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.

February at Bombies delivers solid surf conditions with a mean swell height of 1.4m and a healthy average period of 12.8s, indicating powerful, well-spaced waves. The dominant swell direction is from the SSW (32.32% in the 1-1.5m range, 13.34% in the 1.5-2m range), followed by SW and S, ensuring consistent, quality waves. While the majority of swells are in the 1-2m range, there are occasional larger sets (2-2.5m and above) from WSW and W, adding variety for advanced surfers. Wind conditions are favorable 41% of the time, with lighter breezes from the E to SE being ideal. However, stronger winds from the W to NW can occasionally create choppier conditions, particularly at higher speeds (20-50kph). Overall, expect punchy, clean waves with good power, though wind interference may require timing sessions carefully. A reliable month for experienced surfers.
