Sanur - surf spot statistics

Sanur, Indonesia, offers consistent surf conditions year-round, with ground swell dominating the wave energy almost entirely (90–99% of the time). The best months for surfers are from January to March and November to December, when both swell consistency and favorable wind conditions align well. During these months, the mean swell size ranges from 1.4 to 1.5 meters, paired with good wind conditions around 44–54% of the time, making them the most reliable for quality surf sessions. Wind conditions deteriorate sharply from April to October, with unfavorable onshore winds prevailing 82–100% of the time, though the swell size increases slightly (peaking at 2.0 meters in July and August). While the bigger swells during the mid-year months may appeal to experienced surfers, the persistent bad wind conditions make these periods less ideal compared to the early and late-year windows. For the best balance of manageable swell size and cleaner offshore winds, target January, February, and December—when the chances of good surfing conditions are highest.

In October, Sanur offers fairly consistent surf conditions with an average swell height of 1.7m and a solid period of 14.1s, indicating clean, well-spaced waves. The predominant swell direction is from the SSW and SW, with the majority of waves falling in the 1.5-2.5m range, providing good surfable conditions for intermediate to advanced riders. Wind conditions are less favorable, with only 15% of the time being ideal for surfing—mostly light offshore or sideshore winds from the southeast and east. However, SE and ESE winds dominate, often blowing at 10-30kph, which can create choppy conditions, especially in the afternoons. Despite this, early mornings may offer cleaner sessions when winds are lighter. Overall, October delivers decent waves but requires timing to avoid onshore winds.
