The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on offer for the next couple of weeks.
Honestly, it’s a tough stretch for Ketewel. The wave energy is there, but the wind is just a constant pain. We’re looking at a solid 16-day window, but the first real chance to paddle out doesn’t come until Monday, July 20th, and even then it’s a grim one. The whole run is plagued by cross-onshore winds, mostly from the SE, which is going to chop everything up. There’s a long gap of poor surf conditions from Tuesday the 21st all the way through to the end of July, with no real standouts. The only flicker of life comes right at the very end of the forecast.
Let’s break it down. On Monday afternoon, July 20th, we get a wave that’s 7 ft from the SSW with a very long 16-second period. That’s proper groundswell energy (2042), but it’s blowing cross-on at 12 mph, so it’s going to be a messy, choppy affair. The water is a warm 81°, which is about average for this time of year. Not worth a session, in my book. The next couple of weeks are a washout of poor surf conditions, with that same cross-on wind messing up every swell.
Now, look, this is a reef break that’s sheltered and inconsistent, so it needs the stars to align. The cleanest potential we see is a long way off, on Thursday, July 30th. The morning shows a 4 ft SSW swell with a 16-second period and a light breeze (6 mph). The energy is moderate (1132). The afternoon bumps up to 5 ft from the same direction with a 15-second period and even stronger energy (1297). The wind is still cross-on, but it’s light, so it’ll just put a few ripples on the surface. The water temperature is still expected to be warm. These are the only two sessions in the whole 16 days that I’d even call “marginal,” and they’re the best you’ll get. The swell is still a bit too big for beginners, and the direction is from the SSW, which isn’t the optimum S direction for this spot, but it's as close as we’ll get.
The rest of the first week of August continues the same story: persistent cross-onshore winds and poor conditions. There’s a 5 ft SSW swell on Tuesday, August 4th, with strong energy (1556), but the wind is still on it, so it’s a no-go. This place is inconsistent at the best of times, so a blank run like this is more normal for the area. It’s a real shame, but the wind just won’t play ball.
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.
