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 June, Sanur offers moderate to good surf conditions with an average swell height of 1.9m and a solid period of 14.8s, indicating powerful, well-spaced waves. The swell predominantly arrives from the SSW and SW directions, with the most consistent waves in the 1.5-2.5m range (47.36% combined for SSW/SW), providing punchy, rideable surf. Smaller days (0.5-1.5m) are less frequent but still occur. Wind conditions are less favorable, with ESE trades dominating at 10-30kph (53.77%), creating cross-shore or slightly onshore chop. Only 2% of the time does the wind align ideally for clean surf. Expect a mix of fun, mid-sized waves with occasional texture from the wind, requiring patience for the best sessions. Advanced surfers will appreciate the energy, while intermediates may find smaller days more manageable.
