The Lowdown

Alright folks, Rusty here. Let's have a good hard look at what's on the table for Ketewel over the next couple of weeks.

Straight up, I gotta be honest with you: this is a tough stretch to call. We're looking at a solid run of surf, but the wind is constantly messing with the quality. It’s not often clean, and the best days are more about potential than perfection. The water temp is sitting at 80°F, which is bang on average for this time of year, so no surprises there.

The pattern starts with a bit of a whimper. Wednesday the 26th has some waist to chest-high swell (5 ft) from the SSW with a moderate period of 14 seconds, but that cross-onshore wind from the ESE is going to chop it right up. The energy reading is moderate at 844 (moderate wave energy) that morning. It’s not worth paddling out for.

Things get a little more interesting as we head into Thursday the 27th. The swell drops back a touch to around 4 ft, but look at that period jumping to 16 seconds, and the energy ramps up significantly to 1126 (moderate wave energy). By the afternoon, the wind goes light and *onshore* from the SSE, and the energy jumps again to 1651 (moderate wave energy). This is a long-period groundswell, which for a reef break like Ketewel could be really special. The wave shape could be lined up and proper. It’s a marginal call due to tide, but this is the first real window where you might get a clean one.

Friday the 28th is the big one on the charts. We’ve got a solid 8 ft SSW groundswell rolling in with a 16-second period. The wave energy is through the roof at 3026 (strong wave energy) in the morning. The wind is light from the SE in the morning. At 8 ft, this is going to be pushing into the too-big-for-beginners range, but for anyone comfortable on a bigger day, this is the standout of the whole outlook. It’s a proper pulse. The afternoon looks even better as the wind goes light and *onshore* from the south. This could be absolutely firing, but it’s still a “marginal” call on the tide. If you can get the tide right, this is your day.

From Saturday the 29th, the swell backs down a notch to 6 ft. Still a decent size, but the energy drops off to 1382 (moderate wave energy). The wind is light and onshore from the SSE, which is okay, but the magic of Friday will be gone.

Then we hit a bit of a slump. From Sunday the 30th through to Friday the 5th of September, it’s a stretch of poor to marginal conditions. The swell hangs around 4 ft to 5 ft, but the wind is consistently cross-onshore from the SE at 9-12 mph, keeping the surface messy and choppy. The energy readings drop into the 500 to 1200 range (weak to moderate wave energy). It’s a long week where you’re better off doing something else.

There’s another pulse on the charts for Sunday the 6th of September. Swell bumps back up to 6 ft-7 ft from the SSW with a 16-second period, and the energy is strong at 1864 (moderate wave energy). But again, the morning is cross-onshore chop. The afternoon improves to a light onshore wind, so maybe a session late in the day could be worth it.

The last interesting window is a week out, on Wednesday the 10th of September (over a week and a half from now). Swell is a solid 7 ft from the SSW with a 17-second period, pushing strong wave energy at 2845. And the wind goes light and onshore from the SSE. That’s a promising combo, but it’s a long-range call, so the details might change. I’d keep an eye on it.

Best Bet: Without a doubt, Friday 28th August is the standout. That 8 ft SSW groundswell with long 16-second intervals and light onshore wind is the most powerful, cleanest-looking window in the whole 16-day run. The crowds at Ketewel can be a thing sometimes, but on a day like this, the quality should thin the lineup out to those who know what they’re doing.

Second Look: Thursday afternoon 27th August and Wednesday 10th September are worth a look for the quality of the long-period groundswell, even if the size is smaller.

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.
