The Lowdown
Alright, Rusty here, let’s talk about what’s brewing. Honestly, for the next couple of weeks, it’s a bit of a tough stretch. There’s almost always some swell running, but the wind is the real villain here, and that’s locking out the quality for the most part.
The first few days are a write-off for a good session. The wind is persistent out of the ESE and SE, blowing cross-onshore at 12 to 13 mph, making a mess of what would otherwise be some decent-sized, long-period groundswell. The water’s sitting at 80°, which is pretty average for this time of year.
The real issue is that sweet spot. The swell direction from the SSW is a perfect match for Sanur Reef’s optimum direction, but the wind just won’t cooperate. The combined swell energy is huge – we’re talking a reading of 3037 on Wednesday the 12th, which is strong energy – but with that wind, it’s just choppy and poor. This trend continues for a solid week. The swell stays up, mostly between 5 ft and 8 ft, with periods of 15 to 17 seconds, which is proper groundswell, but the scores are still poor or marginal due to the wind. There’s a brief flicker on Wednesday the 19th afternoon where the wind switches to pure offshore for a window, but even then, the score is still marginal, so not enough to get excited about.
There’s then a lull in quality around the 20th to the 24th where the swell drops off significantly, down to around 4 ft to 5 ft, and the wind stays onshore. That’s a stretch of several days with no real hope.
The Best on Offer
If you’re looking for the cleanest window in this whole 16-day outlook, you’re going to have to be patient. Saturday the 15th and Sunday the 16th are the closest we get to something decent. The morning sessions on those days show the swell holding at 7 ft to 7 ft from the SSW with a 17-second period, and the wind is only a gentle breeze. It’s still cross-onshore, so it’s still a bit bumpy, but the conditions are the most manageable of the whole run. Saturday the 15th morning has a slightly better score, making it the pick of a rough bunch. The energy is still strong (2458), so there’s push, but don’t expect perfection.
After that, Tuesday the 26th morning shows a light breeze from the SE at only 6 mph, which is as close to glassy as we’ll get. That 6 ft SSW swell with a 14-second period could offer the cleanest, albeit smaller, waves of the whole period. The combined energy is moderate at 2136. It’s a real maybe.
The rest of the outlook is a tale of poor conditions and onshore chop. The swell stays, but the quality doesn't. This stretch is a test of patience for anyone wanting a clean wave at Sanur Reef.
That’s the long and short of it.
Rusty.

Information about the Sanur Reef Surf forecast
The above surf forecast table for Sanur Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sanur Reef can be found by selecting the local surf guide option on the grey menu. Our Sanur Reef 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 (Sanur Reef) 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 Sanur Reef 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.
Sanur Reef is 6 km (4 miles) from Denpasar. If you plan a holiday in Sanur - Bali, look for hotels and other accommodation in Denpasar. Denpasar has rooms for a wide range of budgets as well as car hire and transport links.
