The Lowdown
Alright, let's talk waves. We got a bit of a mixed bag coming up over the next couple of weeks. Not all-time, but there are some windows if you're keen.
The water's sitting about 80°F, so it's normal for this time of year. No worries there.
Ketewel (Bali) is our only spot in play. It's a sheltered reef, and it's inconsistent, so you gotta pick your moments. It doesn't break all the time, so if it's on, it's a bonus.
We're starting Thursday the 13th with a 8ft south groundswell at a 17-second interval. That's a lot of juice, with strong energy (3463), but the wind is a light cross-onshore breeze, making it choppy and lumpy. The tide's iffy too, so it's a skunk. The afternoon doesn't get any better.
Friday the 14th, the swell drops a little to 7ft, but the wind is still not your friend. Saturday the 15th is similar, with more 7ft SSW groundswell, but still junky.
We see a lull on Sunday and Monday, with the swell dropping to around 5ft to 7ft and the energy fading. Monday arvo is officially flat and bad. Tuesday the 18th picks up a bit with a clean 6ft south-southwest swell and lighter winds, but it's just okay.
The first real standout is Wednesday the 19th. We've got a solid 7ft SSW groundswell with a massive 18-second period. That's a proper groundswell with a lot of power behind it (2980 energy). The wind is still cross-onshore, but it's light, so it might be a few clean waves in there. This is for the experienced crew though, as 7ft is getting serious.
Then we slide into another iffy patch. Thursday the 20th holds at 8ft, but the wind stays on it. Friday the 21st turns poor with fresh winds and chop. Saturday the 22nd has rain showers and a 7ft swell, but it's all over the place.
The next week starts off weak, with the 23rd and 24th looking poor to marginal. Tuesday the 25th has lighter winds and a 6ft swell, which might be cleaner but not as big.
Then, on Wednesday the 26th, we get another pulse. A strong 8ft SSW swell with a 17-second period shows up, and the energy is the highest of the whole run (4221). The winds are light and cross-onshore, so it could be a good cleanup day if you're in the right spot. After that, Thursday and Friday of that week are looking like a washout with stronger winds and poor conditions.
So, mark your calendar for the 19th and the 26th. Those are your best shots for a proper wave. Everything else is mostly a combination of too much wind, not enough swell, or just poor timing. The second week is more of a hope than a promise, especially the 26th, so keep that in mind.
Keep your head on a swivel.

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.
