The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the coming weeks.

We’re focusing on the east coast, and the pick of the bunch is the world-class reef at Keramas. This spot is very consistent, so it’s always in the conversation. The water here is sitting right around average for this time of year, so no surprises there.

The outlook kicks off on Monday, 24 August. We’ve got a solid 6ft swell pushing in from the SSW, with a very long period of 16 seconds. That’s proper groundswell energy. The combined energy is a strong 1660, which is a lot of water moving. However, the wind is a cross-onshore breeze at 9 mph, leaving it a bit lumpy and choppy. The tide conditions are also not playing ball, so Monday morning is a write-off for a clean session. The afternoon doesn’t look much better, with the same issues.

Tuesday, 25 August, sees the swell drop a touch to 5ft, still from the SSW with that lovely long 16-second period. The combined energy is still solid at 1190. But again, that persistent 9 mph cross-onshore breeze is keeping things messy. The tide is still a factor, so it’s a frustrating watch.

Wednesday, 26 August, is a real low point. The swell drops to 5ft with a period of 14 seconds, and the energy is down to 824. The wind is directly onshore, making for poor conditions. It’s a day to leave the boards in the car.

The end of the week is where things get interesting. Friday, 28 August, brings a proper pulse. The morning shows a solid 8ft SSW swell, still with a 16-second period. The combined energy rockets up to 3069 – that’s serious power. The wind is onshore, but it’s a light 6 mph in the afternoon. This is a big swell, over 8ft, so this is strictly for experts. The wind cleans up enough in the afternoon to make it tempting, but it will be a beast of a paddle.

The first week of September keeps the swell alive. Tuesday, 1 September, offers another 6ft SSW swell with a 17-second period in the afternoon, and the wind drops to a light 6 mph. The energy is a strong 1933. This is a standout moment – that long period and light offshore wind are a real treat for a reef like Keramas, giving it that classic, fast, hollow shape.

Into the second week, the swell hangs on. By Sunday, 6 September, we see another noteworthy pulse. The afternoon has a 6ft SSW swell, but the period stretches to a massive 18 seconds. The combined energy jumps to 2377, and the wind is a light 6 mph onshore. This is a promising long-range signal, but it’s a bit further out, so keep an eye on the forecasts.

Overall, the best window looks to be the afternoon of 1 September and the afternoon of 6 September. The 1st is the more reliable bet with that light wind and clean conditions. The 6th is a promising long-range gem. The rest of the period is a mix of consistent swell but frustrating onshore winds.

Rusty, signing off.

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.
