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 April, Sanur offers consistent surf conditions with an average swell height of 1.5m and an impressive period of 14.2s, indicating powerful, well-spaced waves. The swell predominantly comes from the SSW and SW directions, with SSW producing the highest percentage of rideable waves (30.93% in the 1.5-2m range), making it the primary swell direction for quality surf. However, the wind is often a limiting factor, with only 18% of conditions being ideal for surfing. The prevailing winds are from the ESE and E, often blowing in the 10-30kph range, which can create choppy or cross-shore conditions, especially during midday. The best sessions likely occur early mornings when winds are lighter. Intermediate to advanced surfers will find the most success, as the combination of moderate swell size and long period allows for steep, barreling waves when conditions align. Keep an eye on wind forecasts for those rare glassy days.
