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.

July at Bombies, Indonesia, delivers powerful and consistent surf, with an average swell height of 1.9m and a solid 14.9s period, indicating well-spaced, clean waves. The swell is predominantly from the SSW and SW directions, with the largest concentration of waves in the 1.5-2.5m range—SSW swells alone make up over 43% of waves in this size bracket, offering ideal conditions for advanced surfers. The wind is less favorable, as ESE to SSE winds dominate, often blowing at 20-40kph, which can create chop or cross-shore conditions. However, there’s still a 7% chance of clean, offshore winds, typically when winds swing from the N to ENE. For experienced surfers, July provides reliable, high-energy waves, though patience is needed for those rare pristine days with lighter winds. Expect powerful, barreling sections and some wind-affected sessions, but the swell consistency makes it a prime time to score quality waves.
