The Lowdown
Right, let’s get into it. This is Rusty, and I’m looking at the surf outlook for Ketewel over the next 16 days.
Honestly, straight up, it’s a tough run. This reef break is a sheltered setup, preferring a southerly swell direction, and we’ve got that, but the wind is the real killer here. The whole period is plagued by a persistent cross-onshore breeze from the ESE/SE, which has the surface chopped up and messy. It’s not a good look for a wave that needs clean conditions to shine.
The first few days, from Sunday the 26th through to Wednesday the 29th, are just poor. We’re looking at a moderate breeze and choppy, ugly surf. Swell height is around 6 ft to 7 ft on the Sunday, dropping to 3 ft by Tuesday, but the wind makes it unrideable. The combined wave energy is moderate, around 884 (Sunday) to 854 (Wednesday), but it’s all wasted energy.
Then we get into a long stretch of marginal conditions. Thursday the 30th through to Saturday the 9th of August is a gray area. The swell is there, mostly from the SSW, with periods getting long – up to 17 seconds. That’s long-period groundswell, which is powerful, but it’s prone to breaking too straight here at a beach/reef setup. The wave energy gets strong, hitting 1322 (Thursday) and up to 1702 (Sunday), but it’s still mostly cross-onshore or onshore. The wind eases a little, becoming a light to gentle breeze, but the chop is still there. The commentary says “marginal surf forecast or questionable tide conditions,” which is a polite way of saying it’s not worth paddling out for.
The best, and I mean the only real standout, is the very end of the period. Monday the 10th of August morning has a 8 ft SSW swell with a 16-second period, and the offshore wind direction is “on” – meaning it’s blowing straight offshore. That is a massive game-changer. The combined energy is huge at 5527, which is very strong. This is a true expert-only wave. For a reef break, a clean 8 ft SSW groundswell with offshore wind is a dream. But it’s a long way out, so treat it as a promising but less certain call. The crowds are “sometimes” at Ketewel, so you might get a few on it.
For the rest, it’s pretty grim. The lack of clean, rideable waves means this setup looks more interesting for kite surfing than paddle surfing for most of the window. The water temperature is about average for the time of year. We’re looking at a long gap of almost two weeks before that one glimmer of hope on the 10th.

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.
