The Lowdown
Alright folks, Rusty here. Let's take a good hard look at what's on the table for the next couple of weeks.
Right off the bat, we gotta be real with you. The next few days are a bit of a write-off. We've got solid, long-period SSW groundswell rolling in, but the wind is just not playing ball. It’s not until Friday the 28th of August that we even get a sniff of something surfable, and even then, it’s a marginal call. The wind is onshore from the SSE at 9 mph, making a mess of what would otherwise be a nice 7ft, 16-second SSW swell hitting the reef. The combined energy is powerful at 2504, which tells you there's plenty of water moving, but the onshore breeze is just gonna chop it up.
Saturday the 29th morning is a similar story – the swell eases a tick to 6ft from the SSW, but still with that annoying onshore wind. Things don't really improve until we hit a bit of a gap. From Sunday the 30th right through to the end of the first week of September, the onshore wind just doesn't let up. We're looking at cross-onshore winds, mostly 9-12 mph, making everything a choppy, bumpy mess. The swell sticks around but it’s just not worth paddling out for. We’re looking at a solid stretch of days where there's no real quality on offer.
Now, hang in there, because towards the end of the period it gets interesting. On Thursday the 10th of September, we start seeing a shift. The wind finally turns light and *on*, giving us clean conditions. The swell picks up again, with a 6ft, 16-second SSW groundswell on Thursday afternoon, and the energy is 1499. That's a good sign. But the real standout is shaping up for Friday the 11th and Saturday the 12th of September.
The best bet, and I mean the one to circle on your calendar, is Ketewel on Friday the 11th of September. The swell jumps to 7ft from the SSW with a period of 17 seconds - that's a proper, long-period groundswell. The combined energy is pumping at 2895, so we’re talking strong, powerful waves. The wind is still a gentle cross-onshore breeze from the SE at 9 mph, which will keep things from being perfect, but it won't wreck it. For a reef break like Ketewel that's sheltered from the south, a 7ft SSW swell with that period is going to produce some heavy, grinding lines. This is advanced territory for sure. There’s also a chance of crowds, as it can get busy, but with those conditions, it's a risk worth taking. It’s not quite the glassy perfection we dream of, but it's the best we've seen in this entire run.
So there you have it. A long, quiet spell, then a potential cracker of a day on Friday the 11th of September at Ketewel. Get your planning sorted for that one.
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.
