Lances Left - surf spot statistics

Lances Left in Indonesia offers consistent surf conditions year-round, with ground swells dominating the mix at a near-constant rate of 87% or higher across all months. The swell size averages between 1.0m and 1.3m, peaking from May to September, making this the prime window for surfers seeking slightly larger and more powerful waves. During these months, the mean swell size reaches 1.2m–1.3m, with almost no wind swell interference, ensuring clean, well-formed waves. However, the wind conditions vary significantly—June provides the most favorable winds, with 53% good days, while August and September see a drop in offshore wind likelihood (36-38%), which can lead to choppier conditions. April and May also offer decent wind setups with 48-50% good days, though the swell is marginally smaller. The most challenging months in terms of wind are January, February, and December, where bad wind conditions occur around 60% of the time, potentially affecting wave quality. Overall, the best balance of swell consistency, size, and favorable winds occurs from April to July, with June standing out as the optimal month due to the highest chance of clean conditions. Late-season months like August and September still deliver solid swell but with a higher risk of onshore winds. For surfers prioritizing reliability, Lances Left rarely disappoints, though mid-year provides the most ideal combination of size and wind alignment.
