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.

January at Bombies, Indonesia, offers consistent surf with an average swell height of 1.4m and a solid 12.6s period, ensuring well-formed, powerful waves. The swell predominantly comes from the SSW (29.09% between 1–1.5m) and SW (21.79%), with a decent contribution from the S (4.72%) and WSW (2.62%). Larger waves in the 1.5–2.5m+ range are frequent, particularly from the SSW (13.53% combined) and SW (5.64%), delivering punchy, hollow sections ideal for experienced surfers. However, wind conditions are hit-or-miss, with only 37% of days offering ideal offshore or light cross-shore winds. The dominant winds blow from the W and WNW, often at 10–30kph (6.36–8.05%), which can create choppy onshore conditions. When winds align from the SE-SSW (lighter 0–20kph ranges), cleaner surf prevails. Overall, January provides strong, high-energy waves, but patience is key for optimal wind setups—mornings may offer cleaner conditions before afternoon winds pick up. Suited for advanced surfers due to the power and occasional size.
