The Lowdown
Right, Rusty here, with a look at what’s on the cards for Sanur Reef.
Right, let’s be straight with you. For the next week and a half, Sanur Reef is not going to be offering much for a surfer. The wind is stuck in a cross-on pattern from the east and southeast, keeping the surface choppy and messy. The swell coming in from the SSW has some decent period and energy – up to 16 seconds and a combined wave energy that hits four figures, topping out at over 1700 (moderate energy) – but the wind just won’t give us a break. The reef is a sheltered spot, so it doesn’t get the full brunt of it, but it’s still enough to ruin the clean lines you’d want from a wave. The water temp is a moderate 80°, right on the norm for this time of year.
Monday the 14th through to Saturday the 21st is basically a write-off. Everything is rated poor or marginal, with scores barely registering a tickle. We’re looking at clean-looking onshore breezes of 15 to 25 km/h, which is just going to keep things textured and ugly.
There is, however, a light at the end of this tunnel. As we look out into the long-range, things get a whole lot more interesting. The standout period, if it holds, is around the 27th of September. This is a real promise, but it's a long way off so don't count your chickens.
The morning of Sunday the 27th of September, we’ve got a serious pulse of energy arriving. Swell from the SSW bumps up to 8 ft with a very long period of 20 seconds. The combined wave energy shoots up to 6648 (strong wave energy), which is a serious amount of water moving. This is groundswell, no question. This kind of long-period, strong swell is classic for this reef, but with that size – over 8 ft – this is for experts only. The kicker is the wind is still a light 15 km/h from the SE, but it’s cross-on, so the quality is still in question. Afternoon sees it pumping at 10 ft with a 19-second period and 6595 (strong) energy. Same wind issue.
Monday the 28th of September is still very solid by local standards – 8 ft SSW swell dropping slightly to a 17-second period, with energy at 3997 (strong wave energy). The wind remains that light cross-on. It’s still only rated as marginal, but by the end of the run it’s the only real, powerful surf on offer.
Look, if the wind were glassy or offshore, that long-period, heavy SSW groundswell on the 27th and 28th would be an all-time day on Sanur Reef. It’s a quiet, advanced spot, so crowds are only a possibility. As it stands, it’s a big, powerful, and punchy wave that's going to be fighting that cross-on wind. Keep an eye on the forecast in the lead-up, because if that wind backs off, this is the one to call in sick for.
Until then, it’s a frustrating stretch. The breaks are inconsistent in this setup anyway, but a blank run like this isn't unusual for a sheltered, direction-specific break like this. You’d be better off with the kite for the next week, honestly.
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.
