The Lowdown
Howdy, Rusty here. Let’s talk surf.
Right, we’ve only got one break in the frame—Keramas. The swell direction is SSW right through, which is the magic angle for this reef, but the wind is mostly out of the southeast, giving us cross-onshore breeze day after day. The water temp is 81°, right where you’d expect, no surprises there. But the lack of clean, glassy conditions means it’s never really firing. Still, there are a couple of sessions worth wetting a wetsuit-less leg for.
Sunday the 2nd: you’ve got about 6ft of SSW groundswell, period around 16 to 17 seconds, so plenty of grunt (combined energy of 1983 to 1943). Wind is light at 6 mph from the southeast, but it’s still cross-onshore. Surfable, a bit bumpy, but the reef will be working. Not a classic, but okay.
Monday the 3rd drops to about 6ft, period still 15 seconds, wind picks up to 9 mph in the arvo—gets choppy. Not ideal.
Now, the real highlight: Tuesday the 10th, afternoon session. Swell cranks to 8ft from the SSW with a 17-second period—that’s serious groundswell energy (combined energy of 3274). Wind is light from the SSE at 6 mph and straight onshore. That means a clean face but a bit of bump on the takeoff. For the pro crew, this is the window. The size puts it firmly in expert territory, so if you’re not solid, think twice. For those who are, the long-period SSW will draw beautiful, fast lines down the reef.
The rest of the run stays in the 5ft to 7ft range, but that wind never properly swings offshore. Saturday the 15th morning hits 8ft with a 16-second period—big, heavy, but still cross-onshore. Only for the brave and the strong.
In the second week, the pattern is the same: decent SSW swell, but the trade wind hangs on. The best you’ll get is a light breeze, but never glass. Crowds can be a thing at Keramas, so expect some company.
Honestly, this isn’t a classic forecast—more of a “if you’re keen and can handle some chop” outlook. But if you pick your moment, Tuesday the 10th arvo is the one to chase.
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.
