The Lowdown
Alright folks, Rusty here. Grab a coffee and settle in. We've got a solid run of swell coming our way, but it's going to take a bit of patience to get the good ones.
Over the next 16 days, the waves are going to be pumping, but the wind is the main story. It's a classic trade wind pattern, blowing from the SE for most of the period. This means most of the time, our featured spot, Ketewel (a reef setup), is going to be dealing with a cross-onshore or onshore breeze. That's a real shame, because the swell is there.
Starting off this Saturday, August 8th, we've got a solid 8ft SSW groundswell rolling in with a very long 16-second period. The combined energy is a massive 2750 (strong). But the wind is a 9 mph cross-onshore, leaving it choppy. It's a marginal surf forecast, and honestly, not the best way to start. Sunday the 9th looks similar, with 7ft SSW swell but the wind picks up to 12 mph, making it even choppier. The whole first week is like this: plenty of size—we're seeing 10ft SSW swells on Monday the 10th and Tuesday the 11th, with energy readings over 4000 (very strong)—but the wind is just not cooperating. These waves will be powerful but messy. The water temp is about average for this time of year.
Now, let's look for a real standout. The closest we get to a clean session is on Monday morning, August 10th. The wind is still a light 9 mph cross-onshore, but it's the lightest breeze we'll see for a while. The swell is 6ft from the SSW with a 19-second period (very long period groundswell), and the energy is 3384. It's still not perfect, but it's the most manageable of the early week. This spot is a reef, so that long period should wrap in nicely, but it's inconsistent and only for the advanced crew.
Taking a look further out, the second week is a lot of the same story. Size drops a bit, but the wind remains stubborn. The best chance for a proper session might be Tuesday morning, August 18th. It's a week and a half away, so keep that in mind. The swell is a smaller 4ft, but the period is a very long 20 seconds. The wind is a light onshore 9 mph, and the energy is 2030 (moderate). For a reef break, that long period could produce some beautiful, lined-up waves, even if they're smaller. It's a glimmer of hope.
Then, from Wednesday the 19th, the swell kicks back up to 8ft from the SSW and the energy climbs back into the 3000s (strong). But again, the wind is on it. The wind stays on it all the way through to the end of the forecast on August 23rd.
So, what's the bottom line? The surf is here, and it's consistent, but the wind is making it hard to get a clean wave. If you're an advanced surfer and don't mind a bit of chop, you'll find plenty of power. If you're looking for a glassy, perfect day, you'll be waiting. The best bets are that Monday morning, August 10th, for the best combination of size and lightest wind, and that Tuesday morning, August 18th, for the promise of long-period lines on a smaller day. This spot is a reef, so stay sharp on the low tide.
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.
