The Lowdown
Alright, Rusty here again. Let’s break it down in feet and degrees.
The start of the run is a bit of a struggle. There’s swell, but the wind is mostly cross-onshore, leaving the surface choppy and unsatisfying. Not the time to get your hopes up.
The real window to watch is the 10th and 11th of August. On Monday the 10th, the afternoon brings a solid 8ft south-southwest swell, with the wind going light. The wave energy is strong, reading 3915 (moderate to strong). That’s a proper, long-period groundswell at 18 seconds, which means power and shape, but with longer waits between sets. At a reef like Keramas, that’s a good thing.
Keramas is a consistent, intermediate-level reef. With the 10th’s swell at 8ft, it’s definitely for experts. The water temperature is 81°, which is about normal for the time of year.
The best session is the afternoon of the 10th of August. Light wind, big swell from the right direction, and high energy. Expect crowds, because it’s a famous spot, but the quality will be worth it.
The second week has some bigger stuff, like the 13th of August with a 10ft south swell and 18-second period, but the cross-onshore wind messes it up. That’s a huge, powerful wave for experts only.
From the 15th onward, the wind picks up to a moderate breeze and the conditions go poor. The 17th and 18th have some more swell, but it’s still not clean.
Stick to the 10th and 11th. Everything else is either blown out or too big and messy.
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.
