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 February, Sanur offers decent surf conditions with an average swell height of 1.5m and a solid 13.0s period, providing well-spaced and powerful waves. The swell is predominantly from the SSW and SW directions, with the majority of waves falling in the 1-2m range—ideal for intermediate to advanced surfers. Around 54% of the time, the wind is favorable for surfing, mainly light to moderate (below 20kph) from the W and WSW, though stronger gusts can occasionally occur. Expect clean(ish) conditions in the mornings before the sea breeze picks up. While not the biggest or most consistent spot, Sanur can be fun for surfers looking for manageable but punchy waves with good shape. Offshore winds are rare, but the wave quality remains solid when swell direction aligns properly.
