The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – the outlook for Ketewel over the next 16 days is a tough one. This is a sheltered reef setup that needs just the right conditions, and right now, it’s just not getting them. The entire forecast period is a write-off for decent surf, with a solid two-week stretch of poor conditions starting from Thursday, the 16th of July, all the way through to Friday, the 31st of July. There’s no standout day, no sneaky window – just a long, frustrating gap.
The trouble is that persistent cross-onshore wind from the ESE and SE. It’s not brutal, but it’s a constant 12 to 15 mph breeze, and that’s keeping the surface choppy and messy every single session. The swell is coming from the SSW, which is out of the optimum S direction for this break, and while it’s a long-period groundswell – 15 to 16 seconds – that usually means good energy, the wind is just killing it. The combined swell energy is moderate at best, with values hovering around 966 to 1126 in the first few days, but it’s always paired with “poor surf conditions.” Even when the swell bumps up to 7 ft on Monday, the 20th of July, the energy reads 2364, which is strong, but the wind is still cross-on, and the “marginal” note is hardly a vote of confidence.
On Monday, the 27th of July, the swell direction shifts to the SE, but the period drops to a short 8 seconds, so you’re getting weak, windswell-like waves with no shape. The energy is still moderate (685 to 777), but the short period means it’s just not going to line up well on this reef. A few days later, on the 30th of July, the period bumps back up to 19 seconds from the SW, with energy around 1098, but again, it’s all poor and cross-on. Ketewel is a break that’s already inconsistent, and this kind of persistent wind is a killer. There’s no glassy morning, no offshore window – just a constant cross-on breeze that’s ruining what could be a fun, long-period swell.
Honestly, for a surfer, this is a blank run. The wind is too strong and from the wrong angle, and the swell direction is never quite right. With the break being a reef and inconsistent, it’s not worth paddling out. If you’re a kitesurfer, that steady cross-on 12 to 15 mph might be interesting, but for a paddle surfer, you’re better off giving it a miss. Forecasts can change, but right now, the 16-day window is a washout.
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.
