The Lowdown

Alright, Rusty here, and I’ve got a look at what’s coming down the line for us. The water’s sitting at a warm 81°F, and that’s pretty much spot on for this time of year, so no surprises there.

The pick of the bunch, and really the only break that’s made the cut, is Ketewel. It’s a reef setup, and it’s a bit inconsistent, so you’ve got to be patient. This one is for the advanced crew—when it’s on, it’s a proper wave, but it’s not a place for learners.

We’ve got a bit of a slow start. The first real window is Wednesday, August 5th. Wednesday afternoon looks promising with a clean 5 ft SSW swell, a period of 15 seconds, and light offshore winds from the SE. The energy is moderate at 1486, and with that offshore wind, it should be glassy. But it’s a marginal forecast, and we have to be honest about that.

Thursday, August 6th, gets a bit more size, but the wind swings cross-onshore, and the conditions get choppy. Friday the 7th is similar. The swell builds through the week, hitting 8 ft by Friday afternoon, but the cross-onshore wind keeps it from being clean. The energy is climbing, but it’s not lining up.

Saturday, August 8th, and Sunday, August 9th, are still messy with rain showers and cross-onshore winds. The swell is around 7 ft to 7 ft, but the quality just isn’t there.

Now, Monday, August 10th, is where things get interesting. Monday morning sees a 6 ft SSW swell with a long 19-second period, and the energy jumps to 4192. The wind is light offshore from the SE, which is a big positive. But the forecast is still marginal. Monday afternoon, the swell jumps to 10 ft, same long 19-second period, and the energy is a solid 6139. That’s strong energy, but at 10 ft, this is strictly for the experts. The long period means it’s a groundswell, and at a reef like Ketewel, that could be something special. The wind is offshore, so it should be clean. This is the standout.

Tuesday, August 11th, keeps the 10 ft swell, but the period drops to 17 seconds. Still big, still for experts, and the wind is offshore in the morning. The energy is 4832. It’s a solid session if you’re up for it.

The rest of the week goes a bit quiet again. The wind turns cross-onshore on Wednesday, August 12th, and the swell drops. Thursday, August 13th, sees a 10 ft S swell with a 17-second period and a light offshore wind in the afternoon. That’s another expert window, but the forecast is still marginal.

The following week, from August 14th onward, the swell stays around 8 ft to 10 ft, but the wind is mostly cross-onshore. There’s a big energy spike on Tuesday, August 18th, with a 10 ft SSW swell and 18-second period, energy at 6013, and a gentle cross-onshore breeze. It’s a promising one for the long-range, but it’s less certain.

Overall, Monday, August 10th, is your best bet. That big, long-period SSW groundswell with offshore winds is the standout. After that, you’ve got a few other big days, but the wind is the limiting factor. Ketewel is a reef, so that long-period swell should really wrap in and give some proper barrels. Just be ready for the inconsistency.

Rusty, signing off.

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.
