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).

April at Balangan offers solid surfing conditions with a consistent, well-structured swell. The average swell height of 1.6m combined with a healthy 14.3s period ensures clean, powerful waves—ideal for intermediate to advanced surfers. Swells predominantly arrive from the SSW (70% of waves between 1-2.5m), delivering well-defined, peeling rights and lefts over the reef. Wind conditions are favorable 60% of the time, with light to moderate ESE-SE breezes (10-20kph) being the most common, keeping surfaces groomed. However, stronger E-ESE winds (20-30kph) can occasionally create chop. Expect the most rideable waves in the 1.5-2m range (35% frequency), offering hollow sections and longer rides. Smaller days (1-1.5m) still provide fun performance waves, while larger sets (2-2.5m) deliver more power but remain manageable. Overall, April balances consistency and quality, making it a reliable month for good sessions, especially in the mornings before winds pick up.
