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.

February at Inside Lefts offers consistent surf with an average swell height of 1.4m and a solid 12.8s period, suggesting well-spaced, clean waves. Most swells come from the SSW (32% of waves in the 1-1.5m range) and SW (17% in the same range), generating quality left-handers. Larger waves (1.5-2.5m) are frequent enough (13-15% combined) for advanced surfers, while smaller days remain surfable. The main issue is wind—only 26% of the time are conditions ideal, with offshore/light winds. W to NW winds dominate (often 10-30kph), creating choppy or cross-shore conditions. If you score a day with lighter SSW or SW winds, expect peak performance waves, but prepare for variability. Prioritize early sessions when winds tend to be lighter. A solid month for committed surfers, though patience with wind is key.
