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.

March at Inside Lefts delivers consistent surf with a solid average swell height of 1.4m and a healthy 13.4s period, indicating well-formed, powerful waves. The dominant swell directions are from the SSW (63.1% of waves in the 0.5-2.5m range) and SW (24.1%), ensuring clean, rideable lines with good energy. While smaller days (0.5-1.5m) occur frequently, larger sets (1.5-2.5m) make up a notable 25% of conditions, offering punchy sections for advanced surfers. Wind is a mixed bag—only 28% of the time is it ideal (likely light offshore E/NE breezes), but problematic onshore W/WNW winds (30-40kph) do appear. Expect peaky, hollow waves when winds align, though mornings may provide cleaner windows before sea breezes kick in. A solid intermediate-to-advanced month with occasional overhead barrels, but patience may be needed for optimal conditions.
