The Lowdown
G’day, Rusty here. Let’s be straight up – it’s a tough run of surf ahead for Ketewel. The outlook is pretty flat for the first few days, and what swell does show up is fighting a messy onshore wind. There’s a promising pulse right at the tail end, but we’ve got a long wait.
The first surf worth mentioning doesn’t fire until Saturday the 13th of August, so that’s a solid two-week gap with nothing but marginal or poor conditions. For the first week, from Thursday the 30th of July right through to Wednesday the 12th of August, it’s all cross-onshore breezes from the SE and ESE, mostly 12-13 mph, putting a chop on the surface. Swell hangs around 4ft to 6ft from the SSW, with periods between 14 and 18 seconds – that’s proper groundswell, but it’s hitting this sheltered reef with poor shape. The combined energy sits between 1074 and 2760 (moderate to strong wave energy), but it just doesn’t matter with the wind ruining it. This spot is a sheltered reef, and with the swell coming from the SSW and the optimum direction being S, it’s not a great angle either. Plus, it’s an inconsistent break, so don’t expect much.
Now, let’s talk about the standout. The real hope comes on Thursday the 13th of August afternoon and Friday the 14th. On Thursday afternoon, we see a jump to 8ft SSW swell with a very long 20-second period, and the combined energy rockets to 5454 (very strong wave energy). Friday morning pushes even higher: 10ft SSW swell, 18-second period, and an energy reading of 6201 (very strong). The wind finally swings offshore – light breezes from SE and S, which will keep the surfaces glassy or clean. This is the window. For a reef break like Ketewel, that long-period SSW groundswell at over 8ft is expert territory only. Beginners, stay out. The water temp is sitting at 81°F with a 1°F anomaly, which is about average for this time of year.
Keep in mind, this is a long-range call – things can change – but if it holds, Friday the 14th morning is the best on offer: 10ft of clean, long-period SSW swell at a sheltered reef. It’s an inconsistent spot, so patience is key, and crowds are possible here. If you’re an expert and you can wait, that’s your day.
This is 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.
