The Lowdown
Alright folks, Rusty here, checking in on the local scene.
Overall, it’s a bit of a frustrating run for us. We’ve got some solid swell energy on the way, but the wind is going to be a real pain for most of the forecast. We’re looking at a lot of clean-looking lines getting chopped up by onshore breezes. The water’s sitting at a pretty typical temperature for this time of year, nothing wild going on there.
Let’s start with the only real game in town. We’ve got the Ketewel reef break. Through Friday the 28th and Saturday the 29th, the swell is pumping. We’re talking a very strong 8ft (3043 energy) dropping to 6ft (1382 energy) a couple of days later, with a long-period, 16-second SSW groundswell. That combo has serious power. However, the wind is a tragedy. It’s onshore and cross-onshore from the S and SSE, blowing at 9 to 12 mph which is going to leave it choppy and messy. This is more of a kite-surfing setup for those days, honestly.
Sunday the 30th and Monday the 31st, the swell drops right off. We’re down to 4ft of weak to moderate energy, with a very long 18-second interval. That kind of period can make a beachy section like this a bit straight. The cross-onshore wind is still a problem, so I’d give these days a miss.
Now, here’s where it gets interesting for the hardy ones. From Tuesday the 1st of September through to Thursday the 12th, the swell stays in that 5ft to 8ft range, with moderate to strong energy readings. The standout is the period around Saturday the 12th of September. The morning shows a powerful 8ft swell (4604 energy) from the SSW, riding an 18-second period. That’s a lot of water moving. The wind is still cross-onshore from the SE at 9 mph, so it won’t be perfect. Given the size, over 8ft, this is for experts only. For a couple of days before that, like Thursday the 11th, we have an 8ft SSW swell with a 16-second period. The energy is high (2950), but again, the wind is messing with the surface. It’s marginal, but the size is there for someone who doesn't mind the chop.
Honestly, the best chance for something semi-decent looks like the tail end on Saturday the 12th. It's a long way off, so call it promising but not a sure thing. Between now and then, we're looking at a long gap of days that are just not worth paddling out for.
Stay tuned, forecasts can change.
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.
