The Lowdown

Alright, listen up. Rusty here, giving you the straight story on the surf for the next couple of weeks. We've got a bunch of SSW groundswell in the water, but don't get too excited just yet – most of it's wrapped up in messy, marginal conditions.

First look at the water is early tomorrow morning, the 8th. There's about 5ft of SSW swell, with a solid 2582 combined energy. But it's just not happening. There's rain around, a light SSE breeze, and the waves are looking average. The water's a warm 81°, which is normal for this time of year.

It picks up a touch to 6ft on Tuesday afternoon, but the call is still marginal. The period is a long 18 seconds, so there's a lot of push, but the shape is off.

Wednesday the 9th is the biggest of this first batch, with 8ft in the morning and 8ft in the afternoon. That's getting serious – it's over 5ft, so it's not for beginners, and it's over 8ft, which means it's experts-only territory. The period is still 16 seconds, so it's powerful, but the wind is light from the SSE which is offshore and could make it good. But still, the forecast has it as marginal, so the tide's probably messing with it.

Then we get a long, dull patch. From Thursday the 10th through to the 14th, it’s just a run of average days. Wave heights float between 4ft and 7ft. The periods are 15-16 seconds, but the wind turns cross-on from the SE at about 9 mph. It's going to be choppy and not clean. It's a grind.

There's a brief uptick on Sunday the 13th with 7ft on the afternoon, but that cross-on wind is still there. It's not worth getting excited about.

From the 15th to the 19th, the swell backs right off. We're looking at 4ft to 6ft. The period drops to 13-15 seconds, and the energy weakens. There are a few windows with light winds, but the swell is too weak to do much with it.

The standout for the whole run is shaping up for Tuesday the 22nd. That's over a week away, so it's a long-range call, but the models are showing a proper pulse of SSW groundswell. We're talking 7ft in the morning, building to 7ft in the afternoon. The combined energy jumps way up over 3300, which is a strong signal. The period will be around 16-17 seconds, so it will have real power. And on the Tuesday afternoon, the wind is light from the SSE, which is offshore at Keramas. That's the recipe for a clean, glassy day. This is the one to circle on the calendar.

There's another solid pulse on the 23rd, with 7-7ft. It's still good, but the wind is a bit more on it. Still, a better option than most.

So, the long and short of it is: there's a long stretch of average-to-poor surf from the 10th to the 21st. If you want the best of it, save your energy for the 22nd and maybe the 23rd. That's where the real potential is. The early days have size, but they're a gamble.

Rusty out.

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.
