The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

Right off the bat, we’ve got a solid stretch of good, clean swell coming through, but it’s not all plain sailing. The water’s sitting at a balmy 81°, which is pretty much normal for this time of year, so no surprises there.

The only break on the radar is Ketewel, a sheltered reef setup that really needs the swell from the south. The first few days are a write-off, I'm sorry to say. Tuesday the 1st through to Thursday the 3rd look basically unsurfable with a cross-onshore wind messing things up. The swell is there, but the wind is just killing it.

Things start to look a bit more promising from Friday the 5th onwards. The wind swings around to a more favourable onshore direction, and the swell is solid. It’s a bit of a mixed bag, but the standout window really looks like Wednesday the 10th and Thursday the 11th. We’ve got a decent 6ft to 7ft SSW groundswell rolling in with a long period of 16 to 17 seconds. The wind is light and onshore, which should keep things reasonably clean. This is a reef break, and with that long period, the sets will be proper and well-defined, though you’ll want to be ready for the lulls between them. The wave energy is strong, hitting over 2200 (2252), so there’s plenty of grunt in the water. This is advanced territory, so if you’re not confident, give it a miss.

There’s another interesting window late in the run, around Monday the 15th and Tuesday the 16th. The swell drops a bit but then kicks back up with a very long period of 21 seconds on the 16th morning. That’s a proper groundswell and with 8ft on the cards, it’s going to be big and powerful, so experts only. The catch is the wind is cross-onshore, which might chop it up a bit. It’s a promising but less certain call that far out.

Overall, the best bet for clean, powerful waves is that window around the 10th and 11th. The rest of the time you’re fighting the wind or dealing with marginal conditions. Crowds are only a possibility here, but on a clean day it’ll be worth the paddle.

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.
