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 July, Sanur offers consistent surf with an average swell height of 2.0m and a strong 14.8s period, indicating powerful, well-spaced waves. The swell predominantly comes from the SSW (33.7% of waves in the 2-2.5m range) and SW (32.9% in the same range), delivering solid, surfable energy. Smaller contributions from SE and SSE directions add variety, though waves over 2.5m are rare (just 1.3% combined). Wind conditions are less ideal, with ESE and SE winds dominating at 30.5% and 21.4% in the 20-30kph range, respectively, creating cross-onshore chop; only 2% of winds are favorable for surfing. Expect rideable waves daily, but wind quality is inconsistent—early mornings may provide cleaner sessions before the breeze picks up. Advanced surfers will appreciate the punchy, longer-period waves, though wind management is key.
