Balangan - surf spot statistics

Balangan, Indonesia, is a consistent surf spot with year-round swell, dominated almost entirely by ground swells (92–100% occurrence), making it highly reliable for quality waves. The swell size averages 1.5–2.2m, peaking from June to September with the largest waves (2.0–2.2m), ideal for experienced surfers. Wind conditions play a crucial role—the best months are April, October, and November, where good wind rates reach 60%, 72%, and 70% respectively, offering clean, offshore winds. March and September also provide decent wind conditions (41–51%). The worst winds occur from January to February and June to August, with bad wind rates exceeding 68%, often resulting in onshore chop. For optimal surfing, target the transition months (April, October, November) when solid swell meets favorable winds, or September if bigger waves are preferred. Avoid peak southwest monsoon months (June–August) unless willing to tolerate stronger onshore winds. Overall, Balangan delivers surfable waves year-round, but the best balance of size and clean conditions falls in April and late dry season (September–November).

October at Balangan offers excellent surfing conditions, with a consistent swell averaging 1.8m and a solid period of 14.2s, ensuring powerful, well-formed waves. The swell direction is predominantly from the SSW and SW, with the majority of waves falling in the 1.5-2.5m range, providing ideal size for intermediate to advanced surfers. Winds are favorable 72% of the time, mostly light to moderate (10-20kph) and coming from the SE to SSE, which helps keep the surface clean and groomed. Stronger winds (20-30kph) occasionally occur but are less frequent. The combination of a consistent, mid-sized swell and predominantly offshore or light cross-shore winds makes October a prime month for surfing at Balangan, with reliable, high-quality waves for those comfortable in overhead conditions. The long swell periods contribute to well-organized, powerful waves, though tidal variations should be monitored for optimal sessions.
