Inside Lefts - surf spot statistics

Inside Lefts in Indonesia offers consistent year-round ground swells, with minimal wind swell interference, making it a reliable surf destination. The best months are from **April to June**, when ground swell dominance is at its peak (98-99%), swell size increases (1.4m to 1.8m), and wind conditions are relatively favorable (35-38% good winds). April and May stand out as the prime months, combining solid swell consistency with the highest likelihood of offshore or light winds. June follows closely, though wind quality slightly declines. The swell grows larger from **May to August**, with July and August seeing bigger waves (1.9m-2.0m), but wind conditions deteriorate significantly (only 9-21% good winds), making these months better for advanced surfers willing to endure cross-shore or onshore winds. **September to March** remains surfable, but the increasing frequency of bad winds (72-93%) and smaller swell size (1.4m-1.7m) reduce consistency. December to March still provides decent ground swell (82-93%), though wind conditions are less reliable (only 19-28% good winds). Overall, **April to June** delivers the best balance of size, consistency, and favorable winds for most surfers.

May at Inside Lefts offers solid surf conditions with a dominant swell direction from the SSW and SW, producing consistent, well-formed waves. The average swell height is 1.6m with a strong period of 14.6s, ensuring powerful, clean waves that are ideal for experienced surfers. Most swells fall in the 1-2.5m range (70% of the time), providing a good mix of overhead and head-high waves. Winds are onshore from the SE to ESE 38% of the time, which keeps conditions clean, though stronger winds (20-40kph) can occasionally create chop, particularly in the afternoons. Early mornings often see lighter winds, making for optimal sessions. Overall, May delivers reliable, high-quality waves with favorable winds, though patience may be needed for the best windows.
