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.

In April, Inside Lefts offers generally favorable conditions for surfers, though wind variability can impact session quality. The average swell height is 1.4m with a solid 14.2s period, providing consistent, well-formed waves. Most swells come from the SSW (41.33% in the 1-1.5m range) and SW (16.26%), ensuring ideal angles for the break. Larger swells (1.5-2.5m) are present 22-25% of the time, mainly from the SSW direction, offering punchy, high-performance sections. Winds are the primary limiting factor, with only 35% of days delivering clean conditions. Offshore winds (light ENE to ESE) occur around 6-10% of the time, while problematic SE-SSW winds (15-30kph) dominate 15-20% of days, creating chop. Early mornings often see lighter winds, with glassy conditions most reliable when swell and wind align. Advanced surfers will find the most opportunity mid-month as SSW swells peak and wind interference lessens slightly. Overall, expect fun, head-high waves with occasional overhead sets, but scout for wind-protected sessions or dawn patrols to maximize quality.
