Lombok-Komodo Sailing Season — Wind, Weather & Best Time 2026
The Lombok-Komodo sailing season runs April through October — Indonesia’s dry season delivering flat seas, optimal visibility and stable weather for yacht charter and liveaboard expeditions. This guide covers the meteorological details: monsoon patterns, sea state by month, swell heights, visibility predictions and how to plan around weather windows.
Indonesia’s Monsoon Cycle
Indonesia experiences two monsoons annually: the southeast monsoon (April-October) bringing dry weather and the northwest monsoon (November-March) bringing rain. The Lombok-Komodo region is in transitional zone, meaning monsoon effects are moderated compared to Sumatra or Java.
