The Lowdown

G’day, I’m Rusty, and I’ve been staring at the charts for your local zone. Let’s be straight with it – for the next week and a half, Ketewel (a reef setup) is a tough nut to crack. The wind is mostly coming out of the southeast, which for this sheltered spot is a cross-onshore breeze, and that’s making the surface messy. The water is sitting at 81°, which is bang on average for this time of year, so at least you won’t be shivering while you’re getting frustrated.

The combined swell energy is pushing some serious numbers – we’re talking between 673 and well over 3000 (moderate to strong energy) – but it’s all coming from the SSW, which is a bit off the optimum direction for this break, and the period is often on the shorter side. That means the power is there, but the shape is going to be sloppy. The first few days are a write-off for a proper surf. Friday 4th September is a total strikeout – poor surf conditions and a cross-on breeze. Saturday 5th and Sunday 6th are only marginal, with the swell bumping up to 6ft to 7ft, but that cross-onshore wind and a period of 14-16 seconds means it’s going to be a choppy, frustrating paddle.

The real standout, if you can call it that, is the middle of the second week. Tuesday 8th September morning sees a 5ft swell from the SSW with a 19-second period (very long-period groundswell). That’s a lot of energy (2712) and the wind is onshore, but light. For a reef like Ketewel, that long period could draw some nice lines, but it’s also prone to sucking the water out and making the sets irregular. The best chance for a decent wave is Wednesday 9th September afternoon: 7ft of SSW swell, 16-second period, and a light S breeze pushing onshore. The score is the highest of the whole run, and the combined energy is strong (2368). It’s still marginal, but it’s the pick of a very average bunch.

After that, we’re back into a run of poor and marginal conditions through to the end of the 16-day window. The wind stays cross-onshore, and the swell hangs around 5ft to 8ft, but it’s never clean. Crowds are listed as “sometimes” at Ketewel, so if you do paddle out on that Wednesday, you might have a few locals to share the lumps with. If you’re an advanced surfer who can handle an inconsistent reef with a bit of chop, that Wednesday afternoon is your best bet. For beginners, that 7ft is too big, and the conditions are too tricky. Honestly, this setup looks more interesting for a kite surfer looking for wind than a paddle surfer chasing perfection.

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.
