The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s gonna be a rough start. For the next several days, we’re looking at poor surf conditions with a persistent cross-onshore wind that’s got the surface all chopped up and lumpy. The swell is there, but the wind is just ruining it. We’re looking at a solid 4 to 5 days of very little to no real quality surf.
The first real glimmer of hope doesn’t show up until Friday the 31st of July. For the afternoon session at Ketewel, we see a light cross-onshore breeze and a 4ft SSW groundswell with a period of 17 seconds. That long period will bring some energy, but it’s still a bit of a gamble with the wind direction. The combined swell energy is moderate at 1174.
The best bet in this whole forecast, and the one to circle on your calendar, is Saturday the 1st of August. The afternoon at Ketewel is looking like a standout. The wind shifts to an onshore direction, but it's a light breeze at just 6 mph, so expect glassy conditions. The swell is a solid 5ft from the SSW with a very long period of 18 seconds. That’s a proper groundswell. The combined energy is strong, hitting 1595. This is the pick of the bunch, but keep in mind it’s a reef break and it’s inconsistent, so you’ll need to be patient and know what you’re doing. It’s also an advanced wave, so leave the foamies at home. The water temp is about average for the time of year.
Sunday the 2nd of August is another option with a similar setup. The swell bumps up to 7ft from the SSW, but it’s a bit more crossed-up. The wind is a gentle cross-onshore, so it won’t be as clean as Saturday. The energy is strong, at 2359 in the morning. This size is getting up there, so it might be a bit too much for beginners.
After that, the second week looks promising but less certain. We’ve got a couple of mornings with onshore winds and gentle breezes, like Tuesday the 4th and Wednesday the 5th, with 6ft to 5ft SSW swell. The energy stays moderate. The real heavy stuff doesn’t kick in until Sunday the 9th of August, when the swell jumps to 8ft from the SSW, and then 10ft on Monday the 10th. That’s expert territory only. The energy is very strong, over 4000. If you’re a pro, keep an eye on the 9th and 10th for a proper big-wave session, but the wind needs to play ball.
Rusty out.

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.
