The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next 16 days for Ketewel look like a tough stretch. The cross-onshore wind is a persistent bastard, and even when there's swell, it's sloppy.
Let's start with the big picture. We're looking at a solid period of onshore winds from the SE and ESE, just hammering the place. The water temp is sitting at 81°F which is about normal for this time of year, nothing unusual there. The first proper surf window we can talk about is Wednesday, July 22nd, but it's a write-off.
From Wednesday morning (July 22) right through to the end of the month, it's a bad run. The swell is a mix of SSW groundswell, with periods around 13 to 17 seconds, and later some shorter-period SE windswell. The combined energy is moderate, but the wind is just ruining it. Every single session is marked by "poor surf conditions" – choppy, bumpy, cross-onshore trash. Not a single standout in that whole stretch.
We then get a bit of a gap. The first few days of August are still poor. Saturday the 1st is a no-go, and Sunday the 2nd sees a bump in swell to 6 ft from the SSW, with a 15-16 second period, but the wind is still a problem. Monday the 3rd is the same story.
Now, here's where it gets a little interesting, but only for the experienced crew. On Tuesday, August 4th, the swell kicks up. You're looking at 8 ft from the SSW with a long 18-second period. The energy is strong. That's a lot of water moving. For a reef break like Ketewel, that long period groundswell is going to produce some serious, powerful lines. But the wind is still cross-onshore, making it tricky. This is not for beginners – 8 ft with that power is expert-only territory, and the wind will make it ugly. The guidance says it's a "marginal" call, so it's a gamble.
Wednesday, August 5th, the swell drops to 7 ft but still with a solid 16-second period, and the wind eases slightly. The conditions are still "fairly choppy" but it's the best of a bad bunch. Still, only for the experts.
The real standout, if you can call it that, might be Thursday, August 6th. The wind drops to a light breeze from the SE at 6 mph. The swell is 6 ft from the SSW with a very long 19-second period. With the wind being light cross-onshore in the morning, it might clean up enough to offer a few good waves. That 19-second period is a proper groundswell, and it will focus on the reef. This is the only day in the whole 16-day window that has a hint of quality. Keep in mind, Ketewel is inconsistent and crowded sometimes, so you'll be sharing whatever good ones come through.
So, to sum it up: the first two weeks are a write-off. The only glimmer of hope is around the 6th of August, but it's a long way out and the forecast could change. For now, it's a waiting game.
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.
