The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for the Sanur area over the next couple of weeks.
To be honest, it's a pretty frustrating outlook for Sanur Reef. Almost the entire 16-day window is ruled out by persistent cross-onshore winds that mess up what would otherwise be fun swell. The water temperature is sitting at 81°, which is pretty standard for this time of year, so no surprises there.
The first spot of interest doesn't pop up until Wednesday the 9th of September. Sunday the 30th of August through to Tuesday the 8th is a long, blank stretch of poor conditions, so you're looking at over a week of waiting. Even then, the only real standout is a single session on Wednesday morning.
Wednesday the 9th of September is your best bet by far. Early in the day, you'll see a clean 8 ft SSW groundswell with a period of 16 seconds. That's a proper swell with serious energy—the combined energy hits 2719, which is strong stuff. The wind swings offshore from the SW, which is rare here, and it's only a gentle breeze (9 mph), so the conditions will be clean and lined-up. The only catch is that this reef break is sheltered and it's an advanced wave; it can also be inconsistent. With the swell over 8 ft actually off the charts here at 8 ft, this is serious power, but it's not too big for a confident surfer on a good day. For the absolute best of the window, that Wednesday morning is the one.
The rest of the period is a struggle. That afternoon and the following days are all cross-onshore again, with the swell flickering between 5 ft and 8 ft. It’s all from the SSW, which is the optimum direction for this reef, but the wind just kills it. The energy levels are often strong—like 2573 on Sunday the 6th or 3956 on Friday the 11th—but it stays choppy and poor. For the second week, from the 8th onwards, you'll see more size and power rolling through, especially around Saturday the 12th and Sunday the 13th, but it’s still that frustrating cross-onshore wind. Nothing compares to that clean Wednesday morning burst.
If you're itching for a paddle, hold out for the 9th of September morning. Otherwise, kite surfers might find this whole period more interesting, given the consistent trades and solid groundswell.

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.
