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 January, Sanur offers decent surf conditions with an average swell height of 1.5m and a solid period of 12.9s, indicating well-formed, powerful waves. The swell predominantly arrives from SSW and SW directions, with the majority of waves ranging between 1-2.5m, providing consistent, rideable surf. Around 53% of the time, winds are favorable for surfing, mostly light (below 20kph) from WSW to W, though stronger onshore winds can occasionally disrupt conditions. The spot works best when winds stay offshore or light cross-shore, which is frequent enough for good sessions. Surfers can expect clean, mid-sized waves with occasional larger sets, making January a reliable month for intermediate to advanced riders. Keep an eye on wind forecasts, as westerlies can occasionally become too strong and chop up conditions.
