The Lowdown

Alright, Rusty here, let’s chew over what’s shaping up for the next couple of weeks.

Well, to be honest, it’s a bit of a frustrating stretch on the whole. We’ve got swell, no doubt about it, but the wind just isn’t playing ball for most of the run. The water is sitting at a warm 80°, which is pretty much bang on normal for this time of year, so you won’t need a steamer, that’s for sure.

The pick of the bunch, and it’s the only one I’d really get excited about, is the Friday morning session, August 21st, at Ketewel. It’s a sheltered reef set-up, so it needs a bit of love. We’ve got a solid 6ft SSW groundswell running with a very long 15-second period, which packs a real punch – the combined energy is up there at 2253. The magic ingredient is that light 6 mph SE breeze, which is blowing straight offshore. That’s going to groom those waves to perfection. Keep in mind, this spot is an advanced wave and it’s inconsistent, so you’ll need to be patient and on your game. The crowds can show up sometimes, but with that quality, it’s worth the company.

The rest of that first weekend and into the following week, it’s a real shame. The swell stays strong, but the wind swings cross-onshore, turning it all to chop. Saturday the 22nd has a 7ft SSW swell, but with 12 mph cross-offshore wind, it’s just a mess. That’s a solid 7ft, which is pushing into expert territory, and with the wind howling, it’s more of a kite-surfing show than a paddle-in session.

From Tuesday the 25th through to the end of the month, it goes flat and quiet. The wave heights drop under 5ft and the energy fades, with no real standouts. It’s a proper gap of about 5 days with nothing to recommend.

Then, looking ahead, we get a bit of a pulse again as we roll into September. The mornings of the 1st and 2nd of September show some promise. We’re looking at a 7ft to 7ft SSW swell with a very long period of 17–19 seconds, and the energy is strong again (2728 and 2682). The wind is forecast to be light and offshore, which is a big plus. It’s a long-range call, so keep an eye on it, but it could be the best run of the whole outlook if it holds together. The size is definitely for the experienced crew only, but the quality could be there.

All in all, Friday morning is your best bet. The rest is a waiting game.

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.
