The Lowdown
Alright crew, Rusty here. Gotta be honest, the outlook for Keramas is a tough one over these next couple of weeks. That cross-onshore wind from the SE just won't quit, keeping the surface bumpy and messy. Water temp is a touch warmer than normal at 82°F, so you’ll be fine in shorts.
We kick off Sunday the 19th with rain showers and that choppy wind. Swell is around 4ft from the SSW with a 13-second period, but it’s poor quality. This stays the same through the week. The wave energy is moderate (724), but blown out.
Monday the 20th and Tuesday the 21st don’t offer any relief. The swell builds to about 6ft on Monday from the SSW with a very long 17-second period, and energy jumps into strong territory (2236), but that cross-onshore wind just chops it all up. It’s only ever marginal.
The one real chance for a decent paddle is right at the end. Look to Friday the 31st of July and Saturday the 1st of August. The wind finally eases right off. Friday morning the 31st shows a near-glass 5 mph onshore breeze, with a clean 4ft SSW swell at a very long 18 seconds. Energy is strong at 1392. Friday afternoon the wind actually goes cross-shore from the ENE, also light. That’s your window. Saturday morning the 1st of August holds a similar story: light cross-onshore, 5ft SSW swell at 17 seconds, energy at 1405. That's the session to target. Because the period is so long, the reef will focus the energy nicely, but expect longer waits between sets.
Way out on Monday the 3rd of August, a big 10ft SSW swell arrives with massive energy (5946), but a moderate breeze will make it a choppy, expert-only zone. For everyone else, that setup looks better for a kite than a surfboard.
A rough forecast, overall. That persistent wind is the killer. The only light at the end of the tunnel is that last weekend of July and first of August.
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.
