The best time to visit Indonesia is during its dry season from mid-April to September. The weather in this tropical country can be split into two seasons - dry and wet. Indonesia experiences its wet season in the remaining months from October to mid-April. The dry season has warm, sunny and dry days that offer the perfect conditions for trekking, sightseeing or other water-related activities. May, June and September are the ideal months to visit Indonesia if you wish to combine the excellent weather of the dry season with the lack of tourist crowds.
In regions like Kalimantan and Bali, the difference between the dry and wet season is not as extreme. The central Molucca islands experience contrastingly different weather conditions and make for a suitable destination if planning a trip in January. Temperatures throughout Indonesia are relatively consistent and hover around 28 degrees Celsius, irrespective of the time of the year. A surge in tourists is witnessed from mid-June to mid-September, whereas the wet season sees a drastic drop in tourist activity.
