The Lowdown
Alright, Rusty here. Let's get into it.
The long-range outlook is trying to build something, but for the first few days, it's a struggle. The wind is a real pain, blowing cross-on from the south-east, and that's messing up what could be a nice run of swell. The water is sitting at 81°, which is pretty normal for this time of year.
We start at Keramas on Friday the 24th. The swell is small, around 3ft, coming from the SSW with a period of 13 seconds. That's a long period groundswell, meaning it has some punch, but it's too small and the cross-onshore wind is making it choppy. The wave energy is moderate (705). Not a day to get excited about.
Saturday the 25th is similar. The swell picks up a touch to 4ft, still from the SSW, but the wind is still cross-on and the conditions are choppy. The energy is moderate (1004). It's still a struggle.
Sunday the 26th sees a jump in size to 8ft, but the swell switches to the SE and the period drops to 9 seconds. That's a short-period, wind-affected swell, and with the wind still cross-on, it's going to be a messy, lumpy mess. The energy is strong (1118), but it's not the kind of energy you want for a clean ride. This is getting into the territory for experts only, but the quality is poor.
Monday the 27th and Tuesday the 28th are a write-off. The swell is all over the place, wind is still cross-on, and the scores are bottoming out. Expect a few days of nothing special.
Now, things start to look a bit more promising from late in the first week into the second. The swell becomes more consistent, with a stronger SSW groundswell arriving. The wind is still cross-on, but it's forecast to be lighter at times, with a few "on" and "light breeze" periods.
The standout window is looking like Saturday the 1st of August and Sunday the 2nd of August. The swell is a solid 5ft to 7ft from the SSW, with a very long period of 16 to 18 seconds. That's a proper groundswell. The wind is forecast to be light, with some periods of offshore and light cross-on. The energy is very strong (2665 and 2654). This is the best the forecast has to offer. The long period means the sets will be clean and powerful, but it might be a bit too straight for the beach break, so keep an eye on the tide. Crowds are sometimes an issue here, and with this quality, expect some company.
After that, the swell holds through the 5th of August, with 7ft SSW swell on the Wednesday morning and a light cross-on wind. The energy is very strong (2233). This is another solid day, but the wind might be a bit more of a factor.
The rest of the second week stays surfable, with moderate to strong energy and a consistent SSW swell, but the wind is always a bit of a gamble. It's worth keeping an eye on the 7th and 8th of August, where the swell is still 7ft and the winds are looking lighter again.
So, to sum it up: the first few days are a write-off. The best bet is on the weekend of the 1st and 2nd of August, with the chance of some clean, powerful SSW groundswell. The 5th of August is also a strong contender. It's not a classic, but there's some good surf to be had if you pick your window.
Rusty.

Information about the Keramas Surf forecast
The above surf forecast table for Keramas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Keramas can be found by selecting the local surf guide option on the grey menu. Our Keramas 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 (Keramas) 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 Keramas 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.
Keramas is 10 km (6 miles) from Klungkung. If you plan a holiday in Sanur - Bali, look for hotels and other accommodation in Klungkung. Klungkung has rooms for a wide range of budgets as well as car hire and transport links.
