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 November, Sanur offers mostly manageable surf conditions with an average swell height of 1.5m and a solid period of 13.5s, indicating consistent, well-spaced waves. The swell is predominantly from the SSW and SW directions, with peak activity in the 1.5-2m range (23.24% from SSW and 16.23% from SW), providing clean, surfable waves. Smaller swells (1-1.5m) are frequent from the SW (21.87%), while larger swells (2-2.5m) appear occasionally, mostly from SSW (5.85%). Wind conditions are favorable for surfing 33% of the time, with the most common winds being light to moderate (10-20kph) from the SE, SSE, and ESE. However, stronger onshore winds from the SE/ESE can occasionally create choppy conditions. Overall, November is a decent month for intermediate surfers, with the best sessions occurring during lighter wind periods when the SSW/SW swells deliver well-shaped waves. Advanced surfers may find larger days less frequent but worth waiting for.
