The Lowdown
Alright, team, Rusty here, and I'm lookin' at the next couple of weeks for Keramas. Now, this is a tricky one. The swell is there, and it's coming from the right direction (SSW), but the wind is gonna be a constant pain in the arse. It's not a total washout, but you're gonna have to be patient and pick your sessions carefully.
The water is sittin' at a balmy 81°, which is pretty much spot on for this time of year, so at least you won't be cold while you're getting frustrated.
Right now, we're in a bit of a lull to start. The first few days are a write-off, with the wind messing up the surface. We're looking at a bit of a gap until things start to get interesting, but it's not a long wait.
The standout moment, the one that gets my blood pumping, is on Monday the 10th of August. The afternoon session is where it's at. The swell is set to pump at a solid 10 ft from the SSW, and the period is a very long 19 seconds. That's proper groundswell energy. The combined energy is a massive 6168, telling you there's some serious power in the water. The wind is light and from the SSE, which is directly offshore for Keramas. That's a magic combination. It's going to be pushing a bit over the 8 ft mark, so this is for the experts only. The long period means it'll be a bit more lined up and have those nice long lulls between sets, making the paddle out a bit easier for the crew who can handle it. The crowds might be there, but on a day like that, it'll be worth it.
For the rest of the week, it's a consistent run of 7 ft to 8 ft SSW swell, but the wind is stuck in the cross-on or onshore zone. The energy readings are solid, ranging from 2000 to 3218, showing there's plenty of push, but the surface is gonna be a bit scratchy. It's surfable, but it's not the pristine glass you dream of.
The second week gets a bit more mixed. There's another bump around Thursday the 13th of August with a 8 ft SSW swell and a light cross-on breeze, which is a slight improvement. The real standout, however, remains that Monday the 10th. The energy is lower by the 16th, dropping to the 1200-2000 range, and the wind picks up to a moderate breeze, making things choppy. The forecast for the end of the window, around the 19th, shows a return to 8 ft swell, but the wind is still a factor.
So, if you're an experienced surfer, circle Monday the 10th in the afternoon. That's your window. For the rest of the time, it's a case of making the most of the swell and dealing with the wind. It's not terrible, but it's not the cleanest Keramas we've seen.

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.
