The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for the next stretch.
Right now, the vibe is a bit frustrating. The best bet we’ve got is Ketewel, a sheltered reef setup that demands an advanced skill level. It’s inconsistent, so you’ve got to be patient. The water temp is sitting at 81°, which is about average for this time of year. The first few days are a write-off for quality surfing – the wind is on it or cross-onshore, the swell is messy, and the wave energy is weak. You’ll see a bit of a pulse building from the 6th of August onward, with a long-period groundswell from the SSW, but the wind keeps it choppy and the conditions are only marginal at best.
The standout window opens up around the 10th of August, Monday afternoon. We’ve got a solid 8ft SSW groundswell with a very long period of 18 seconds rolling in, and the combined energy hits a strong 3915. The wind goes onshore, which is a big plus for clean faces. This is a proper point-break-style swell that should line up nicely at this reef. The following days, the 11th and 12th, keep the size in the 8ft to 7ft range with a similar long period, but the wind stays cross-onshore, so it’s a bit less perfect. The 13th of August Thursday morning gets even bigger, with 10ft SSW swell and a very long 18-second period, and the energy is absolutely pumping at 5584. That’s a serious groundswell – it’s going to be powerful, fast, and heavy. The wind is still cross-onshore though, so it’ll be a bit lumpy. This one is only for experts. After that, conditions taper off into the second week, with the wind picking up and the quality dropping. The 15th and 16th are poor, choppy, and not worth the paddle.
Overall, your best bet for a clean, standout session is the 10th of August, Monday afternoon at Ketewel. That window of onshore wind with a big, long-period swell is the pick of the bunch. The 13th is huge but rougher. Don’t get your hopes up for the first week; it’s a waiting game.
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.
