Ombak Tujuh - surf spot statistics

Ombak Tujuh in Indonesia is a consistent year-round surf spot with predominantly ground swells, making it highly reliable for surfers. The best months for optimal surfing conditions are typically from April to June and November. During these months, the swell is almost entirely ground-generated (99% in April-May, 93-97% in November), ensuring clean, well-organized waves. The mean swell size increases from 1.6m in April to 2.0m in June, offering powerful but manageable waves for experienced riders. April and November stand out with the most favorable wind conditions—April has 55% good winds, and November has 49%, reducing onshore disruptions. May and June also provide solid waves (1.8m-2.0m) but see slightly less favorable winds (49-38% good wind days). The summer months (July-September) bring the largest swells (2.0m-2.1m) but suffer from strong onshore winds, with bad wind conditions peaking at 77-87%, making sessions challenging. December-March offers smaller waves (1.5m) and higher ground swell consistency, but wind conditions remain poor (60-69% bad winds). For the best balance of swell power, consistency, and manageable winds, April to early June and November are the prime windows to score Ombak Tujuh at its best.
