Indonesia’s weather is of tropical climate and it is considered to only have two seasons which is the dry season or the wet season. Being a wide country it may vary in the different regions, like between weather in Jakarta in comparison to weather in Bali, but generally, most of the country’s dry season is from April to October and the wet season from November to March. For highland temperatures, it is naturally cooler, with some peaks in Papua covered with snow. It is also cool in the mountains in Sulawesi.
Best time to go Indonesia
would be the dry season which is generally April to October so that you can get the best out of your time without having rain dampening your activities. But it is still possible to travel in the rainy season. It may still rain during the dry season and not rain for a week in the wet season, and it usually comes down in short blasts in the evening or late afternoons. Therefore if you must, traveling in Indonesia during the wet seasons is still possible if you do most of your sightseeings in the morning and early afternoons and rest in the evenings.
Take note also of peak seasons, which are July and August during the summer vacations of the Europeans and mid-December to late January for the Australian school holidays. This is especially obvious in the famous touristy places like Bali, Lombok and Gili Islands.
As for events and festivals, you may want to look out for major celebrations like Ramadhan and Christmas which are celebrated nationwide, Wesak (Buddha’s birthday) with procession around Borobudur and Nyepi (Hindu New Year) with people flocking Bali. You may well choose to avoid these dates, check on lunar and yearly calendar to confirm the dates, if you want to avoid the crowds.
