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 November, Bombies offers consistent surf with an average swell height of 1.4m and a solid 13.4s period, indicating powerful, well-formed waves. The dominant swell directions are SSW (47.1% of swells between 1-2.5m) and SW (36.5% in the same range), providing clean, long-period groundswells that peel perfectly for experienced surfers. While the SE wind direction is most common (35.5% of the time), only 9% of wind conditions are ideal—typically light offshore SSW-WSW breezes. However, strong SE winds (20-40kph) occur 24% of the time, potentially creating choppy conditions. The best sessions happen when SSW swells (1.5-2.5m) coincide with light WSW winds, offering hollow, barreling waves for advanced riders. Early mornings often have cleaner conditions before the SE trade winds pick up. Expect larger days when SSW swells push into the 2-2.5m range (22% occurrence), delivering Bombies' signature heaving tubes.
