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.

October at Inside Lefts delivers consistent, mid-sized swells with an average height of 1.7m and a solid 14s period, ensuring well-shaped waves. The dominant swell direction comes from the SSW and SW, with the majority of waves falling in the 1.5-2m range (30.73% SSW, 14.73% SW) and a strong presence of 1-1.5m waves (14.66% SSW, 7.89% SW). Larger sets in the 2-2.5m range are less frequent but still occur (11.2% SSW, 3.61% SW). Wind conditions are the main challenge—only 13% of the time is ideal, as SE to SSE winds dominate, often blowing at 20-30kph (24.42% SE, 8.44% SSE), which can create onshore chop. However, lighter winds (10-20kph) from the SE to SSE offer cleaner conditions occasionally (6.58% SE, 3.27% SSE). Expect powerful, fast walls when the swell and wind align, but be prepared for variable wind quality.
