The Lowdown
Alright mates, Rusty here. Let's break down the next couple of weeks of surf.
Honestly, this forecast is a bit of a bummer for us. The only spot we've got data for is Ketewel, a reef break tucked away on the sheltered side. Water temp is about 79°F, which is pretty average for this time of year, nothing special.
We start off on Sunday the 16th of August. Swell is a solid 7ft from the SSW, with a super long 16-second period – proper groundswell energy. But the wind is cross-onshore from the ESE at 9 mph, and that's going to mess up the surface, making it choppy and lumpy. The combined energy is strong at 1935. It's rideable but not clean. The afternoon drops a touch to 6ft but the same story.
The whole first week is a pattern of frustration. The swell is consistent from the SSW, but that wind just won't swing offshore. Monday the 17th, Tuesday the 18th, same thing. By Wednesday the 19th, the swell builds to 7ft in the morning and 8ft in the afternoon. The energy is pumping, hitting 3525 on Wednesday arvo, but that cross-onshore wind is still the enemy.
Thursday the 20th is the biggest day, with an 8ft morning swell. That’s expert territory for sure, especially with a 16-second period and a messy side-wind. The energy is massive at 3189. Friday the 21st the wind picks up to 12 mph, making it even choppier.
Honestly, for kitesurfers, this whole period is gold. Strong, consistent SSW swell with a steady side-wind is perfect for them. For us on a paddle board, it's a battle.
The second week, from the 21st of August onward, the swell hangs around but the wind refuses to cooperate. It stays cross-onshore most days. You might get a slightly cleaner look on the 23rd or the 30th when the wind switches to just 'on', but quality is going to be low.
There are no absolute standouts. The most powerful surf will be around the 19th and 20th of August, with that 8ft to 8ft SSW groundswell having serious grunt, but you'll have to fight the chop for it. For the classic, glassy Ketewel we all love, this 16-day forecast just doesn't have the right wind. We're waiting for a better window.
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.
