The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Keramas.

The next week and a half is a bit of a slow burn, to be honest. We’ve got a solid, long-period SSW groundswell filling in, but for the first few days, the wind is a bit of a party pooper. It’s not a total washout, but you’ll have to be patient.

Starting Tuesday the 28th and Wednesday, we’ve got waist to chest-high swell at 3ft to 4ft, but it’s coming with a moderate cross-onshore breeze. The water temp is sitting at 81°F, which is pretty average for this time of year. The energy is moderate (701 to 813) but the conditions are choppy and poor. Honestly, not much to write home about. Thursday the 30th sees the swell bump up to 5ft, and the energy is starting to build (1177 to 1327), but it’s still a bit cross-on and the surf is described as marginal. Friday the 31st the swell drops back to 4ft, but the wind lightens up, becoming lighter and even turning onshore. The period stretches to 17 seconds, which is a beautiful long groundswell, but the energy is still solid (1292). The surf is still just marginal.

The real shift happens as we move into the first week of August. Saturday the 1st through Tuesday the 5th, the swell holds steady between 5ft and 6ft, with periods of 14 to 18 seconds. The wind is generally light, sometimes cross-on or onshore, but the energy is climbing steadily, going from 1201 up to 1980 by Sunday afternoon. The conditions are still just “marginal” according to the forecast, but it’s getting cleaner with the lighter winds. The wave energy is moderate to strong.

Now, here’s where it gets interesting. The standout window looks like Thursday the 6th of August through Sunday the 9th. The swell is going to push up to 7ft to 8ft, with a very long period of 16 to 18 seconds. This is serious groundswell energy, with the combined energy values hitting 2845 and climbing to 4098. That’s strong to very strong energy. The wind is forecast to be light, often directly onshore, which is actually the offshore direction here, so it’ll be clean. This is a big, powerful, and very long-period swell. Because of the period, the waves will be best at this reef break, as it focuses that energy perfectly. However, at 8ft, this is expert territory. The break is known for being very consistent and gets crowded sometimes, so expect a few others in the water.

The best of the best is the Sunday the 9th. You’ve got an 8ft SSW swell with an 18-second period, and the energy is pumping at 4098. The wind is light and onshore, meaning it’ll be glassy. This is the one to circle on the calendar. It’s a bit of a wait, but it’s going to be worth it.

The following week, from the 10th to the 12th, the swell starts to ease back a little, staying in the 6ft to 8ft range with long periods, and the wind remains light. It’s still good, but the peak of the swell is definitely that Sunday.

So, overall, the first few days are a write-off for quality surfing. The real action kicks off around the 6th, with the standout being Sunday the 9th. Get ready for some serious, long-period groundswell at Keramas.

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.
