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.

June at Inside Lefts brings consistent surf with an average swell height of 1.8m and a strong 14.9s period, resulting in powerful, well-formed waves. The dominant swell directions are SSW (51.2% of waves in the 1-2.5m range) and SW (34.8% in the same range), which align well with the break for long, hollow rides. Wind conditions are variable, with only 31% of days offering ideal offshore winds—mostly light ENE to ESE breezes (0-20kph). However, SE and ESE winds (20-40kph) are frequent (36.7% combined), which can create choppy conditions. The biggest windows for clean surf occur when lighter ENE or E winds prevail (around 3-5% of the time). Expect chest-high to well overhead waves (1.5-2.5m) on 70% of days, making June a solid month for experienced surfers who can handle occasional wind texture and strong currents.
