The Lowdown
Alright, grab your board – let’s talk about what’s going on at Keramas. This is a proper reef break, exposed to the swell, and it’s very consistent. It likes a solid SSW swell, and that’s exactly what we’ve got lined up. The water’s sitting at 81°, which is about average for this time of year, so nothing freaky there.
The first real movement kicks off Saturday the 8th. We’ve got a 7ft swell from the SSW, with a very long period of 16 seconds. That’s a groundswell, and with a reef like Keramas, that’s going to be a good thing. The wind is light from the SE at 6 mph, and it’s blowing offshore, which is a big plus. The sets are carrying a lot of energy (2521). It’s a solid start, but the report says it’s marginal, so you’ll want to be picky with the tide. This is a call for the experienced surfer – anything over 8ft is expert territory, and we’re just under that.
Sunday the 9th is a bit of a letdown. The swell is still there at 7ft, but the wind shifts to a cross-onshore at 9 mph, and it’s going to get a little choppy. Still a lot of energy (2029 and 1971), but the surface won’t be as clean.
Now, keep your eyes on Monday the 10th. The morning is a bit messy with cross-onshore wind, but the afternoon is where it gets interesting. The swell jumps to 10ft from the SSW with an 18-second period, and the wind goes offshore again. The energy is very strong (4753). That’s a big, powerful groundswell. This is the standout of the first week. It’s only for experts at that size, and with that long period, the reef is going to handle it much better than a beach break. You’ll have long waits between sets, but when they come, they’ll be worth it. Expect crowds possible here – it’s a popular spot.
Tuesday the 11th holds the same size (10ft) and similar energy (4501 and 5717), with light winds. Still a go for the experienced crew. The swell stays solid through the middle of the week, but the wind stays cross-onshore or light offshore, keeping it a little on the tricky side.
The second week starts to fade. Swell sizes drop to 5ft to 6ft from the 17th, and the energy drops way down (998, 804). The wind is still a problem, staying cross-onshore. It’s not looking great for a while.
Then, around Wednesday the 19th, we see a spike. The swell picks back up to 8ft to 8ft very late in the forecast, with high energy (3743, 3785). But the wind picks up too, to 12 mph from the ESE, coming cross-onshore and making it choppy. It’s a lot of energy, but the surface won’t be pretty.
Friday the 21st is the other potential standout. The swell hits 10ft again with a 17-second period, and the energy is massive (5108). The wind stays light, but it’s cross-onshore, so it’s not perfect. This one is a “promising but less certain” call for the experienced surfer, as it’s far out.
Overall, the first week has the best chances, with Monday the 10th being the real highlight. The second week is a bit of a gamble. If you’re not an expert, the 10ft days are too big, so stick to the 7ft to 7ft days with offshore wind.

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.
