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 March, Sanur offers surfers consistent but relatively small conditions with an average swell height of 1.4m and a solid period of 13.6s, indicating clean, well-spaced waves. The dominant swell directions are SSW and SW, with the highest frequency of waves in the 1-2m range (SSW at 26-29% for 1-1.5m and 1.5-2m respectively). Larger swells over 2m are rare but possible, mostly from the SW. Wind conditions are favourable 44% of the time, with the majority of winds coming from the ESE to SE at 10-20kph, providing light to moderate offshore or cross-shore flow. Stronger winds (20-30kph+) are more likely from the WSW and W, but these are less frequent. Overall, March delivers manageable waves for intermediate surfers, with occasional punchier days when the SSW/SW swell combines with lighter winds. Expect mostly waist-to-head-high surf with good shape, though wind shifts can occasionally disrupt conditions.
