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 May, Sanur offers surfers consistent but relatively small to medium-sized waves with an average swell height of 1.7m and a long, powerful period of 14.5s, indicating well-formed and clean waves when conditions align. The swell predominantly comes from the SSW and SW directions, with the largest share of waves (25.02%) in the 1.5-2m range from SSW, occasionally pushing into the 2-2.5m range (16.72%). Smaller contributions from SE and SSE suggest occasional variation. Wind conditions are less favorable, with only 3% of the time being ideal for surfing. The dominant winds are ESE (53.35% between 10-30kph), often creating onshore or cross-onshore chop, which can disrupt wave quality. SE winds (25.74%) also contribute to mixed conditions, while lighter winds from other directions are rare. Surfers can expect mostly rideable waves, but wind interference is frequent, requiring patience for clean sessions—early mornings or sheltered spots may offer better windows. Overall, May is decent for intermediate surfers but inconsistent for high-performance surfing due to wind.
