The Lowdown

Alright, Rusty here. Let’s have a look at what’s cooking for Ketewel.

Straight up, the next week and a half is a bit of a grind. We’ve got a solid, long-period groundswell from the SSW rolling in, but the wind is the story – and not a good one. For the first stretch, from Wednesday the 19th right through to the morning of Wednesday the 26th, it’s a constant cross-onshore breeze, mostly from the SE, keeping the surface chopped up and messy. The wave energy is moderate to strong – you’re looking at numbers like 3073 on Wednesday morning – but the wind state means it’s gonna be bumpy and hard to enjoy.

Ketewel is a reef break, so it needs clean conditions to shine, and it’s simply not getting them for most of this run. The swell sits around 5ft to 8ft, with periods mostly in the 15 to 18 second range – that’s proper groundswell energy, but it’s being wasted. On Friday the 21st, the swell drops a touch to 6ft, but the cross-onshore is still there, so it’s marginal at best. Thursday the 27th afternoon shows a brief drop in wind to just a light breeze from the SSE, with a clean 3ft swell and a very long period of 19 seconds – that’s a hint of what could be, but the energy is still weak (1170).

The water temp is sitting at 80°F with an anomaly of just 0.5°F – about as average as it gets for this time of year.

The real stand-out window doesn’t arrive until Friday the 28th of August. Morning brings a light cross-onshore breeze, which is a big improvement, and the swell kicks back up to 7ft from the SSW, period 16 seconds. The wave energy jumps to 2384 – solid, moderate strength. It’s still not perfectly offshore, but it’s the cleanest and most powerful the reef will see in this whole run. The wind is light enough that the surface should have just small ripples, making it far more surfable than anything before it.

After that, conditions slowly fade again. Saturday the 29th morning still holds some hope with light winds and 5ft swell, but by the afternoon the breeze picks up and the quality drops. The end of the run, into early September, brings another bump in swell on the 31st and 1st, with a very long period of 20-22 seconds and wave energy up over 3000, but once again it’s cross-onshore, chopping up what could be a beautiful wave.

If you’re going to paddle out, make it Friday the 28th of August. That’s your best shot. The rest is mostly frustrating, especially for a reef that needs a clean face. The inconsistent nature of Ketewel doesn’t help either – when the wind’s on it, there are better places to be.

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.
