Bombies - surf spot statistics

Bombies in Indonesia is a world-class reef break known for its powerful, barreling waves, and the data shows consistent swell year-round. The best months for surfing here are from April to September, when ground swell dominates (93–99%), ensuring clean, organized waves with minimal wind swell interference. During this period, mean swell size increases from 1.4m in April to a peak of 2.0m in August, offering ideal conditions for advanced surfers seeking bigger, more powerful waves. However, wind conditions deteriorate significantly from May onward, with bad onshore winds prevailing 77–98% of the time, particularly worst in August and September (98%). Despite poor winds, the swell consistency and size make it the prime window for experienced surfers willing to tolerate gusty conditions. The shoulder months like March and October still provide strong ground swell (93–96%) but with slightly better wind percentages (32% and 4% good winds, respectively). November to February sees smaller swells (1.4m) and higher wind swell influence (up to 18%), but better wind conditions (21–41% good winds) make these months more suitable for those prioritizing cleaner faces over raw power. Overall, the core season (May–September) delivers the heaviest and most consistent waves, while the off-season trades size for cleaner but smaller conditions.

In August, Bombies offers consistent, powerful surf with an average swell height of 2.0m and a solid 14.8-second period, indicating well-organized, powerful waves. The dominant swell directions are from the SSW (46.7% of waves between 1.5-2.5m+) and SW (26.1% in the same range), delivering clean, long-period energy that aligns well with the break. Smaller contributions from S and SSE swells add variety. Wind conditions are less favorable, with only 2% ideal offshore winds; the majority are onshore from the ESE to SE (60.3% between 20-50kph), creating choppy or cross-shore conditions. However, the spot’s exposure to southern swells ensures rideable waves even with moderate wind, though the best sessions will be rare early mornings with lighter winds. Expect overhead to double-overhead waves, but patience is key for clean conditions.
