The Lowdown
Alright, this is Rusty checkin' in from the Bali grid. We've got a solid look at our main man, Keramas, over the next couple of weeks. The water is sittin' at a warm 82°, which is about a degree and a half warmer than usual for this time of year, so a little extra tropical juice in the water.
So, the story for the next few days is a bit of a slow burn. The first real surfable action kicks off on Wednesday the 29th, but don't get your hopes up just yet. The wind is a cross-off SE breeze, but it's blowing across the swell, making for some choppy, poor conditions. The swell is a little 4ft to 4ft from the SSW, with a period around 14 seconds. The combined energy is moderate (809 to 763), but the quality just isn't there. It's a bit of a write-off.
Thursday the 30th and Friday the 31st see a slight improvement. The swell holds steady around 4ft to 5ft, but the wind switches to a light onshore breeze. The period stretches out to 15-17 seconds, which is a better, longer groundswell. The energy picks up into the moderate-to-strong range (1149 to 1308). The forecasts are still callin' it marginal, but the potential is there for some clean, lined-up waves if the tide plays nice. It's a pick-and-choose situation.
The first real standout of the period is shaping up for Saturday the 1st and Sunday the 2nd of August. We're seeing a jump in size to 5ft on Saturday, then 6ft on Sunday. The period is still solid at 16-18 seconds, and the combined energy is cranking, hitting 1628 on Saturday afternoon and a massive 1976 on Sunday morning. That's some serious push. The wind is light and variable, with a few periods of light offshore winds. This is the window where Keramas could really turn it on. It's still a little on the bigger side, but for the confident intermediate, this is the call.
The second week starts to build even more. From the 6th of August, we're looking at consistent 7ft to 7ft SSW swell. The energy is consistently strong (2415 to 2592). The wind stays a light to moderate cross-onshore, which will keep it a bit bumpy, but the raw power is there.
Then, hold onto your board. The real beast is building for the second week. Look at the 11th and 12th of August. On Tuesday afternoon the 11th, we've got a 10ft swell from the SSW with a 20-second period. The combined energy is a staggering 7982. That's a legit, solid groundswell. Then Wednesday the 12th, it's a 13ft monster from the S with a 19-second period, and an energy reading of 9723. This is very, very strong. This is expert-only territory. The wind is forecast to be a light offshore or cross-onshore, which is the best we can hope for with a swell this size. It's a long-range call, so don't book the plane ticket yet, but it has the potential to be the session of the trip. Just be aware that with a period this long (19-20 seconds), the sets will be very separated, and the wave will be fast and powerful, so it's a reef break that will reward the experienced.
So, to wrap it up: the first few days are a slow start with poor conditions. The weekend of the 1st and 2nd of August is your best bet for clean, fun waves in the 5-7ft range. The real heavy-hitter looks like it's arriving around the 11th and 12th of August, but that's a big, powerful, expert-only swell.

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.
