 1399), and by the afternoon it’s 6ft at 16 seconds (energy 1554) with a light 10 km/h SSE wind. That’s about as clean as it gets in this forecast. It’s still not perfect, but the light breeze will keep the chop down. Best on the cards is probably the morning of September 11th: 5ft SSW swell at 15 seconds, energy 1629, and the wind is onshore but light. For a reef break that’s inconsistent and best for advanced crew, this is the time to be in the water.

After that, it tails off back into marginal conditions or poor surf from the 12th to the 18th. The swell sticks around in the 4ft to 7ft range, but the wind stays mostly cross-on from the SE or ESE, keeping it choppy. The energy drops back down to the 900-2300 range, which is moderate to strong, but without good wind, it’s just a messy ocean.

Overall, for this region at Ketewel (Bali), the conditions are a struggle. If you’re desperate for a wave, the 9th through the 11th of September are your window, with the morning of the 11th being the cleanest bet. But don’t expect perfection – it’s a tough forecast. All the long-period SSW swell is great for the reef setup here, but the wind is the enemy. The water temp is right around average for this time of year, so no surprises there.

Keep your head up, the run of poor conditions won't last forever, but for now, it’s a waiting game.

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.
