The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way for Ketewel.
Alright, so we're looking at a pretty challenging stretch ahead. The forecast is filled with onshore winds and a lot of "marginal" or "poor" conditions, so we're going to have to pick our moments carefully. The overall pattern is a persistent SSW swell, but it's the wind direction that's the real spoiler here. The water temp is about what you'd expect for this time of year, nothing unusual.
Looking at the immediate forecast, we've got some swell on offer, but the conditions aren't really coming together. Friday the 4th through Sunday the 6th is a write-off, with cross-onshore and onshore winds making a mess of things. The swell is there, but it's not worth your time.
The first real chance to get something decent might be around Tuesday the 8th. The morning shows a solid 7ft SSW groundswell (period 13 seconds) with a light onshore breeze. The combined energy is moderate (2412), but the onshore wind will still put a bit of a bump on it. It's a marginal call, but if you're keen, it's the best of a bad bunch early on.
Things stay pretty average through the middle of the week. Wednesday the 9th has a similar story: 8ft SSW swell (period 16 seconds) with light onshore winds. The wave energy is decent (2609), but the wind direction is still not ideal for a clean face. It's not a standout, it's just the best of what's there.
The real interesting window, and the one that could be a standout, is shaping up for Thursday the 17th and Friday the 18th. We're seeing a solid 7ft SSW swell (period 17 seconds) on the Thursday morning, with the wind turning fully onshore. The combined energy is strong (2409). Friday the 18th morning looks even better on paper: 6ft SSW swell (period 15 seconds) with light onshore winds and a very high combined energy reading of 2892. This is the strongest wave energy in the whole outlook. Keep in mind this is a long-period groundswell (15 seconds and over 15 seconds), which means it's going to be a bit more lined up and powerful, but at a reef break like Ketewel (Indonesia), that's a good thing. It'll hold up well. The winds are still onshore, but light, so it could be the pick of the period. This is a promising one for the advanced crew, but it's a long way out, so keep an eye on it.
To sum it up: the first week is mostly a write-off with persistent onshore winds. The second week shows more promise, and the mornings of Thursday the 17th and especially Friday the 18th look like the best shots for a decent session. No beginners out there during those bigger swells.

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.
