The Lowdown
G’day, Rusty here.
Well, I’ve gotta be straight with you – the next couple of weeks at Ketewel look like a write-off. There’s no surf worth paddling out for right now, and the forecast shows a long stretch of poor conditions. The first decent wave energy doesn’t show up until the morning of Monday the 20th of July, and even then it’s a mess.
The overall pattern is a constant, annoying cross-onshore wind from the ESE or SE, blowing at 9 to 12 mph, which keeps the surface choppy and messy. The swell is mostly from the SSW, with moderate energy readings (around 2267 on Monday morning), but the combination of wind and swell direction doesn’t work in our favour.
From Monday the 20th through to the end of the first week, the surf is either “marginal” or “poor” – that’s nine days straight of nothing to get excited about. The swell does bump up to 7 ft on Monday afternoon, but it’s still cross-onshore and choppy, and the water temp is sitting at 82°, which is about 2° warmer than usual for this time of year – a bit of a warm anomaly.
Into the second week, the same story continues. The swell drops off, the wind stays onshore, and the wave heights linger around 3 ft to 5 ft. The period on some days stretches to 17-18 seconds, which is a proper long-period groundswell, but with the wind ruining it and the direction being all wrong, it’s just a tease. There’s a brief moment on Saturday the 1st of August afternoon where the score nudges up to a marginal 1, with 5 ft SSW swell at 17 seconds and a gentle breeze, but it’s still cross-onshore and fairly choppy – not worth the drive.
The problem is that Ketewel (a reef break for advanced surfers) is inconsistent and sheltered, and it needs a clean offshore wind from the NNW to really shine. Right now, we’re getting the opposite, and the optimum swell direction is from the south, but the wind is just ruining the surface. The combined energy readings are moderate to strong (three-digit and four-digit values), but with no clean wind, it’s irrelevant.
There’s no standout session in the whole 16-day window. This is a blank run – that’s the reality. The setup here looks more interesting for kite surfing than paddle surfing, given the consistent cross-onshore wind and moderate swell.
But hey, Ketewel is a spot that can deliver when it’s on, and forecasts can change. For now, I’d leave the board on the roof and wait for a better window.
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.
